Grand Kankakee Marsh

The Grand Kankakee Marsh (or Great Kankakee Marsh or Kankakee Marsh) of northern Indiana and northern Illinois was one of the largest wetlands and freshwater marshes in the contiguous United States, and was frequently referred to as "The Everglades of the North". The marsh was formed by melting glaciers during the Late Pleistocene, approximately 13,000–16,000 Years Before Present (YBP). It was the home of Indigenous nations for thousands of years until the Indian Removal Act in the 19th century.

The marsh existed within the Kankakee River drainage basin's . Its estimated size ranged between to over across , and its main tributary, the Kankakee, was over long with over 2,000 meander bends. Its flat elevation of maintained the land wet most of the year.

The Kankakee Marsh was a mosaic of marsh, swamp, bog, fen, forest, prairie, wet meadow, oak savanna, and barren vegetation. Countless fish, reptiles, amphibians, insects, invertebrates, birds, and semi-aquatic mammals inhabited the marsh. Its habitats consisted of vast, open stretches of shallow water with island ridges, aquatic plants (e.g., cattails, wild rice), shrubs (e.g., willows, dogwoods), and trees (e.g., maples, oaks). Notable features included English Lake, formed by the confluence of the Kankakee and Yellow rivers, and Beaver Lake, the largest lake in Indiana until the 1880s. The marsh provided spawning grounds for fish from the Illinois River.

Settlers, syndicates, land speculators, and the Indiana General Assembly gradually destroyed the marsh between 1882 and 1917 by channelizing rivers and streams. The Kankakee River became one of the largest drainage ditches in the U.S. The Indiana side of the Kankakee River is called the Marble Power Ditch. The draining of the marsh turned it into a major agricultural region, enabling its nine counties to generate over $1.6 billion in 2022 from the monoculture of corn, soy, wheat, and other crops.

The channelization of the Kankakee River has caused serious environmental issues over the last century, including floods and erosion. Siltation, suspended solids, nutrient pollution from farm runoff, and other issues have degraded water quality, requiring state and community partnerships to invest millions of dollars in soil and water conservation and stabilization programs. Extreme fluctuations in high and low flow water levels have degraded the environment and reduced wildlife habitat, causing significant biodiversity loss.

The destruction of the Grand Kankakee Marsh contributed to Indiana's total wetland losses of 87%. Its history exemplifies how Indigenous peoples were forcibly removed and ecosystems destroyed for development. The marsh's history of destruction is similar to that of Tulare Lake in California, and the Great Black Swamp in Indiana, Ohio, and Michigan. In recent years, attention has grown to the history of destroyed environments and drained wetlands, like the Grand Kankakee Marsh. This attention has contributed to important policies on wetland conservation (both American and international), natural resource management, wildlife conservation, and global efforts to prevent forced Indigenous removal, pollution, resource depletion, environmental degradation, ecocide, ecosystem collapse, and extinction caused by humans.

Natural history of the marsh

Geology and hydrology

The Grand Kankakee Marsh developed on the till plains and moraines left by the retreating Laurentide ice sheet in northern Indiana and northern Illinois following the Last Glacial Maximum 24,000 Years Before Present (or YBP). During the Late Wisconsin Episode's Woodfordian Substage (20,000–14,000 YBP), deposits of diamicton, limestone, shale, and dolomite fragments across the Kankakee till plains resulted in silt clay-loam to clay soils. The Kankakee River Basin's bedrock is Cambrian, Ordovician, Silurian, Devonian, and Mississippian. Freshwater flows through dolomite and limestone Silurian-Devonian aquifers within the Kankakee Arch.

The Kankakee Torrent (19,000 YBP) occurred when the ice sheet discharged large volumes of meltwater. This mega-flood deeply eroded earlier valley deposits of clay, silt, gravel, and sand, depositing thick outwash later reworked by wind, along with sand from the Valparaiso Moraine, into aeolian dunes. The torrent also redirected the Illinois River and formed Lake Chicago (14,000–11,000 YBP), which developed between the ice and the Valparaiso Moraine as the Lake Michigan ice lobe retreated. Lake Chicago occurred in three stages: the Glenwood, 14,000–12,700 YBP, above Lake Michigan; Calumet, 12,700–11,000 YBP, above Lake Michigan); and Toleston, 5,000–4,000 YBP, above Lake Michigan. These glacial and flood features are visible in Lidar DEM and aerial imagery.

Isosatic rebound caused the Earth's crust to uplift, draining the Great Lakes until 3,000 YBP. As the Saginaw Glacier melted, meltwater flowed over the Mississinewa Moraine into the Kankakee and St. Joseph valleys, transporting vast quantities of sediment westward. Proglacial meltwater dynamics and variable-energy glacial floods deposited a thick sequence of sandy outwash, measuring , extending from the Valparaiso Moraine to the Kankakee River's headwaters in St. Joseph County. .

Lake Kankakee developed within the Kankakee valley 14,000 YBP, likely consisting of a shallow lake or a series of wetlands. The lake bottom contained decayed vegetation and sandy gravel loams. Its sand dune region covered , with water levels reaching 40 feet (12 m) above the present-day Kankakee River. Sand dunes were either dry and barren, or wet and vegetated.

The natural draining of Lake Kankakee exposed a nearly flat bedrock surface covered by thin Pleistocene drift, with outwash sand and gravel prevailing over lacustrine deposits. Peat formed in glacial lake basins, between sand dunes, and within ancient meander channels and kettles. Sand and gravel beds formed aquifers as modern soil developed 14,000–13,000 YBP.

The 8.2-kiloyear event, a rapid drop in global temperatures, induced two phases of wind-blown loess deposition across northern Indiana and northeast Ohio 8,950–8,005 YBP. Loess was rich with freshwater fossil shells. Marl deposits consisted of shells from Physa, Planorbis, Unio, and other mollusk species. Drift levels vary by county, reaching depths of up to . Blue glacial till existed below the sand.

The Kankakee Marsh's headwaters featured knob and kettle topography. Soil distribution followed terrain: Entisols formed along streambanks, Alfisols developed under forest vegetation on dry moraines and well-drained areas, Mollisols developed under prairie and marsh vegetation, and Histosols occupied wetlands. Higher elevations contained organic-rich lacustrine deposits of muck, gravel, marl, and peat, while lower elevations toward the Illinois border exhibited sand-gravel alluvium and glaciofluvial valley trains. These trains comprised stratified loamy to coarse sand and gravel, often surmounted by aeolian dunes of well-sorted fine sand. Yellow River's headwaters consisted of gravel; its confluence with the Kankakee, forming English Lake, contained fine, yellowish sand, in contrast to the gray, bluish till found in other Kankakee streams. The region between the Kankakee and Iroquois rivers featured low ridges of pure yellow or white sand interspersed with wetlands.

Sand ridges and hills formed irregular belts wide and high, creating islands across the undulating landscape. Certain areas contained coarse gravel and large boulders, including granite deposits in Jasper and Pulaski counties where limestone rose near the surface. At the Illinois border, limestone is often exposed above the river. The limestone thickens near Beaver Lake and creates a ledge in the Kankakee River at Momence. This ledge was considered to be a natural dam, backing up river waters and facilitating the development of marsh soil.

Marsh soils contained minerals and trace elements. Decomposing plants created bog iron in the marsh. Eleven distinct soil types developed near the Illinois border, consisting of loam, sand, peat, and clay. Peat could be deep in some places. Muck and peat areas were often underlain by marl, lime, sand, and clay, and had a high water-retention capacity.

The 1835 drought caused the marsh bottoms to dry and crack. Spring floods caused the marsh to expand 1–5 miles (1.6–8 km) from the Kankakee River for eight to nine months annually. Historical size estimates of the Kankakee Marsh range from to over . Its small islands were , its flat elevation was , and its floodplain was long and wide under of water. The marsh's size was increased by adjacent marshes along the Tippecanoe River. Seasonal floods converted the land between the Kankakee and Iroquois rivers into a massive wetland.

Historians noted how the river "writhed and twisted and turned back upon itself in a series of startling zigzag movements" across . Father Stephen Badin documented over 2,000 meander bends along the stretch from South Bend to Momence. A 1981 geological study confirmed the river's length was , with elevation dropping from over at the headwaters to at the Illinois border. The river's average speed was approximately , allowing terrace swamps to form. Deep gravel deposits in sand and till caused streams to flow sluggishly.

Sandy deposits dominated the marsh, with localized exposures of boulder clay and glacial till along the borders of Starke and Jasper counties. These clay deposits formed basins for small lakes, such as English Lake at the confluence of the Kankakee and Yellow Rivers. Groundwater supplied some of these lakes, while others were recharged by rainfall or small streams with outlets draining into the Kankakee River. Peat deposits with sandy subsoils ran parallel to the river.

Rivers support lakes and wetlands. The Kankakee riverbed consisted primarily of sand and gravel. The water was clear and pure. It contained iron and other minerals. Aquifers fed springs and flowing wells. Wetlands contained carbonic acid, producing calcareous and chalybeate springs, and forming calcareous tufa and bog iron. Water hardness in sand and gravel of Pleistocene age correlated to the Kankakee River's overflowed outline and its main wetland extents. Groundwater levels fluctuated due to precipitation recharge, evapotranspiration, and natural discharge to streams and springs.

Biodiversity

The Kankakee valley experienced arid conditions during the Bølling–Allerød Interstadial (14,690–12,890 YBP) and the Younger Dryas (12,900–11,700 YBP). Around 11,000 YBP, the climate transitioned from boreal to temperate. This shifted postglacial vegetation from open spruce forest-tundra to temperate deciduous forests, with deciduous trees supplanting conifers on the till plains by 9,800 YBP, followed by the development of open oak woodlands 8,000–4,000 YBP. Proglacial lakes also influenced climate patterns as winds interacted with changing lake surfaces 14,200–10,500 YBP. Flora migrated through land connections, waterways, wind dispersal, or avian vectors. By 6,000 YBP, precipitation and summer temperatures reached modern levels; by 3,000 YBP, northern hardwood forests, including oak-hickory, sugar maple, and beech were firmly established.

Early Holocene warming trends caused wildfires that triggered grassland expansion from central Illinois and Indiana toward Lake Michigan, though the Kankakee Marsh's wetlands served as a firebreak. Fires destroyed protective vegetation on sand dunes, leaving them vulnerable to wind erosion until vegetation regrowth stabilized shifting sand ridges. The first French explorers witnessed natural wildfires and fires set by Indigenous peoples for land modification in 1679.

The marsh persisted in a humid region east of the Mississippi, with its summer isothermal position placing it within the Dfa climate type of the Köppen system. The region has been described as a "Banana Belt", due to milder winters compared to surrounding areas. North of the Kankakee River featured high-moisture winds. In the 1830s, extreme winters and unseasonable colds killed wildlife and buried the region in deep snow, challenging early settlement.

The Kankakee River's meandering floodplain created biodiverse ecosystems, including oxbow lakes and freshwater marshes with aquatic plants. It contained forested swamps, shrub swamps, alkaline fens, sphagnum bogs, vernal pools, wet meadows, and sloughs. River banks were very low and consisted of sand dominated by trees and vegetation. Prairies, oak savannas and barren vegetation stood above the marsh with loam over clay soils, and stands of old-growth hickory, ferns, cherry, walnut, sphagnum, and other vegetation.

Minerotrophic marshes in lower elevations were influenced by white or bluish clay. Ombrotrophic peatlands, such as Lydick Bog in St. Joseph County, were more frequent at higher elevations. Surface and groundwater dynamics, often altered by beaver dams, shaped biogeochemical cycles and vegetational diversity. While saturation preserved peat, drier conditions promoted peat oxidation.

At the marsh's headwaters, species included Tamarack, roundleaf sundew, pink lady's slipper, and bog birch. Acidic peat soils fostered cranberry, Jack-in-the-pulpit, and yellow bartonia. Other areas included meadow spikemoss and horsetail.

Mud Lake (St. Joseph, LaPorte counties) contained sandy peat. Aquatic vegetation included Nuphar advena and Nelumbo lutea. Shallow wetlands contained Geum rivale and mermaid weed.

Shoreline fens and bogs would tremble the trees when humans walked across them. Known locally as grass and sedge deposits, these peat rafts were common in northern forest wetlands and southeastern conifer forests. These floating mats provided critical nesting habitat for birds such as the pied-billed grebe.

Emerging sand ridges formed islands ranging , and rising above the wetlands. Islands lacked deep organic muck, resulting in stable, mineral-rich soils, and supported Fox grapes, wild plum, and star-flowered Solomon's seal. Localized acidic patches supported acid-tolerant (ericaceuous) plants.

Birch lined the Kankakee River. Hardwoods prevailed where tamarack was rare. Bluejoint grass, quaking aspen, buttonbush and other species were abundant.

Cedar Lake (Lake County) was surrounded by fish-rich marshes and shrubs. Beaver Lake (Newton County) rested on sand, gravel, and blue till extending above bedrock. It measured long and wide and deep. Its beach lines rose above the landscape. It was covered by of water.

Bogus Island, in Beaver Lake's center, was covered with black cherry, and the surrounding marshes and ridges consisted of oak groves and prickly pear cacti.

During the 19th and 20th centuries, Late Pleistocene and early Holocene fossils discovered in the marsh included deer, elk, United-horn muskox, horse, and mastodon. Muck, marl, and peat deposits preserved fossils of the extinct stag-moose. In 1870, mastodon and muskox fossils were reportedly discovered during the draining of Beaver Lake. Mastodon fossils were found in the 19th century within the Kankakee Marsh in Porter County, near Hebron and Kouts. Other notable fossils included woolly mammoth and giant beaver. Giant beavers were the marsh's ecosystem engineers until their extinction 10,000 YBP.

Historic mammals observed in the marsh included coyote, Great Plains wolf, cougar, bobcat, gopher, beaver, muskrat, porcupine, and buffalo. Elk populations dwindled by the early 19th century. American red squirrels, eastern meadow voles, and prairie cottontails were common in the early 20th century.

Bass Lake (Starke County) was home to shortnose gar and Eastern box turtle. Archaeological sites confirm the kinds of wildlife Indigenous peoples hunted for food, which included modern reptiles (e.g., Blanding's turtle), amphibians (e.g., American toad), fish (e.g., longnose gar), and mollusks (e.g., purple wartyback).

Mollusks indicated healthy ecosystems in the marsh. In 1899, 63 different mollusk species were identified by geologists. Snails included Stagnicola reflexa and Lymnaea stagnalis. Clams included Sphaerium and Pisidium. Mussels included Plagiola elegans and Lampsilis alatus.

Burrowing crayfish aerated wetland soils and cycled nutrients underground. The marsh's abundant fish species included green sunfish, rock bass, and warmouth. Insects included striped sedge grasshopper and oblong leaf-winged katydid. Insects were a key food source for birds in the marsh, such as hawks, terns, rails, and bitterns.

Nineteenth century historians, naturalists, and hunters recorded over 225 bird species in the marsh, including permanent residents, seasonal visitors, and migratory birds. They included the prothonotary warbler, the most abundant summer species. Common species included large swarms of red-winged blackbird in grassy marshes, American golden plover in wet meadows, killdeer in dry prairies, Wilson's phalarope in marshes, American woodcock in open and forested bogs, and also American white ibis, whooping crane, and king rail. Prairie chickens bred in the wide, grassy wetlands. Black terns were summer residents. Merganser, duck, wigeon, mallard, teal, and other waterfowl also resided in the marsh. Goldeneye and Canadian geese would remain in the marsh during winter. Yellowlegs visited the marsh during migration from their South American non-breeding sites. Wetlands such as English Lake nourished waterfowl with acorns, wild rice, and smartweed, among other marsh roots and grasses. Birds of prey, such as the bald eagle, lived regularly within the marsh and English Lake.

One of the most notable animals of the Kankakee Marsh was the passenger pigeon, which would block out the sun when they flew in flocks. One account recalled the species flying over Lake County, describing millions of birds foraging in woods and fields, and flying at all heights, darkening the sky "as if an eclipse were on."

Human history of the marsh

Indigenous nations of the Kankakee region

Studies suggest the peopling of the Americas began 30,000 years Before Present (YBP). Evidence suggests the first Indigenous peoples (Paleo-Indians) existed in northern Ohio 13,738–13,435 calibrated YBP, and Clovis culture existed in southwest Michigan 13,000 YBP. Indiana's archaeological history dates to 10,400 YBP. The Collier Lodge site near the Kankakee River, in Porter and Jasper counties, contains artifacts spanning the last 11,000 years.

The history of Indigenous peoples (Native Americans, American Indians) in northern Indiana is marked by dramatic shifts in ecology and climate during the Late Pleistocene and early Holocene. Following the Younger Dryas, the warming period 10,800–10,000 YBP triggered conifer forests to transition to deciduous forests. Indigenous peoples migrated to wetlands created from drained proglacial lakes for more consistent resources. Indigenous peoples hunted between the Great Black Swamp in northeastern Indiana, and the Grand Kankakee Marsh. By 8,000–1,000 YBP, modern climate values prevailed in correlation with the rise of contemporary flora and fauna, followed by a drier period 6,000–2,000 B.C.E. which led to the establishment of prairie-based Indigenous communities.

The Kankakee Marsh offered hunting and fishing, opportunities for villages, and protection from enemies. Archaeological evidence in middens reveal pottery, arrow points, and the bones of animals Indigenous people consumed (e.g., fish, turtle, deer, beaver, birds, bears). Scientists suggest these sites could represent an early stage of Iroquois culture. The Griesmer site in Lake County by the Kankakee River contains artifacts from 2,100 years B.C.E.–1,500 C.E., placing it between the Late Archaic and the Post-classic or Protohistoric stages.

The Kankakee Marsh was home to the Kaskaskia, Kickapoo, Lenape, Mascouten, Meškwahki·aša·hina (Fox), Peoria, Piankeshaw, Potawatomi, Shawnee, Sioux, Wea, and Miami. The Miami trace their origins to the mouth of the St. Joseph River in Lake Michigan, called Saakiiweeyonki, the "Coming Out Place". Languages consisted of Eastern Algonquian, Central Algonquian, and Sioux; Oneota peoples engaged with Algonquian speakers in the marsh, such as the Sauk and Menominee. Mohicans lived on islands in the marsh in 1721. The Potawatomi, the "people of the place of the fire", were the region's majority, maintaining close cultural and linguistic ties to the Ojibwe (Chippewa) and the Ottawa. They burned soil for managing plants and crops, similar to modern burns. The Iroquois challenged the region's Indigenous groups, eventually leading to the Potawatomi siding with the French, and the Iroquois siding with the British during colonization.

The Potawatomi utilized the Kankakee River as a primary transit corridor, employing sophisticated birchbark canoes for navigation. Birchbark canoes were engineered for speed and durability, featured frames of birch, elm, hickory, or basswood, and came in various designs for use in specific bodies of water, from calm lakes to fast-moving rivers. According to Smithsonian historians Edwin Adney and Howard Chapelle, the canoes' advanced design and engineering skills showed "a long period of development must have taken place" before European contact.

Other modes of transport included horses and sleds. Horses were their primary domestic animal; they had no need for livestock as they fished and hunted game within the marsh. They also used ponies for travel.

Potawatomi villages and hunting grounds encompassed the Kankakee region. Diets from the marsh's vegetation included seasonal fruits and nuts, and maple sugar, while corn was cultivated in fields fertilized with pulverized fish and manure. One of their largest corn fields was located in present-day Wheatfield Township. Game included small mammals (e.g., rabbits, beaver, muskrat), large mammals (e.g., elk, bears, deer, bison), birds (e.g., turkey, prairie chicken, waterfowl), and fish (e.g., pike, bass, sunfish). Navigating the Kankakee Marsh developed the Indigenous peoples' wayfinding skills and deep ecological knowledge.

The Ojibwe and the Anishinaabe harvested wild rice, which they called manoomin, and viewed it as a sacred, important part of their identity, livelihood, religion, culture, and traditions. Substantial wild rice beds existed along the Kankakee River and in Beaver Lake, which was known in the Potawatomi language as Sag-a-yi-gan-nik-youg, or "Lake of the Beavers". Beaver Lake's archaeological sites yield weapons, tools, ceramics, and village sites.

Indigenous peoples used sandy, elevated ridges as high-ground islands for settlement, defense, and burial. Red Oak Island (LaPorte County) and Big White Oak Island (Lake County) could hold hundreds of people. Jackson's Island, or Indian Hill, was a prominent ridge until 19th-century drainage; the site is now adjacent to the Starke County Airport. The islands also provided security; for example, Curve Island near Shelby was fortified with defensive trenches during conflicts between Indigenous nations.

Ridges were also culturally significant burial sites, with some graves dating back 2,000 years. Indigenous people would bury the dead with funerary objects (e.g., weapons, ornaments, tools), and occasionally their dogs. Graves ran in rows, and sometimes covered with small, house-like structures. In a Kankakee tributary in LaPorte County, several burial mounds measured in height. The presence of shells in these graves indicates extensive regional trade networks and evolving inter-cultural relationships.

Villages featured council houses, dance grounds, and agricultural fields. People lived in wigwams around a village center reserved for ceremonies. Common possessions included breast plates, crosses, and ceremonial pipes.

First contact with 17th-century Europeans in the Kankakee Marsh included French explorers and Jesuit missionaries. Indigenous peoples, followed by French colonialists, British colonialists, and American settlers, influenced the Kankakee River's name. Some historians linked the original name — recorded as Thea-kiki, Huakiki, or Kankekiki — to "the land inhabited by wolves and river", with The-Ak (meaning wolf) and A-Ki (meaning land). Conversely, others interpret it as Ti-yar-ac-ke, meaning "wonderful land" in Potawatomi. In 1679, La Salle recorded the name as Teakiki. French explorers later modified it to Quin-que-que, which British explorers anglicized to Kankakee. There are at least 19 historical spellings of the name.

The Kankakee Marsh served as the hunting grounds for regional forts and traders. Encounters between Indigenous peoples and Europeans during marsh hunts were often non-violent and mutually respectful.

The North American fur trade, the Beaver Wars, and the French and Indian War fundamentally altered relations between Indigenous peoples and Europeans. Pontiac's War, the American Revolutionary War, and the Northwest Indian War foreshadowed both the total destruction of the Grand Kankakee Marsh and the forced removals of Indigenous peoples. Modern historians continue to debate whether these actions constitute ethnic cleansing or genocide.

During the late-18th century wars, wildlife populations grew while men fought each other in battlefields; hunters in the Kankakee region noted an abundance of game in 1790, following lower numbers in previous years.

Indigenous removals and treaties for the marsh

The 1787 establishment of the Northwest Territory by the U.S. Congress initiated profound changes for the Indigenous peoples of the Kankakee Marsh. Following the U.S. victory in the Northwest Indian War, the federal government systematically acquired Indigenous lands across the Midwest through a series of forced treaties.

During the 1811 Battle of Tippecanoe, the Kankakee Marsh sheltered Indigenous women, children, the sick, and the elderly. The War of 1812 proved a turning point, with the Indigenous peoples defending key sites along the Kankakee and Yellow rivers. Following the decline of British influence post-1812, the Pottawatomi moved toward peace with the U.S. government. By the 1820s, however, encroaching American settlements increasingly undermined the traditional hunting and trapping economies of Indigenous peoples.

Indian removals in Indiana began in the 1790s through government treaties. The Kankakee Marsh was acquired via five specific treaties. The first was the 1821 Treaty of Chicago (Cession 117), which forced the Ottawa, Chippewa, and Potawatomi to cede headwaters near South Bend and the St. Joseph River. The second was the 1826 Treaty of Mississinewa (Cession 133), in which the Potawatomi ceded the remaining marsh's headwaters.

Small numbers of settlers had reached the Kankakee region by 1830, the year the Indian Removal Act codified the forced displacement of Indigenous peoples. Settlement was delayed for two years by the 1832 Black Hawk War, followed by a large influx of settlers in the region.

Further treaty negotiations led to additional forced relocations of the Potawatomi in northeastern Illinois. This resulted in the third treaty for the region: the October 20, 1832 Treaty with the Potawatomi, Prairie, and Kankakee Band (Cession 177), which ceded the Kankakee Marsh in Illinois. The fourth treaty, the October 26, 1832 Treaty of Tippecanoe (Cession 180), ceded the entire Kankakee Marsh region across northern Indiana. The removal of the Potawatomi from the Kankakee region between 1833 and 1834 severely crippled the regional fur trade.

The Potawatomi remained within the Yellow River headwaters until April 1836, when treaties ceded the Lake Maxinkuckee lands. The final treaty for the Kankakee Marsh region (Cession 218, signed on August 5, 1836) ceded the Yellow River's headwaters and the site of modern-day Plymouth. Additional treaties followed in September 1836 covering the neighboring Tippecanoe River headwaters.

The genocide of Indigenous peoples (American Indians, Native Americans) is often minimized by the denials of such human atrocities. Settler colonialism's eliminatory dynamic was driven by the desire to acquire land and resources, and by anti-Indigenous racism that portrayed Indigenous people as "inferior" and as obstacles to conquest. Although the term Manifest destiny was first used in 1845, the underlying ideas already existed in places like the Grand Kankakee Marsh region by the early 19th century. The 1830 Indian Removal Act enabled White settlers to continue the violent removal of Indigenous peoples from their lands.

Indigenous people were vulnerable to "land sharks", speculators anxious to purchase Indigenous territories including "floats", which were small pieces of land granted to the tribe through the treaties. These speculators would buy up these floats, then sell them to settlers at higher prices throughout the Kankakee region.

Small groups of Indigenous people remained in the Kankakee Marsh by 1835. The 1838 Potawatomi Trail of Death occurred when American militia forced remaining Potawatomi bands out of Indiana at gunpoint, marching them to Missouri and resulting in high mortality rates. Other bands were forced out as late as 1850.

Historians describe rare encounters with Indigenous people in the Kankakee region years after the removals.

Early settlements in the marsh

The Kankakee Marsh delayed development of the region. Prospective settlers were also discouraged by the economic depression of the 1830s. The Indiana legislature authorized the construction of roads leading from Indianapolis in 1821. However, the Kankakee Marsh blocked emigration from southern Indiana, obligating settlers to move around it through LaPorte and St. Joseph counties, or to move east to places like Allen County. During winter, people could cross the Kankakee Marsh and its rivers when it became frozen solid.

Historians described marsh settlers as "a class of people out of the ordinary," and "afraid of no one." They lived as hunters, fishers, and trappers. Myths emerged about the marsh, fueled by tales of criminals hiding in swamps or on islands, fossil discoveries during drainage, and dangerous muck. Bogus Island in Beaver Lake gained notoriety as a base for bandits, counterfeiters, and horse thieves between 1837 and 1858. Jasper County similarly earned a reputation for crime, as its swamps provided refuge for the "Bandits on the Prairie". In 1858, the county organized "The Jasper Rangers" to apprehend these outlaws and enforce the law.

The Land Act of 1820, pricing land at $1.25 per acre, accelerated settlements in the Kankakee region. Before 1832, the population consisted primarily of fur traders and trappers. The Michigan Road facilitated migration to the Kankakee region. Despite the challenging wetland terrain, land surveys by the General Land Office (GLO) were completed around 1830, with "claim seekers" arriving in Lake County by 1834, well before official sales commenced in 1839.

Researchers now use historical land surveys to create GIS-based presettlement vegetation maps, allowing for the study of lost ecosystems. While Indiana's current map provides a generalized overview of historical plant communities, it lacks the detailed vegetation descriptions found in similar maps from other Midwestern states and cities.

Settlers initially utilized the marsh for livestock, incentivized by county bounties for wolf scalps throughout the 1840s. Homes were established on sand ridges, with "ditch fences" (shallow trenches) serving to drain wetlands and delineate property. Early settlers cultivated cranberries. Trading posts along the Kankakee River sold customers farming and hunting supplies. Farmers fertilized land by mixing lowland muck with sand, bone meal, or slaughterhouse waste.

Early 19th-century settlers relied on the land for survival due to limited transportation. Deforestation followed as they harvested fuel and timber from the marsh's islands. Settlers also utilized local aquifers; mineral springs were highly valued for treating conditions such as indigestion and kidney ailments.

By the 1830s, local iron works utilized marsh-extracted bog iron, while marl lime supported regional construction. Sawmills and grain mills were established in 1836. Railroads reached Kankakee County by 1850, expanding significantly throughout the 1860s.

Early settlers migrated to the Kankakee Marsh from southern Indiana and Ohio, followed by a diverse influx of immigrants from across Europe, including Germany, Italy, Poland, Sweden, and Bohemia. After Starke County's 1850 organization, the population grew with settlers from Pennsylvania and Illinois alongside additional groups from the British Isles, Russia, and the Netherlands. Various denominations, including Baptists, Presbyterians, Catholics, and Methodists, established congregations by the 1830s, forming the core of the region's expanding towns and villages by the 1870s.

Black settlers entered Indiana in the early 19th century. Although Indiana was not a slave state, they still faced discrimination. They had to register with local authorities, prove they were not fugitive slaves, and pay a $500 bond for good behavior, among other legal limitations. Such was the case of William Greenwood when he became a citizen of Kankakee Township, LaPorte County, in 1834.

Several successful Black farming communities emerged in the Kankakee Marsh region. They included the Henderson Settlement, located near Fish Lake, Mud Lake, and the northern part of the marsh in Lincoln Township. It was home to Black families from Virginia who settled there in the 1840s, and their farms produced high yields from cattle and corn. Nearby was the Banks Settlement in Center Township, which also thrived. In St. Joseph County, the Huggart Settlement was home to a Black farming community which was established in the 1830s near the marsh, next to what is now Potato Creek State Park.

The Underground Railroad and the Grand Kankakee Marsh

The Underground Railroad in Indiana operated near the Grand Kankakee Marsh, leveraging the difficult terrain to assist freedom seekers traveling toward Canada. Historian W. Sherman Savage documented a stop in North Judson, situated within the marsh, just south of English Lake. Wilbur H. Siebert also studied Underground Railroad sites across the Kankakee region. Other documented stops reached by crossing the marsh were Rensselaer (Jasper County), Hurlburt (Porter County), and the Low Cemetery in Coolspring Township (LaPorte County), with the latter being officially landmarked as part of the "Chicago-to-Detroit Freedom Trail." To avoid detection, the clandestine locations for the Railroad frequently shifted.

Slaves used every precaution to evade recapture by slave catchers, including hiding in wetlands. Before runaway slaves reached the Kankakee Marsh to hide, they had already accumulated experience hiding in other wetlands. They included Deming's Dismal Swamp, Attica's swamps, and Marion County's swamps and marshes where abolitionist Quakers led slaves to freedom.

Although most of Indiana's White population opposed the Underground Railroad, its operators included White people, particularly Quakers such as Levi Coffin. White people worked with Black people to free slaves for religious reasons, and also for resisting the encroachments of slave hunters on their lands. In 1849, hundreds of armed men from Michigan liberated a group of recaptured slaves in South Bend near the Kankakee Marsh's headwaters. The Black community of Hopkins Park (Kankakee County, IL) sheltered fugitive slaves seeking freedom in Canada. Pembroke Township later established a large black population. Indiana operators and agents in the Underground Railroad helped slaves at the risk of being punished by the state. The Fugitive Slave Act of 1850 further imposed strict penalties.

Unconfirmed accounts of Underground Railroad stops and hiding places within the Kankakee Marsh include slaves hiding on Bogus Island in Beaver Lake. A small Black farming community later developed in McClellan Township within the drained Beaver Lake by 1870. Lost Lake reportedly concealed slaves within the Kankakee Marsh. Unlike other wetlands such as the former Great Black Swamp (in Indiana, Ohio, and Michigan) or the Great Dismal Swamp (in North Carolina and Virginia), the former Grand Kankakee Marsh does not currently have Underground Railroad sites recognized by the National Park Service's Network to Freedom program.

Early drainage efforts

Settlement in the Kankakee Marsh grew throughout the 19th century, though wetland conditions obligated settlers to build on higher ground. Farmers struggled to drain wetlands due to inadequate technology and the absence of organized drainage laws. The federal government passed the Swamp Land Act of 1850, donating wetlands to states for development and setting a sale price of $1.25 per acre. In May 1852, the Indiana State Legislature began regulating the sales of wetlands and providing grants for drainage and land reclamation.

Each county appointed a swamp land commissioner to oversee reclamation with engineers. Steam dredges excavated ditches typically wide and deep. In 1852, the Indiana State Board of Agriculture proposed state-funded drainage of the Kankakee Marsh by canalizing the river to increase property values and tax revenue. Initial efforts relied on rudimentary lateral ditches and tile drains, often obstructed by beaver dams. Early reclamation strategies also utilized widespread deforestation to increase evaporation by exposing wetlands to sunlight.

In 1853, initial state efforts to drain the Beaver Lake, until Lemuel Milk successfully drained the lake for farming. By 1877, investors from Chicago and Cincinnati financed the conversion of these former wetlands into corn fields and cattle pastures. One observer of this transformation famously remarked, "They murdered this land while they were at it, and made a good job of it!"

In March 1854, Kankakee County became an early recipient of Kankakee Marsh lands under the Swamp Land Act of 1850. Its drainage commissioner sold wetlands at a fixed $1.25 per acre exclusively to actual settlers, while other counties were selling large tracts to speculators for lump sums. Widespread fraud plagued government-funded ditch construction, as commissioners colluded with contractors to misappropriate funds, leaving much of the marsh undeveloped. An 1859 Legislative Committee confirmed significant theft, including over $40,000 in state-level losses and more than $100,000 in Lake County alone, where less than half the allocated money actually funded drainage. The state failed to recover the assets.

In 1869, Indiana enacted the Kankakee Drainage Law to facilitate wetland reclamation. The Kankakee Valley Draining Company formed that same year but dissolved after legal challenges from landowners protesting its power to levy assessments. In 1871, the state issued millions in bonds to fund further drainage. Ongoing litigation stalled progress until 1881, when the Indiana General Assembly authorized a formal survey to determine a viable path forward.

Geologist John L. Campbell advocated for professional engineering to accelerate drainage. Another geologist criticized the state's lack of initiative, arguing that the marsh, viewed as a "vast waste" inhabited only by wildlife, should be transformed into a productive "garden spot" through systematic drainage.

"The march of evil": Public health issues in the marsh

Misunderstandings and fallacies about wetlands were used to promote agricultural interests, even as scientific knowledge was advancing and becoming publicly available. In the 1860s, the agricultural community considered wetlands as "evil". Robert Clark Kedzie, author of Shadows from the Walls of Death and a physician in support of drainage, described the "water-soaked soils" of wetlands as "The march of evil". The agricultural community also viewed apex predators as "evil", and encouraged their extermination.

Public fear of diseases like malaria drove wetland destruction. Scientist John Merle Coulter embraced miasma theory in 1881, arguing that wetlands would "poison the air" unless they were drained for farming. Settlers were unaware drainage ditches created mosquito breeding grounds, or that temperature and rainfall were primary risk factors for malarial infections by mosquitoes. By 1880, the scientific consensus regarding malaria transmission began to gain acceptance in Indiana.

Indigenous populations suffered significant losses not from the marsh they had lived with for over 13,000 years, but from disease endemics newly introduced by European and American settlers. Diseases like smallpox decimated Indigenous communities, killing an estimated 90% of all Indigenous peoples across the Western Hemisphere. European germ warfare also caused Indigenous population declines.

Epidemics such as cholera are primarily driven by inadequate human hygiene and sanitation. However, many Indiana physicians falsely asserted that draining the Kankakee Marsh would improve public health "a hundred-fold," prioritizing land reclamation over genuine sanitary reform. By the early 1900s, the adoption of modern sanitation standards began to replace outdated beliefs, leading to genuine improvements in public health.

"A hunters' and trappers' paradise": recreational hunting and fishing in the marsh

By the mid- to late-19th century, the Kankakee Marsh gained international renown as a premier hunting destination, drawing enthusiasts from across the U.S. and Europe. Often described as a "hunters' and trappers' paradise," the region hosted vast populations of migratory waterfowl, including ducks, geese, snipe, and plover.

Kankakee Marsh gun clubs included the Chicago-based English Lake Gun Club and Starke County's Maksawba Club, where members hunted diverse game like duck, snipe, rail, woodcock, quail, grouse, and rabbit, and fished for pike and bass. The Diana Club, located on the Indiana portion of the river, hosted organized medal contests for live-bird shooting. Hunters were accompanied by "pushers" (skillful assistants) from these clubs. Some hunters harvested rabbits in the marsh to supply food to Chicago's unemployed.

Gun clubs held charter memberships focused on socializing and marksmanship, with daily individual tallies reaching 300 birds daily per person. Hunters could claim up to 80 deer in a single day; some used muzzleloaders.

The introduction of the breechloader increased hunting efficiency, facilitating the rapid slaughter of wildlife. Shooting accidents became common, and the Kankakee's dense forested swamps gained a reputation for danger, with reports of men and hunting dogs disappearing. Two hunters drowned in the river's treacherous meander known as the "Devil's Elbow."

Trains transported Chicago-based hunters directly to the Kankakee Marsh and its private clubs. Out-of-state hunters paid a $25 license fee for access. While the Toleston Club, near the Illinois border, implemented a 25-bird daily limit, hunting remained intense. Many constructed seasonal shelters, while others utilized local hotels or commuted via the Indiana, Illinois and Iowa Railroad, often staying at locations like the Hotel Riverview in Kankakee. Famous people hunted and fished in the marsh, including Lew Wallace, author of .

The Kankakee River attracted sportsmen targeting muskellunge, bass, crappies, perch, pickerel, and catfish. The introduction of European carp disrupted this ecosystem; their tendency to overrun rivers and muddy clear streams led anglers to label them a nuisance that "ruined" the river. Carp were dynamited in large numbers with brutal efficiency.

In 1898, the Illinois Fish Commission released 10,000 native bass into the Kankakee River to boost local populations. Anglers frequently visited the "sluggish" waters below Momence, with groups like the Chicago Fly Casting Club targeting bass. At Starke County's Maksawba Club, enthusiasts routinely caught 15 to 35 bass per day using frog bait. Records were always being broken for who caught the most fish.

Initially regarded as a "garden of Eden," the Kankakee Marsh was rebranded the "Garden of Chicago" by 1911 as settlers began draining the wetlands for agriculture. "Timber thieves" decimated regional forests, prompting landowners to organize enforcement posses against illegal logging. Bog iron fueled railroads, iron mills, smelting, while local lime and sandstone were quarried for construction.

Unregulated hunting and fishing devastated the marsh's wildlife; local restaurants routinely served illegal game. Such pressures prompted the hiring of game wardens at Momence. Large hunting parties with dogs decimated bird populations; incidents included the shooting of a bald eagle near Roselawn and the death of a goose that had previously survived being impaled by an arrow in the Yukon.

Porcupine, otter and coyote populations were locally exterminated. Commercial demand for game included pigeon, frog, and turtle. Bullfrogs were exported to other states for market. In 1883, an entrepreneur in North Judson commercially exported 35 tons of frogs and hundreds of turtles to markets and universities.

Expanded railroad networks facilitated this exploitation, enabling the rapid shipment of game and timber. Deforestation exhausted local building materials. By 1889, Railroad Township joined a statewide oil supply network. Railroads supplied resources for Chicago.

Telegraphs provided hunters real-time intelligence from English Lake and local bayous, optimizing the tracking and hunting of prize birds. Chicago mills profited from egret plumes sourced in the Kankakee. Despite market value for crane plumes in women's hats, hunters slaughtered 60 to 80 Great Blue Herons daily at "Crane Heaven" near English Lake, often discarding the carcasses where they fell on the ground.

In one day, 1,300 ducks were killed within a 200-square-yard area, prompting local media to report, "This is how the ducks are being destroyed." Forest and Stream editors documented daily tallies of 100 birds per hunter, warning: "If this will not exterminate game, for goodness sake what will?"

Commercial hunting for fur and pelts thrived in the Kankakee Marsh and at Beaver Lake. On Fuller Island near Shelby, single hunts yielded large wagons filled with thousands of dead rabbits, while the region's muskrat and long-tailed weasel populations faced intense annual trapping.

In March 1879, Indiana protected native fish populations, yet concurrently passed laws enabling wetland drainage without habitat safeguards. Despite proposals to repurpose wetlands for fish culture, large-scale drainage prioritized agricultural expansion.

Distrusting Indiana politicians to enforce anti-trespassing laws, hunting clubs and private landowners hired their own security. By the 1890s, residents lobbied for protected areas and wardens. The Kankakee Fish and Game Protection Association formed in 1891, using fines to curb lawlessness while supporting commercial interests. Deer populations collapsed statewide except in the Kankakee Marsh. Impending river channelization would further accelerate wildlife extirpation.

Draining the marsh

Channelization, 1882–1917

In 1882, Dr. John Campbell published a report formalizing strategies to drain the Kankakee Marsh. These plans built on concepts circulating since the 1850s, specifically the removal of a limestone ledge at Momence that constrained river flow. In 1883, the Kankakee Draining Company identified for reclamation, projecting $8–10 million in agricultural profit.

The Kankakee Draining Company proposed a new river channel measuring wide at the top, wide at the bottom, about deep, and inclined at . This would increase the water's velocity to and its discharge volume to . The new river would be divided in seven sections, with each channel section consisting of different sizes and a network of ditches to drain the marsh. In 1885, Campbell testified that this project would truncate the river from to , but indicated ongoing maintenance was essential, noting, "a straight channel tends continually to become crooked."

In the 1880s, the Indiana Legislature empowered drainage districts to levy taxes for reclamation. Under this system, landowners petitioned for state surveys and bond issues to fund construction. Although modest ditching began in the 1850s, the Kankakee Marsh west of Marshall County remained largely intact due to the lack of a sufficient outlet. To overcome this, a massive, systematic channelization project launched in 1884, utilizing steam-powered dredgers to restructure the landscape.

In 1886, the Indiana State Board of Agriculture adopted Campbell's report, prompting congressional efforts to secure federal funding for drainage at Momence. By 1887, two steam dredges began excavating, initiating the systematic drainage of the marsh. Business interests lobbied the Indiana General Assembly for state-funded, large-scale drainage by canalizing the Momence rock ledge. Drainage investors advanced steam dredging technology.

While Forest and Stream initially downplayed the threat of the draining of the marsh, economic pressure intensified; the Indiana State Board of Agriculture projected land values would jump from $4 to $30 per acre upon drainage.

On March 7, 1889, the Indiana General Assembly appropriated $65,000 to remove the limestone ledge, with follow-up funding in 1891 and 1893. Paralleling Illinois's 1879 Drainage Levee and Farm Drainage Acts, Indiana passed legislation in 1889 enabling the formation of drainage districts to pool resources for further marsh destruction.

When ditches failed to fully drain the fields, they were abandoned and unintentionally became boatways for hunters. Ditches also became county and property boundaries.

Historians and the public often mischaracterize the Momence Township, Illinois rock ledge as a removable dam responsible for impounding the Grand Kankakee Marsh. In reality, it is a stretch of exposed natural bedrock over which the river flows. Before its alteration, this reach was prized for fishing.

Indiana sought to drain the Kankakee Marsh by removing the limestone ledge located into Illinois. Delays in financing the project continued through the late 1880s. In 1891, the Indiana Legislature authorized a board to oversee the removal of an estimated 68,819 cubic yards of rock, allocating $60,000. The project faced potential legal friction, with officials concerned that Illinois might block crews from crossing state lines to perform the blasting. The rock was partially destroyed by the project in 1893, which created a channel long, wide. The bedrock outcropping was lowered by to increase the speed of water flow, despite some boulders preventing total drainage. Aggressive channelization and drainage soon followed with steam dredges.

To accelerate drainage, massive arterial ditches were constructed alongside the new Kankakee channel. Key projects included the Singleton Ditch in Lake County, as well as the Breyfogle, Cornell, and Robbens ditches. By 1888, Lake County contained of ditches. While the marsh's natural elevation dropped only , ditches were engineered with slopes of to gravity-drain surface water.

By 1897, most of the eastern Kankakee Marsh was drained. Lead engineer John L. Campbell and investors dismissed project costs as "insignificant" compared to the benefits, fueling a land-buying frenzy such as the La Crosse Land Company's $165,000 purchase of . Developers and settlers raced to drain the marsh. By 1897, about of wetlands remained in Porter County. However, rapid drainage and deforestation degraded local forests, fruit crops, and soil fertility. Farmers realized how over-excessive ditching and deforestation was harming the soil's ability to renew itself naturally. Dredgers and speculators clashed with farmers and locals in what businessmen described as a battle of "ignorance and prejudice" versus "brains and capital."

The Indiana General Assembly allocated $2.5 million to develop the land. By 1898, steam-powered drainage had transformed wetlands into farmland valued at $5 to $300 per acre, facilitated by rail access. Investors utilized tenant farmers and intensive tiling to exploit the soil, actively targeting the richest marshlands for drainage.

The size and scale of the dredged channels increased as the river flowed west past Kouts and Hebron. Drainage raised land values near Shelby to $150 per acre by 1922. The "land poor", people who had bought wetlands at low prices in the mid-19th century, profited from drainage decades later.

Kankakee River channelization concluded in 1917 at the Indiana border; the river was never channelized in Illinois. This $1.2 million project, funded by local land assessments, shortened the river from to , eliminating all wetlands. In 1927, the final removal of the Momence boulders accelerated water flow, turning the river into a high-velocity sluice transporting heavy sand loads from Indiana into the original meanders of the Illinois reach. The old river meanders became disconnected oxbow ponds or dried up.

Forest and Stream eulogized these changes, stating:

Fate of the environment

Mid-19th century Indiana did not view the draining of the Grand Kankakee Marsh as resource depletion, environmental degradation, biodiversity loss, or ecosystem collapse. They instead viewed it as the "redeeming" of "unimproved" lands for human use. Examples of what they considered "improved lands" included crops, orchards, buildings, and stock farms.

The 1851 State Board of Agriculture had aimed to emulate European drainage models, reframing wetlands as agricultural assets. By 1911, steam-powered dredging had converted the landscape into a grid of ditches, creating a strong agricultural economy. Land values surged from $2 per acre as wetlands to $40–$75 as cornfields. Drainage was framed as an economic improvement. Drainage was also framed as a moral imperative to impose "law and order" on a region known to harbor fugitives, horse thieves, and counterfeiters.

While many in 1925 celebrated the project as a success, others lamented the loss of a premier North American bird refuge. Proponents dismissed dissenters as "ignorant," prioritizing short-term profit over ecological preservation. One proponent noted, "Forests were to be felled, cabins erected, mills built and the rivers and creeks made to labor for the benefit of mankind."

In contrast, another historian noted how utilitarianism influenced the marsh's destruction, stating:

Scholars have argued utilitarian mindsets often struggle to account for empathy or conservation. Similar to utilitarianism, extractivism in the 19th and early 20th centuries focused on maximum wealth and utility, but caused environmental and human rights abuses worldwide. In the U.S., Manifest Destiny asserted that uncultivated Indigenous lands were being "wasted", in order to justify the seizure and farming of those territories. These prevailing mindsets dismissed wetlands as "wastelands", justifying their destruction for maximum economic utility.

Swamps in Starke County were deemed "worthless" by settlers. In Lake County, Cedar Lake's marshes were deemed "worthless" and were drained with a ditch, which lowered lake water levels and reduced its groundwater supply. The marsh in St. Joseph County was deemed "utterly useless" until it was drained for farming. Wetlands were called "bogus places" if the soils were too saturated and required deeper tile drainage for farming.

Forest and Stream reported that the "main ditch", formerly the Kankakee River, contained no bass, and, observing cornfields where wetlands once stood, declared that "the glory of the Kankakee has assuredly departed." The publication noted ditching financially crippled hunting clubs. By 1904, while quail remained, prairie chickens had become scarce. Hunters cited drainage as the primary driver of wildlife displacement. One hunter stated, "drainage has been the most potent factor in driving the birds away." By 1897, wild rice became scarce across the region. When game became scarce, hunters pursued other business ventures to earn a living.

Hunters persisted near Momence, reporting to Forest and Stream the rest of the region was "ruined" and "as dry as a bone." Draining eliminated bird nesting sites, altered migratory patterns, and caused wetlands to become "dry and dusty." As jacksnipe declined, plover prevailed in drained areas.

Frequent floods prevented successful farming in certain areas. Undersized channels were widened to accommodate more water. Drainage impacts are constantly monitored. Failed drainage exposed former wetlands to severe erosion, creating localized deserts.

Extensive drainage in certain areas has failed to prevent flooding, which occurs several times each year. Excess sediment is dredged in the Kankakee River at the Illinois border, despite agricultural drainage issues created by Indiana which harm aquatic habitats and cause floods. Mitigation of flood damage includes deepening ditches and implementing flood insurance programs for farmers.

Draining wet prairies exposed peat, creating significant fire hazards as the material dried and reduced to ash. These fires were often misattributed to drought, despite suspicions of arson. High winds frequently fanned flames that ignited trapped gases, burning as deep as into the ground. Hunting clubs lost land to fires. By 1895, these persistent blazes had decimated local American egret populations, due to the draining of peat-based landscapes.

By 1926, the Indiana Department of Conservation criticized the "chase after the almighty dollar" that sacrificed the state's natural legacy.

Economic and population growth

By 1911, drained wetlands and "muck" farms were valued at $150 per acre. Despite high valuations, peat and muck soils lost productivity annually, requiring fertilizers and manure. Drainage also increased drought vulnerability. Vegetation was harvested for hay, and crops were matched to different soils. Land value varied by soil quality; Maumee loamy fine sand and Maumee silty clay loam were highly valued, while acidic Newton fine sandy loam was less suitable for certain crops. Island ridges were deforested for timber and farming, though drifting sand reduced their agricultural utility.

Crop irrigation was required in certain areas due to drought risk and access to groundwater. However, excessive irrigation pumping has led to water level declines, impacting soil health and crop productivity. Sod farms in Jasper and Lake counties also use excessive irrigation, impacting local water levels.

Drainage of the Yellow River marshes exposed former sand ridge islands to wind erosion, revealing Indigenous artifacts. Deforested ridges were repurposed for grazing, and new agricultural settlements and livestock farms emerged, such as the town near English Lake. Homesteading often involved speculation, with buyers acquiring cedar swamps to liquidate them for timber.

Railroad construction across the reclaimed Kankakee basin required constant gravel reinforcement to stabilize sinking marshland. Excavation revealed peat deposits up to deep, which were harvested for fuel. Expanding rail networks — including the Pittsburgh, Cincinnati, Chicago, and St. Louis, and the Chesapeake and Ohio — linked the basin to national markets. Following the 1916 discovery of oil and gas near Thayer, pipelines were laid across the former English Lake floor to connect refineries to ports. This prompted widespread fraud, as shell companies sold fraudulent extraction shares to investors in Jasper and Pulaski counties.

Factories within the rail network utilized submerged clay for brick and tile production. Clays and chalks near South Bend were processed into Portland cement. Peat and bog iron extraction fueled regional industry, including planned sugar beet factories in the Kankakee Valley. The Kankakee River supplied water to sugar beet factories, favored for its low calcium sulfate content. Water mills harnessed local stream power.

The 1920 U.S. Census recorded 16,950 farms across nine Kankakee Marsh counties, with a population of 425,668 and crop values totaling $53,391,150 (unadjusted). By 2022, the number of farms decreased to 4,652, while the population grew to 1,247,379 and the market value of non-animal agricultural products reached $1,669,470,000.

Restoring the marsh

River restoration

Beginning in the 1890s, the Kankakee Marsh suffered from excessive development. Hunters, noting declining wildlife post-drainage, demanded conservation. In the early 20th century, Illinois banned the sale of most wild game. Only remained under state control, later earmarked for conservation and recreation.

In 1923, of the former English Lake were acquired as a game preserve, though timber theft necessitated legal intervention. Later managed by the Division of Fish and Game as the Kankakee Fish and Wildlife Area, the preserve prohibited hunting but permitted fishing in boundary ditches. Unsuitable for agriculture, the land supported recovering populations of muskrats and prairie chickens, and planted with corn and buckwheat to sustain bird populations such as ring-necked pheasants. In 1936, the preserve added , creating a lake and marsh that bolstered waterfowl populations, including mallards, teal, and wood ducks. The preserve currently holds of habitat.

A second game preserve was established in Walker Township, south of the Kankakee River, on of marginal farmland.

During the Great Depression, the Works Progress Administration and the Civilian Conservation Corps expanded wetland preserves to increase aquatic vegetation and nesting grounds, aiming to restore historic migratory flyways. Wildlife protections included a ban on mussel harvesting in Kankakee River breeding grounds. The Division of Fish and Game stocked the river with native perch, bass, and bluegill to bolster populations.

Geologists advocated for reforestation to counteract increased soil evaporation caused by wetland drainage and deforestation. Since 1931, experts have studied restoring the Kankakee Marsh as a federal migratory bird refuge. In 1942, the Indiana Department of Conservation and the Izaak Walton League proposed a partial restoration of the Kankakee Marsh, but the plan was never fully implemented.

In the 1990s, the U.S. Fish and Wildlife Service (USFWS) proposed a refuge to restore the Kankakee Marsh by dismantling regional drainage systems. Local landowners opposed the project, citing concerns over lost tax revenue, farm drainage, and flooding. The Momence Board rejected the proposal in 1998, criticizing the agency's failure to address sedimentation, flood control, and drainage district conflicts.

The Kankakee County Board opposed a 2021 proposal for a refuge near Momence, Pembroke Township, and Hopkins Park. The board cited the loss of $1.2 million in annual property taxes, including $800,000 for the Momence School District.

Established in 2015, Lydick Bog is a nature preserve in St. Joseph County, containing a rare, intact sphagnum bog. While minerotrophic marshes dominated lower valley elevations, ombrotrophic peatlands like Lydick Bog developed at higher northeastern elevations of the Kankakee Marsh. It supports diverse flora, including winterberry, tamarack, cranberry, maple, oak forest, oak savanna, hickory, and carnivorous species like round-leaved sundew and pitcher plants. The preserve protects Lydick Bog as one of the last remaining sphagnum bog habitats in Indiana.

In May 2016, the USFWS established the Kankakee National Wildlife Refuge and Conservation Area in Iroquois County.

The Momence Wetlands Reach, the area between the Indiana border and Momence, Illinois, continues to experience overaccumulating sediment caused by the channelized river in Indiana, with the river moving and depositing sand at a faster rate than within the channel. In 2000, it was reported that the Kankakee River was discharging over 872,000 tons of sediment annually, depositing at the state line. This jeopardizes wildlife protection (including fish spawning habitat), flood control, drought prevention, water quality enhancement, and sediment control. It impairs the Momence Wetlands' natural functions, which provide an immeasurable public service and economic value for the region. Indiana and Illinois stakeholders are collaborating to mitigate siltation, nutrient runoff, and sedimentation near Momence while working to restore wetlands and mussel beds.

Organizations focused on reversing wildlife habitat loss include the The Nature Conservancy and the Indiana DNR in remnants of the former Kankakee Marsh in Newton and Lake counties. The area includes the Kankakee Sands, the Willow Slough Fish and Wildlife Area, the Conrad Savanna Nature Preserve, and the Conrad Station Savanna. Adjacent to the former Beaver Lake is the Iroquois County State Wildlife Area and its Hooper Branch Savanna Nature Preserve, containing of sand dunes, savannas, and wet prairies. Habitat loss studies have focused on all species, including reptiles and amphibians. Studies on aquatic insects, which are keystone species that support the food web, have revealed how wetland losses lead to significant declines in insect populations and diversity.

Indigenous peoples today

Indigenous peoples in the U.S. refer to themselves as American Indians or Native Americans, with preferred usage depending on the individual. Preferences include identifying by their nations: Potawatomi, Chippewa, and other groups who called the Kankakee Marsh region home, which shaped their languages and cultures for millennia. The Citizen Potawatomi Nation, the Peoria Tribe of Indians of Oklahoma, the Kickapoo Tribe in Kansas, and other nations that called the Grand Kankakee Marsh home continue to reside west of the Mississippi, where they were forced to move by the U.S. government in the 1830s.

Contemporary Indigenous identity is maintained despite a history of harmful federal policies, including the Dawes Act, the 1956 Indian Relocation Act, and the mismanagement of reservations. Indiana history books of the 19th and 20th centuries often utilized racist frameworks to document the region. Historical works frequently promoted the "Fire-Water Myth" within the Kankakee region. This genetic stereotype regarding alcohol susceptibility has been identified by the Substance Abuse and Mental Health Services Administration (SAMHSA) and other organizations and scientists as scientifically baseless. Timothy H. Ball and Marcus Ward Lyon Jr. applied the "Vanishing Indian" stereotype, distorting the history of the Indian Removal Act in the Kankakee region. In "Mammals of Indiana" (1936), Lyon Jr. further utilized scientific racism and eugenics to classify African-Americans as a "subspecies" and an "introduced" population, omitting the history of slavery and the Great Migration.

Indigenous graves were frequently desecrated by Kankakee Marsh farmers during soil cultivation. Plowing and bulldozing exposed and exhumed numerous burial mounds. Many archaeological sites and cemeteries were discovered when sand hills were leveled and bulldozed for farming. In Kankakee tributaries of Porter, Lake, and LaPorte counties, many burial mounds yielded human remains and funerary objects.

Efforts are underway in the 2020s to return Indigenous remains in museums and collections to their respective nations for reburial, as mandated by the Native American Graves Protection and Repatriation Act (NAGPRA). Indigenous nations from the Grand Kankakee Marsh and other Great Lakes regions suffered the psychological trauma of losing their ancestral lands and burial places. These graves were central to their cultural and spiritual beliefs, representing a sacred bond with their ancestors that was violently severed. This has contributed to their historical trauma.

In 2002, the U.S. Department of Agriculture (USDA) and its Natural Resources Conservation Service (NRCS) partnered with the Pokagon Band of Potawatomi Indians to restore of the former Kankakee Marsh in North Liberty. Since the 1990s, the Pokagon Band has been reclaiming historic lands. The restoration work exists within a larger framework where Indigenous traditional ecological knowledge is gaining recognition from the U.S. EPA and other organizations for its benefits in land and nature management.

Legacy of the marsh

The Grand Kankakee Marsh's history has unfolded through the media, from newspapers and books to a 2020 Lakeshore PBS documentary, "Everglades of the North: The Story of the Grand Kankakee Marsh". The loss of wetlands like the Grand Kankakee Marsh drives wetland conservation movements nationally and globally. While the historical drainage converted the region into highly productive farmland, environmental groups currently advocate for the restoration of approximately 10% of the original marshland by reconnecting the river's historic meanders. In 2001, the U.S. Army Corps of Engineers (USACE) recommended similar restoration strategies for restoring the Kankakee River, including reconnecting isolated meanders.

Recent legal challenges complicate conservation efforts by removing wetland protections to facilitate development. In 2021, the Indiana legislature removed protections for Class I wetlands. In 2023, the law was further amended to ensure it is enforced. The 2023 Supreme Court ruling in Sackett v. EPA has also created obstacles for U.S. wetland protection by focusing on private land-use rights. In 2024, the Indiana legislature passed a law to reduce Class III wetland protections. A 2025 report by the Natural Resources Defense Council (NRDC) argued the Sackett ruling threatens to remove protections for tens of millions of acres of existing wetlands, leaving them vulnerable to pollution and destruction.

Conservation projects have faced public scrutiny. In Hopkins Park and Pembroke Township, reports indicate that conservation efforts conflict with the land-retention efforts of Black farmers. This tension is situated within a broader history of Black land loss in the United States where institutional racism in government policies contributed to a 90% decline in Black farm ownership nationwide since 1900. Part of the township's culture and traditions include the annual Pembroke Rodeo, founded by Thyrl Latting in 1964, which celebrates the history of Black cowboys.

Significant flooding has persisted over a century due to channelization, land elevations, and blocked drainage. Following 2018 flooding, officials launched a 40-year sediment and flood control plan, employing rock-filled filter bags to prevent bank scouring and erosion, as well as planting native vegetation and installing riprap on banks. However, drainage district regulations often hinder private restoration by requiring strict ditch and tile management to prevent flooding on neighboring croplands.

As climate change increases annual precipitation, floods worsen in the Kankakee region and require mitigation. Changes in precipitation also increase chances of runoff and infiltration of groundwater resources with chemical loads. By 2080, high-emissions scenarios predict a 20% increase in the rate of the Kankakee's streamflow, increasing the chances of 100-year floods by 50%, and creating wetter winters and springs.
