The Hendrie River is a small stream in Mackinac County on MichiganâÂÂs Upper Peninsula. It flows through mixed forest, wetlands, and glacial lakeplain within the Lake Michigan drainage of the south-central county.
Headwaters arise in small springs and peatlands in Mackinac County. The river follows a gentle gradient across low-relief terrain and alderâÂÂcedar swales before joining downstream waters of the Lake Michigan basin.
Upland forests include northern hardwoods (maple, birch, aspen) and conifers (white pine, hemlock, spruceâÂÂfir). Riparian corridors are characterized by alder thickets, cedar swamps, and sedge meadows. Cold- to cool-water fishes occupy spring-influenced reaches; warmer backwaters near the confluence support species typical of Lake Michigan tributaries in Mackinac County.
