This is a list of dams in New York that have been removed as physical impediments to free-flowing rivers or streams.
The tall Cuddebackville Dam on the Neversink River, a tributary of the Delaware River, was built in two portions dating from the 1820s (for water diversion into a canal) and 1915 (for hydroelectric power). The dam had been abandoned since 1945, and was removed in October 2004 by the U.S. Army Corps of Engineers in a novel partnership with the Nature Conservancy. The removal benefited aquatic life in the area, specifically the Dwarf Wedge Mussel and the American Shad. The dam was said to be the first in New York to be removed solely for environmental reasons.
In 2023 two dams were removed from the lower Saranac River in Plattsburgh: Indian Rapids Dam and Fredenburgh Falls Dam. Funding to support the project flowed from multiple streams: $536,000 from Patriot Hydro, $175,000 from the U.S Fish and Wildlife Service, $65,000 from New York State Electric and Gas, and $370,000 from the Lake Champlain Basin Program (made possibly by the Infrastructure Investment and Jobs Act, signed into law by President Biden in 2021).
