The Project facility is located at lower Winooski Falls on the Winooski River ten miles upstream of its confluence with Lake Champlain, between the city of Winooski, on the north bank, and the city of Burlington, on the south bank. This run-of-river facility has a refurbished spillway with crest gates abutting a historic timber crib dam that dates from 1876. The dam is on the National Register of Historic Places as part of the Winooski Falls Mill District. There are two plant species listed by the state as threatened and endangered in the vicinity of the project that were the subject of mitigation and protection activities at the time of the facility’s construction. The applicant also constructed fish passage facilities and a riverside park and trail as part of the project.
