Recreational use of the controlled lakes falls under DEP regulations. Fishing and self-powered boating are allowed with a valid DEP permit and New York State Department of Environmental Conservation-issued fishing license. Swimming is prohibited.

Ice fishing is allowed on Lake Gilead during the winter. Fish species present include (but are not limited to) largemouth bass, rainbow, lake and brown trout, chain pickerel, yellow perch, and panfish. In the 1990s a local fisherman illegally introduced northern pike, though they are rarely caught.
