Cossayuna Lake — 665 acres straddling the Washington County line south of Lake George — is a warm-water fishery and summer cottage lake that sits just outside the Blue Line, technically in the broader Lake George watershed but operationally its own world. The lake has a state boat launch on the northeast shore (Cossayuna Lake Road, cartop and trailer access) and draws a local crowd for bass, panfish, and early-season pike, though no formal stocking or survey data is on file with DEC. It's quiet-ish for a developed lake — more rural Route 40 than Route 9N — and the water stays warm enough through Labor Day that it functions as a late-season swim alternative when the bigger Adirondack lakes have already turned cold. If you're camping at Glen Hudson or Huletts and want flatwater paddling without the tour-boat traffic, Cossayuna works.
