Green Lake (Tlingit: Gageit' Tá)[2] is a lake/reservoir south of Sitka, Alaska. It is fed by the Vodopad River and outflows into Silver Bay.

The Medvejie Fish Hatchery short-term rears smolt (juvenile salmon) in net pens in Green Lake.[3]

The lake is artificially expanded by the Green Lake Dam. The rock-fill embankment dam is 1,130 feet (340 m) long.[4] Annually Green Lake Dam generates about 60 gigawatt hours of electricity.[4] Green Lake Dam works in tandem with the Blue Lake Dam to provide hydropower to Sitka.[5]

Green Lake height before damming was 230 feet (70 m).^[citation needed]
