Blue Lake (Tlingit: Gajook Héen Yik.áayi[3]) is a 3 miles (4.8 km) long reservoir located 6 miles (9.7 km) east of the town of Sitka, on the west side of Baranof Island, in the Alexander Archipelago of Southeast Alaska.

[1] The local descriptive name was reported in 1910 by Knopf (1912, fig 4), in United States Geological Survey.

There are also many avalanche chutes located along the road which can pose a hazard or block it completely in winter.

Alaska permits allow Sitka to export approximately 9.5 billion gallons of raw water annually.

[9] This agreement has allowed Eckert Fine Beverages to export a few thousand gallons of Blue Lake water to a California subsidiary, Reigncane Vodka.
