Blue Lake

Blue Lake (Tlingit: Gajook Héen Yik.áayi) is a long reservoir located east of the town of Sitka, on the west side of Baranof Island, in the Alexander Archipelago of Southeast Alaska. Name and geology The local descriptive name was reported in 1910 by Knopf (1912, fig 4), in United States Geological Survey. Blue Lake, as its name suggests, possesses a deep blue hue to its water. Blue Lake's water sources are partially from snowpack and small glaciers from the glacially carved, U-shaped, Blue Lake valley in which it lies. Dam Blue lake was first dammed in 1913 by Sitka Wharf and Power Company. It sold its operation to the city in 1942. Floods damaged the infrastructure in 1943 and 1947.
