Redoubt Lake, or Kunaa Shak Áayi, is a long, narrow lake on Baranof Island near Sitka in southeast Alaska, occupying a deep glacial basin within Tongass National Forest. One of the largest meromictic lakes in North America, it has an upper layer of fresh water over trapped salt water, likely because a former fjord was cut off from the sea. Named Ozero Glubokoye by Russian navigator Ivan Vasilyev in 1809, it became economically important in Russian America through a nearby settlement and a major sockeye salmon fishery that supplied Sitka. Its significance endures in both its unusual waters and its salmon-harvest history.
