Sellakhskaya Bay – shallow (up to 14 m) bay in the southeastern part of the Laptev Sea, between the Manyko Peninsula in the west and Turuktakh Cape in the north, the Sakha Republic (Yakutia), Russia. Its length is around 60 km, width up to 25 km, and depth at the entrance over 10 m. The area is 1,800 km2. The coasts are low and befringed by shallows. The coast is largely a heavy-going swampy area. By wind surge they are covered with water, getting dry by offshore wind. Numerous rivers (the Sellakh, the Danilkina, the Maksunuokha), creeks, and brooks flow into S. B.
