The King Salmon River is a 45miles tributary of the Nushagak River in southwest Alaska, United States.[2] It flows eastward from headwaters 60.285°N -158.4758°W at a small unnamed lake in the Taylor Mountains to its confluence with the larger river about 220miles north of Nushagak Bay.
There are many rivers in Alaska bearing the name King Salmon River, including tributaries to the Egegik River and Ugashik River systems in southwest Alaska alone. The name is also occasionally confused with that given the Kenai River, a popular fishing stream located in the Cook Inlet drainage of southcentral Alaska.
Besides king salmon, the river is also hosts pink salmon, grayling, burbot, whitefish and Arctic char.
