The Koyuk River is a river on the Seward Peninsula of western Alaska, US. The river originates in the interior of the peninsula, at the Lost Jim Lava Flow of the Bering Land Bridge National Preserve, where it flows southeast towards the mouth of Norton Bay on Norton Sound. The native village of Koyuk is located at its mouth. The two major tributaries are the Peace and Salmon Rivers.
Etymology
Its Inuit name was reported by Captain Tebenkov (1852, map 2), IRN, as Kvyguk or Kvieguk. The Western Union Telegraph Expedition spelled the name Koikpak ("big river"). The Seward map of 1867 gives Koipak, and later as Kayuk, Koyuk, and Kuyuk. The Kanguksuk is also known as the Left Fork of the Kviguk (Koyuk). The present spelling comes from A. H. Brooks, USGS, in 1900.
Geography
Its lower course is a broad estuary affected for many miles by the tide and having little current. The river valley is a region of rather low relief, the adjacent hills being nowhere comparable to those of the Tubutulik River or the head of Fish River. The flat mud- and sand-filled basins are relatively restricted in area. There are several rapids. For a few hundred feet, the gradient of the river bed is very high and the channel filled with big blocks. The river banks are rocky and made up of horizontally bedded lava flows, from which the boulders that filled the channel are broken. The mouths of two or three large tributaries come in from the south and several smaller ones from the north.
Aqua fauna
The river is well known for its fishing resources. the fish species reported are Chinook Salmon (Oncorhynchus tshawytscha), Sockeye Salmon (Oncorhynchus nerka), Coho Salmon (Oncorhynchus kisutch), Steelhead Trout (Oncorhynchus mykiss), Dolly Varden (Salvelinus malma Walbaum), Rainbow Trout, Northern Pike, Grayling, Dolly Varden, and Arctic Char.
Fauna
The faunal species reported in the river basin are moose, grizzly bear, black bear, caribou, wolves and waterfowl.
Water sports
The river is also a popular water sports Kayaking and Rafting.
