The Nushagak headwaters are a primary spawning area for King, Sockeye, Coho, and Chum Salmon and therefore are extremely rich fisheries for Arctic Grayling, Rainbow Trout, and Dolly Varden. The upper river is mid sized and spruce forested draining venerable, dome shaped, weathered mountain ranges. It lends itself to sight fishing to Char among salmon and to fishing streamers and flesh flies deep among woody debris for Rainbow.
