Nowitna River
Alaska
The Nowitna River originates just south of Sunshine Mountain in the western foothills of the Kuskokwim Mountains and travels approximately 60 river miles to where it enters the Nowitna National Wildlife Refuge and becomes the designated portion of the Nowitna River. The designated reach of the river meanders northward, crossing the entire Nowitna National Wildlife Refuge before emptying into the Yukon River. Ecologically speaking, the Nowitna River is the heart and lifeblood of the Nowitna National Wildlife Refuge. Stream characteristics along the upper, middle, and lower portions of the Nowitna River differ notably, yielding wildlife and habitat diversity, providing scenic variability, enriching various recreational opportunities, and consistently delivering vital subsistence resources to people since prehistoric times. The meandering nature of the river has created highly productive terrestrial and aquatic habitats for fish, waterfowl, furbearers, moose, and other wildlife. Unique limestone bedrock deposits in the river’s headwaters produce nutrient- and carbonate-rich waters that reduce acidity and increase productivity in floodplain wetlands and waterbodies. Along its course, the Nowitna River is dynamic and variable, but remains consistently wild and productive.

Outstandingly Remarkable Values
Ecology
Fueled by mineral-rich floodwaters, the Nowitna’s constant reshaping of the land creates one of the most productive and biologically diverse river ecosystems in the Interior Alaska
Fish
A variety of habitats along the Nowitna River sustains a rich and diverse fishery making it an essential ecological lifeline for migratory and resident fish in Interior Alaska.
Culture
Human interactions with the Nowitna River and its resources have remained remarkably constant for countless generations with hunting, fishing, trapping, and gathering providing essential human needs since the earliest human arrivals in the region.
Scenery
The ever-changing Nowitna River offers a dramatic and varied visual tapestry from its swift headwaters in the mountains to the broad, meandering lowland floodplain, creating a vivid reflection of Interior Alaska itself—beautiful, diverse, and unforgettable.
