    Wild River Alaska

Nature & Science

The Alagnak Wild River, designated as a Wild River by Title VI, Section 601(25) and 603(44) of the Alaska National Interest Lands Conservation Act (ANILCA), preserves the upper 56 miles of the river in a free-flowing condition, and protects the river and its immediate environment for the benefit and enjoyment of present and future generations. The river is managed free of impoundments and diversion, inaccessible by road, its shorelines primitive and its water unpolluted. The Alagnak is the most popular fly-in fishery in southwest Alaska, and has experienced a significant increase in use over the last several years. The Alagnak Wild River protects populations of all five species of pacific salmon, as well as significant rainbow trout, arctic char, arctic grayling, and northern pike populations. The increasing sport fishery on the river is a topic of concern to many subsistence users and other local residents.

Wave action from increased motorboat use on the Alagnak Wild River threatens archaeological sites.

While current and wave erosion is a natural process, increased erosion from motorboat wakes has become one of the greatest threats to archaeological sites along the banks of the Alagnak Wild River. Boaters can reduce the destructive process by slowing their crafts in areas where erosion is evident.
