Ipnavik River

The Ipnavik River is a 68-mile-long (109 km) tributary of the Colville River in the Alaska North Slope which was part of the traditional lands of the Iñupiat, who named it "Ipnavak" which means "place where young Dall sheep grow up" with its headwaters in the Brooks Range. The Ipnavik River flows northeast to meet the Colville River 50 miles (80 km). It flows north northeast of Howard Pass, which is the mouth of the Ipnavik. The name was documented by the United States Geological Survey in 1925.

The "Ipnavik River flows northeast to the Colville River, 50 miles (80 km) north northeast of Howard Pass, in the North Slope".[1][4] "The Ipnavik River (Fig. 29) heads in the Brooks Range and flows northeast 109 kilometres (68 mi) to the Colville River at lat. 68'54'~, long. 156O27'W. It has a drainage area of 1,525 square kilometres (589 sq mi) and an estimated average annual flow of 6.9 m3/sec (245 cfs). The upper Ipnavik is swift and confined to a single channel. The lower river is braided an3 has short, narrow bars. Aquatic vegetation is sparse. The Ipnavik flows clear throughout most of the summer.

History

The Iñupiat are the indigenous people of the Ipnavik River area. Their ancient hunting structures including arrowhead fragments and "piles of caribou bones" can still be found on the land, for example "on a ridge between Surprise Creek and Kokolik River."[3]

In 2012 Congress was considering designating either all or part of the Ipnavik River for inclusion in the National Wild and Scenic Rivers System along with the a section of the Colville River, and the Awuna River, Etivluk River, Nigu River, Kuna River, Kiligwa River, Nuka River, and Utukok rivers as well as Driftwood and Carbon creeks.[5]: 24

The fish with the widest distribution in the Ipnavik River is the Arctic grayling Thymallus arcticus, or Sulukpaugaq in the Iñupiat language. It is a "key subsistence species"[6]: 43  for the Iñupiat people of the Alaska North Slope, and it is "one of the most important species" for Sport fishing in Alaska.[6]: 47
