Alagnak Wild River

Alagnak Wild River is the upper 69 miles of the Alagnak River on the Alaska Peninsula, flowing from Kukaklek Lake beside Katmai National Park and Preserve. It was added to the National Wild and Scenic Rivers System in 1980.[1]

Description

The designated reach runs 69 miles from Kukaklek Lake and lies adjacent to Katmai National Park and Preserve on the Alaska Peninsula.[1]

Fish and wildlife

The river provides critical habitat for many Pacific salmon species, and residents still use salmon for subsistence. It also supports brown bears, caribou, moose, beavers, foxes and birds.[1]

Recreation

Visitors come for sport fishing, including fly-in fishing, and for rafting, with lazy floats on the braided river and Class III rapids in some sections. Primitive camping and sport hunting and trapping also occur. Much of the river corridor is private land, so visitors need landowner permission before entering. A baseline water quality and inventory study was completed in 2001 and research continues.[1]

The river

The Alagnak River is 64 miles long and a tributary of the Kvichak River, with a catchment of about 1,400 square miles. It begins as the outflow of Kukaklek Lake and reaches Bristol Bay via the Kvichak. The upper valley is mostly spruce, miles 7 to 14 pass through a narrow canyon, and the Nonvianuk River joins near mile 20 [2].

Designation and Katmai

The river was designated a National Wild and Scenic River on December 2, 1980, when ANILCA also established the Alagnak Wild River. It starts in Katmai National Park and Preserve; because the park legislation did not allow hunting or fishing, the Alagnak Wild River was created to allow limited sport and subsistence hunting, trapping, and fishing [2].

Name

The National Park Service says the name means making mistakes, since the river often splits into branches, earning it the nickname Branch River. Other sources link it to a Yupik word for a red berry or wild raspberry [2].

Salmon and wildlife

Sockeye, pink, chum, king, and silver salmon are found in the river, and large runs support a significant bear population. It is one of Alaska most important sport fishing rivers. Other wildlife includes grizzly and black bears, moose, caribou in winter, and rainbow trout, char, Arctic grayling, and northern pike [2].

Boating

The ravine has Class 1 to 3 rapids, which are dangerous for inexperienced rafters, especially at high water, and the river is navigable for canoeists [2].

History

People may have arrived about 14,000 years ago, with documented settlement about 9,000 years ago. Russian captain Tebenkov was the first European to document the river, in 1852. The North Alaska Salmon Company built canneries in 1900, which Libby, McNeill and Libby bought in 1916, and the cannery closed in 1936 and burned in 1937. Hunting and fishing lodges were established around 1957 [2].
