The McArthur River is a 55 km long river in southwest Alaska . The river was named in 1910 by the US Coast and Geodetic Survey (USC & GS) after the steamship McArthur .

River course

The McArthur River is fed by a nameless glacier in the Neacola Mountains at an altitude of 550  m . It flows 1.5 km to the south before the glacier tongue of McArthur Glacier is fed. The McArthur River now flows 7 km to the east and then turns to the southeast. It is flanked by the mountains of the Neacola Mountains. The river leaves the mountains. The glacier tongue of the Blockade Glacier reaches up to a few meters to the McArthur River and feeds it with melt water. After 10 km the Noaukta Slough , an arm of the Chakachatna River , flows into the McArthur River on the left. This flows a further 20 km in a predominantly south-easterly direction through the coastal plain and finally flows 10 km north of Tyonek into Trading Bay , a stretch of coast in the west of the Cook Inlet . The actual Chakachatna River meets the McArthur River only 5 km above the mouth.

The Kustatan River used to form a right arm of the McArthur River, which flowed directly into the sea. However, the upper area of ​​the river arm was largely cut off, so that the Kustatan River today essentially receives its water from the glacier-fed tributary Blacksand Creek .

Fish fauna

The McArthur River and the Kustatan River are visited by silver salmon for spawning . A smaller population of king salmon spawns in the McArthur River and its tributary, the Chakachatna River.
