flowing N to Bering Sea, 3.2 mi. W of Cape Idak on NE tip of Umnak I., Aleutian Islands.
Name published by U.S. Geological Survey (USGS) (in Byers, 1959, pl. 41). This name may have been derived from the Aleutian word "kadigukuq," meaning "it stands against; it is in front of" (in Geoghegan, 1944, p. 112), and have been shortened for cartographic convenience.
