flows E to Otter Bight, 3 mi. N. of Fort Glenn on NE coast of Umnak I., Aleutian Islands. 4 miles long.
Name published by U.S. Geological Survey (USGS) (in Byers, 1959, pl. 41). This name may have been derived from the Aleutian word "idakuq," meaning "it leaves; it emanates from" (in Geoghegan, 1944, p. 109), and have been arbitrarily "clipped" for cartographic convenience.
