flows SE to Cascade Creek, 20 mi. NE of Goodnews, Kilbuck-Kuskokwim Mts.
Eskimo name reported as "Wahmus" or folk etymologized into "Watermouse Creek" according to G. C. Martin (1919, p. 40), U.S. Geological Survey (USGS). In 1919 G. L. Harrington, U.S. Geological Survey (USGS), reported that the name is a corruption of "Bartimeus," the baptismal name of an Eskimo for whom the stream was named. He also reported that the Eskimos called it "Nakahkpuk," said to mean "stream between mountains." Gold was found on this creek in 1917 by an Eskimo herding reindeer in the vicinity. This discovery resulted in the Discovery group of peoductive placer mines located along the creek (Brooks, 1921, p. 225).
