Etymology

The stream was published as Sucker River by the U.S. Coast and Geodetic Survey (USC&GS) in 1890. The current name was mentioned by R. G. McConnell of the Geological Survey of Canada in 1888. It was so named because of the "boulder stream rapids that extend three quarters of a mile up stream from its mouth."
