This coverage contains 6th order HUCs for the United States portion of the Columbia River Basin. The original version of this coverage was obtained from Streamnet in 1999. This version is the result of three major revisions by the Northwest Habitat Institute in cooperation with the Northwest Power Planning Council and the Bonneville Power Administration. In addition to 6th order HUCs, this coverage also has attributes for 4th and 5th order HUCS, watersheds, subbasins, and ecological provinces.
