A "watershed" is an area draining into a river, lake, or other waterbody. Ecology and other state natural resources agencies have divided the state into 62 "Water Resource Inventory Areas" or "WRIAs" to delineate the state's major watersheds. Federal agencies frequently use an alternative watershed system based on USGS Cataloging Units or "HUCs" (Hydrological Unit Code). The federal system is similar to the WRIA system except that the basin groupings differ and the units extend beyond the Washington state boundary into Canada, Oregon, and Idaho.
