This feature layer is a spatial representation of most of the DAM facilities in the StreamNet database. Information about the location of each dam was collected from StreamNet personnel at WDFW (Washington Dept of Fish & Wildlife), ODFW (Oregon Dept of Fish & Wildlife), IDFG (Idaho Dept of Fish & Game), and MFWP (Montana Fish, Wildlife & Parks) and the tabular information about each dam in the StreamNet database was then added to each dam point in the GIS layer. California data comes from the StreamNet's partner project "CalFISH" (http://www.calfish.org) which contributes data compatible with the StreamNet database.
