Clackamas River watershed atlas

Metro received grant funding from the U.S. Environmental Protection Agency in 1995 to gather digital, or computerized, geographic data for the Clackamas River watershed. This atlas was produced as one way to share the information collected with resource managers, policy makers, and people living in and interested in the Clackamas River watershed. The project study area is the entire land area draining into the Clackamas River in northwestern Oregon, referred to as the Clackamas River watershed. The watershed is part of the lower portion of the Willamette River basin
