Oregon Drinking Water Protection Program Interactive Map Viewer

This map viewer was produced by Oregon Dept. of Environmental Quality in partnership with the Oregon Health Authority to help identify and protect sources of drinking water (streams, rivers, lakes, reservoirs and groundwater aquifers) for use by public water systems and their communities. Land uses and potential sources of pollutants identified on regulatory databases within public drinking water source areas (DWSAs) can be viewed, as well as Oregon's ground water protection areas.
