Collaborating to Improve Water Quality and Habitat in Our Urban Watershed

The MWMO watershed encompasses 25,309 acres (39.5 square miles) of fully developed urban lands and waters. We partner with our member communities to invest in green infrastructure that captures, cleans and reuses stormwater runoff.
