Collaborating to Improve Water Quality and Habitat in Our Urban Watershed
What We Do
The MWMO protects water quality, habitat and natural resources in and around the Mississippi 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.
