City of Owatonna Stormwater Management

"Clean H2Owatonna" is the City of Owatonna's Stormwater Management Program to keep our streams, river, and waterways  clean of pollution.

Stormwater is water from rain or melting snow that does not soak into the ground. Instead, it flows from rooftops, across paved areas, and through sloped lawns. As stormwater moves across these surfaces, it can pick up and carry along pollutants such as yard and pet waste, sediment, chemicals, oil, grease, and other possible contaminants. This water enters our community storm drains and flows directly, untreated, to Maple Creek, Crane Creek, or the Straight River.
