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 Willow Creek, Maple Creek, Crane Creek, or the Straight River and eventually the Cannon River.


 Provide us feedback!

The City of Owatonna appreciates any feedback, comments, or question regarding the MS4 Program, SWPPP, and Stormwater Management Plan/Ordinance. A copy of the MS4 Permit, Program, and SWPPP document are available on the 2nd floor of the City Administration Building for viiewing during normal office hours and on the Stormwater Website. The documents will also be made available during the Steele County Fair at the CRWP/City Booth in the Izaak Walton League Building.

You may also submit a Comments Sheet to or write your comments through the Stormwater Hotline.


The City is seeking organizations and individuals to make a positive impact on the community and our natural resources through various stormwater programs.
