New Sign Campaign To Raise Awareness

In conjunction with the Michiana Stormwater Partnership (MSP), the City of Mishawaka will be placing signs near all major surface water bodies in the City. The signs are intended to alert residents to the abundant surface water bodies in the area, and to serve as a reminder to keep these vulnerable resources clean and free of pollutants.

For more information, see the MSP Press Release.

Water quality and the St. Joseph River

The St. Joseph River is a major waterway, its course winding for more than 200 miles in northern Indiana and southern Michigan before emptying into Lake Michigan . Polluted runoff from urbanized areas, agriculture, forestry, and construction causes physical changes to the river’s channel, harms fish and wildlife populations, kills native vegetation, fouls drinking water supplies, and can impair recreational uses.

Municipal Separate Storm Sewer System (MS4)

Storm sewers collect surface runoff and convey these flows directly to the river without treatment. Pollutants picked up as runoff enter the storm sewer system causing serious water quality problems. The MS4 program is designed to minimize the discharge of pollutants to the storm sewer system.

Protection under the Clean Water Act

The Clean Water Act, administered by the Environmental Protection Agency (EPA), was implemented to protect our nation’s water supply. As part of this effort to protect and maintain water quality, the EPA established the Municipal Separate Storm Sewer System Program, known as MS4. Both the City of Mishawaka and Bethel College have been designated MS4 entities and must comply with the MS4 program requirements. Mishawaka and Bethel have partnered as co-permittees under the MS4 program, sharing responsibilities for program implementation.
