Water retention top issue of Minnesota River Congress meeting

MANKATO – As climate change has brought more big rain events and as millions of acres of farmland in the basin have had upgraded tile drainage systems installed, too much water has flowed too quickly to ravines, streams and eventually larger rivers like the Minnesota. That’s caused extensive erosion of ravine, stream and river banks that sends sediment laced with nutrients and pollutants into the rivers.
That sediment and nutrients deteriorate water quality and, as it flows down the Mississippi, worsens the Dead Zone in the Gulf of Mexico.
The Minnesota River Congress will meet June 15 at the Kato Ballroom for its 14th full session. | READ MORE
