Water Quality Improvement Plans

Iowa's streams, lakes and rivers need improvement. But where do we start?

Water quality improvement plans investigate streams and lakes on Iowa's impaired waters list. The ultimate goal is to improve water quality and remove streams and lakes from the impaired list. The plans, developed by the DNR, use research results and the public's input to help reduce the amount of pollutants reaching our water. 

Water quality improvement plans identify and locate water quality problems in a stream or lake, and suggest ways that communities can improve their stream or lake to meet Iowa's water quality standards.
