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.

A TMDL is a calculation that determines how much of a pollutant can enter a specific stream or lake in one day and still allow the lake or stream to meet the state's water quality standards. This calculation is just one part of the larger water quality improvement plan.
The Federal Clean Water Act created the TMDL process, which requires developing a TMDL for pollutants that cause a stream or lake to be placed on Iowa's impaired waters list. In Iowa, the process goes far beyond a calculation and becomes a plan for improving water quality that relies on the support and participation of Iowans in the watershed.
