The Walnut Creek Watershed is located in western Polk and eastern Dallas counties in central Iowa. The 53,000 acre landscape is rapidly changing, with over six-square miles being developing between 2001-2011. The creek itself is a primary source for the metro area drinking water, joining up with the Raccoon River just above Des Moines Water Works.
A Watershed Management Authority (WMA) was developed to address environmental concerns seen throughout the watershed and in the creek. A watershed management plan was developed by the WMA to showcase ways the urban and rural communities can overcome these concerns and increase the overall quality of the watershed. Please visit the Watershed Management Authority page under the About tab to view the watershed management plan.
