Abstract

Brushy Creek is a tributary of the Raccoon River, which is a regular source of drinking water for over 400,000 Iowans. Regular monitoring by Des Moines Water Works (DMWW) and Agriculture’s Clean Water Alliance (ACWA) over the last eight years has shown the stream to be highly impaired for coliform bacteria and nitrate. Both Brushy Creek and the Raccoon River are on the 303(d) impaired waterbody list. A December 2005 fish kill in Brushy Creek resulted in administrative actions against seven livestock producers. Several open feed lots exist in the watershed. The community of Roselle (in the Brushy Creek watershed) has been identified by IDNR as unsewered, and many dwellings throughout the watershed discharge untreated human waste. No Watershed Improvement Association (WIA) exists in this sparsely-populated area. This outcome-based project will: • Enhance nutrient and manure management to reduce agricultural inputs to the stream. • Assess the amount of human waste reaching the stream from Roselle. • Engage and inform local residents so a WIA can be formed. • Monitor performance through a rigorous water and soil testing program. This project embraces a concept of participation from all levels of government, commodity organizations, and the private sector. The largest drinking water utility in the state will lead and administer this effort. The participating parties will work to establish a functioning WIA so that progress achieved through this project will be robust and long-lasting. The participants believe this will be the most effective approach to correct the situation, and will serve as a model for other problem watersheds throughout the state.
