Abstract: Bowman-Haley Reservoir is a flood control and water supply reservoir located in the southwest corner of North Dakota. The popular reservoir has suffered from a variety of water quality problems including excess suspended sediments and nutrients. As part of an overall watershed management program, a 24-acre wetland was constructed along Spring Creek, a major tributary into the reservoir. The wetland was intended to remove nonpoint source pollutants from Spring Creek storm flows. Constructed on U.S. Army Corps of Engineers lands by Ducks Unlimited, the wetland was also to serve as waterfowl nesting and resting habitat. During its first 2 years in operation, the wetland was monitored for its ability to remove sediments, nutrients and herbicides from inflows originating from Spring Creek. Results of the monitoring indicated that the wetland was able to effectively remove suspended sediments and, to a lesser degree, total phosphorus. The wetland was ineffective in the removal of nitrogen. Because of the concentrations of herbicides encountered, no estimates on treatment effectiveness could be made. The ability of the wetland to treat nonpoint source pollutants was hampered by the newness of the wetland and by the construction and operation of the wetland to facilitate waterfowl use.
