Monitoring of Sediments and Nonpoint Source Pollution Removal at the Spring CreekWetland Project, Bowman-Haley Lake, North Dakota

摘要

Bowman-Haley Reservoir is a popular lake located along the western part of theNorth Dakota/South Dakota border. The lake was constructed in 1966 as a flood control and water supply reservoir. The lake initially had good water quality; however, as the lake aged, water quality declined. Suspended solids, excess nutrients and corresponding turbidity, excess algae growth, and low winter dissolved oxygen concentrations are the main concerns. Recreational use of the lake has also declined. The local Soil Conservation Service developed a plan to improve the water quality of the reservoir (Soil Conservation Service 1990) which primarily consists of reducing nonpoint source pollution through good agricultural land management. In addition, a 23-acre wetland was constructed in 1991 on Spring Creek with the dual purposes of water quality enhancement and creation of waterfowl nesting habitat.
