| Abstract |
Lake Cochrane is one of the few deep high quality prairie lakes in northeastern South Dakota. Local interests tried unsuccessfully for several years to develop measures to reduce sediment inflow. The proposal to develop sediment traps as a part of the lake's perimeter road system was selected for a grant award under EPA's 'Clean Lakes' program initiated in 1975. This small lake preservation project utilized the technical and/or financial resources of every level of government. For an allocated cost of about $20,000, three sediment traps were developed to control the sediment inflow from 66% of the lake's watershed area. By incorporating the sediment traps into the perimeter road system, 2700 feet of new gravel road, the sediment traps, and a new boat access area were constructed at a cost of $34,700. In addition, two of the sediment traps have been utilized as fish rearing ponds. Due to limited data and numerous sediment-nutrient producing activities occurring concurrently, it has been difficult to evaluate the impact of the project on the lake. Preliminary evidence indicates good suspended solids removal in the sediment traps. There is evidence, however, that temporary storage of runoff water may not provide any nutrient removal. |
