LINCOLN – A renovation of the existing fish population in Lake Yankton, located below Gavins Point Dam, is set to occur on Sept. 10. The project includes drawing Lake Yankton’s water level down four feet and applying the chemical rotenone to eliminate the fish population.
Record Missouri River flooding in 2011 allowed undesirable fish species to enter the lake. These fish species are now dominating the fishery and have destroyed the aquatic vegetation and water quality in this popular fishing lake. Lake draw-down will begin the middle of August with the lake scheduled to start refilling immediately after the renovation. Fish species to be restocked into the lake following the renovation include bluegill, largemouth bass, black crappie, channel catfish and walleye.
The fish renovation is a joint effort among the Nebraska Game and Parks Commission; South Dakota Game, Fish and Parks; and the U.S. Army Corps of Engineers. For more information, contact Jeff Schuckman at the Norfolk Game and Parks Office at 402-370-3374.
