Summary: The proposed project includes fully drawing down the lake to approximate water surface elevation of 1101 mean sea level and maintaining that level over the fall and winter months to desiccate and freeze zebra mussels. While the lake is in the drawn-down condition, the entire park would be closed to all citizens to reduce safety risks involved with ice formation and exposed sediments/mud. Draw down is proposed to begin in October 2018 and be completed on or before December 1, 2018.
In addition, the chemical Rotenone would be applied to any remaining pools of water contained within the lake to kill the common carp. Rotenone would be applied during either the fall or spring months depending upon when full draw down levels could be achieved. Following the Rotenone application, the lake would be allowed to naturally refill which would take only one season under normal precipitation events.
After the lake refills, the Nebraska Game and Parks Commission would restock the lake with a variety of desired sport fish to include hatchery-sized, one-year old and adult-sized fish.
