ROCK-KOSHKONONG LAKE DISTRICT: RES-Lake Koshkonong/Mud Lake Wetland Restoration

The Rock Koshkonong Lake District will use dredge spoils from a nearby location on the lake to re-create an eroded barrier of land that protects the Mud Lake wetland from the main lake\2019s wave action, arm the barrier with riprap, and re-create a wetland behind the barrier. This restored wetland is the subject of the grant, as well as the Mud Lake wetland complex which is being protected. Another facet of protecting the Mud Lake wetland from carp congregating there, the District will also build a navigation-friendly carp barrier between the lake and the wetland. In the spring, without such a barrier, carp migrate in great numbers into Mud Lake, creating disturbance to aquatic plants and displacing other fish spawning.
