Green Bay Field Office Private Lands Biologists Gary Van Vreede and John Riens recently completed the repair of a failing wetland impoundment structure located on a private property in Brown County, Wisconsin. Originally constructed in the 1950’s by the Natural Resources Conservation Service to control agricultural runoff, the impoundment’s water control structure had deteriorated and no longer functioned properly. Concrete was used to repair the damaged water control structure and new fill material was placed around the inlet to reconstruct portions of the impoundment that had washed away. A number large trees and shrubs which had grown up around the structure were also removed to prevent further damage from expanding roots. To prevent destruction from burrowing muskrats, chain link fencing was laid along the underwater portion of the impoundment structure. The two acres of wetland created by this structure will provide valuable habitat for variety of migratory and resident wildlife species. The wetland will also serve to slow the velocity of water from the 300 acres of agricultural lands that flow into the basin, thus filtering out sediments and improving downstream water quality.
