New Structure in place.

A cooperative effort between Iroquois National Wildlife Refuge and Ducks Unlimited (DU) has helped to ensure continued quality habitat in the refuge's center marsh impoundment for years to come.  The 84 acre impoundment, originally constructed in 1969, consists of forested wetland, shrub wetland, emergent marsh and open water.  These diverse habitats provide nesting and migration habitat to a variety of migratory waterfowl, waterbird, shorebird and songbird species.

The original water control structure had deteriorated and was leaking, prompting refuge staff to make plans for its replacement.  The original galvanized half-round open riser was replaced with a plastic in-line structure.  The new structure will last longer, is safer and more secure and is less likely to be plugged by beavers.  The new structure was set 18 inches lower than the original structure, allowing the water in center marsh to be drained more completely when a total drawdown is desired.

The refuge has a long history of partnering with DU to complete habitat projects, so when additional funding was needed for the project we knew where to turn.  As usual, our call for help was quickly answered.  DU provided the water control structure and the refuge bought the pipe, rented the excavator and installed the structure.  This is another great example of the value of partnerships which allow refuge funds to be stretched to meet habitat goals and benefit the U.S. Fish and Wildlife Service's trust resources.
