Lower Hatchie National Wildlife Refuge

Happy Hollow Ditch Project

There are two water control structures and one culvert pipe in the waterfowl that needs to be replaced. These structures have become warped and difficult to insert and remove stop logs and they are leaking; therefore, replacement is needed immediately to meet our waterfowl objectives and general water management. The pipes and structures will need to be delivered by the vendor at 234 Fort Prudhomme Drive Henning, TN 38041. Refuge staff will be installing the structures.
