Minidoka National Wildlife Refuge Wetland Restoration (ID)

Overview of a wetland feature and its respective historic water control structures on Minidoka NWR. 

Ducks Unlimited, Inc. is working with the U.S. Fish and Wildlife Service to replace two water control structures on the only managed wetlands within the Lake Walcott segment of the Minidoka National Wildlife Refuge in Idaho. Lake Walcott, located along the Snake River in Cassia County, is downstream of American Falls Reservoir, which is generally regarded as the state’s most critical shorebird habitat. 

Lake Walcott is managed by the Bureau of Reclamation primarily for irrigation water storage. The old structures were failing and allowed carp to migrate into the wetlands during the spring and summer, where they destroyed valuable wetland vegetation.  As part of the Middle Snake River Conservation North American Wetlands Conservation Act (NAWCA) grant project, the new structures will be fitted with fish screens to prevent carp from entering the wetlands.Replacement of the two structures will also restore approximately 142 acres of emergent wetlands and mudflat habitat. The structures will greatly improve management of water elevations in the wetlands. 

This project will further enhance the region’s wetland, waterfowl, and shorebird habitat.
