Successful Habitat Restoration Projects
Morgan Point Bendway Closure Structure, Arkansas
The $2.7 million project was designed to restore flows to the Morgan Point Bendway, which was cut off when the Wilbur D. Mills Dam was constructed. An overflow weir closure structure at the mouth of the bendway and a water supply pipeline from the dam was built. Additionally, some areas of the shoreline were planted with cypress, and fish shelters were placed in the bendway. Approximately seven miles of river habitat were restored, resulting in 966 surface acres of aquatic habitat, of which 202 acres will be emergent wetlands.
Deroin Bend Floodplain Restoration, Missouri
The $3.6 million project consists of notching the bank revetment and excavating a pilot channel to connect a remnant channel and a scour lake created during high water events to the main Missouri River channel. The three and one half mile channel will restore about 70 acres of slower water and benefit 40 acres of backwater and wetlands. Approximately 800 acres of cropland would be restored to flood plain forest, riparian habitat and sand dunes. The restored floodplain will have increased value for waterfowl, wading birds, and river fish.
Murphy Island, Santee Wildlife Refuge, South Carolina
The $410,000 project included construction of 5,400 feet of setback dikes adjacent to the Atlantic Intracoastal Waterway and increased the height of 4,500 feet of existing dikes. Seven water control structures were also installed, permitting water level management designed to increase the production of marsh plants and attract more than 50,000 migrating waterfowl.
Center Hill, Caney Fork Instream Structures, Tennessee
The $489,000 project consists of placing boulders in 16 sites, substrate features in eight locations, four riparian zone revegetation, or replanting, sites and one combined riprap/revegetation site in a 26 mile reach of the Caney Fork downstream of Center Hill dam. The boulders and substrate features will be placed by helicopter. This will restore diversity to the instream habitat providing high flow refuge for fish, substrate components for the aquatic invertebrate population, and improved spawning areas. The riparian zone restoration will create 12,200 square meters of prime wildlife habitat.
Thornton Creek Habitat Restoration, Washington
The $465,000 project consists of restoring native riparian vegetation, creation of a fish rearing pond and other work adjacent to the mouth of Thornton Creek where it enters Lake Washington. The restoration is expected to provide improved conditions for coho and cutthroat smolt production and improved conditions for small mammals and waterfowl and other migratory birds.
