Engineers Corps July 25, 2005 – Federal Register Recent Federal Regulation Documents

The U.S. Army Corps of Engineers, New Orleans District (CEMVN) is initiating a Supplemental Environmental Impact Statement (SEIS) for the Henderson Lake Management Unit feature, including the freshwater distribution structure element, of the Henderson Lake Area Atchafalaya Basin, Louisiana project, pursuant to the authority of the Flood Control Act of May 15, 1928 (Pub. L. 391, 70th Congress); and for the Recreational Development feature of the Atchafalaya Basin Floodway System, Louisiana project (hereinafter ``ABFS'' project), pursuant to the authority of the Flood Control Act of May 15, 1928 (Pub. L. 391, 70th Congress), as amended by the Supplemental Appropriations Act of 1985, Pub. L. 99-88 and as reauthorized and further amended by Section 601(a) of the Water Resources Development Act of 1986 (WRDA 1986), Pub. L. 99-662. The CEMVN is initiating this study to implement construction and operation of the Henderson Lake Management Unit, St. Martin and St. Landry Parishes, which is one of two authorized pilot management units for the Management Unit feature of the ABFS Project; the freshwater distribution structure element, of the Henderson Lake Area Atchafalaya Basin, Louisiana project in St. Martin and St. Landry Parishes, Louisiana; and the Recreational Development feature of the Atchafalaya Basin Floodway System, Louisiana project in St. Martin, Iberia, St. Mary, Iberville, St. Landry, and Pointe Coupee Parishes, Louisiana. The authorized goals of the Management Unit feature of the ABFS project are to improve water quality and interior water circulation; remove barriers to reestablish north to south water flow; provide input of oxygenated low temperature water; and reduce or manage sediment input into the interior swamp. Action is necessary due to the existing poor water quality resulting from the lack of internal circulation and oxygenated water inputs, and increased sedimentation. In addition if action is not taken, both deep-water and shallow water habitat utilized by fish and wildlife resources will continue to be lost, reduced, or degraded. The intended result of the proposed work is to prolong the life expectancy of the productive habitat (primarily aquatic and cypress tupelo habitats) by restricting or redirecting sediments, while simultaneously achieving a healthy water circulation pattern that would maintain or restore water quality and reestablish north to south water movement. The Henderson Lake Management Unit is hydrologically separate and independent from the Buffalo Cove, Flat Lake, Cocodrie Swamp and Beau Bayou Management Unit elements of the ABFS project. The authorized goal of the freshwater distribution structure element, of the Henderson Lake Area Atchafalaya Basin, Louisiana project is to provide water inflow to the Henderson Lake area and, together with the Henderson Lake Management Unit, restore overflow patterns to the extent practicable, and to encourage water movement through the Henderson Lake Management Unit for the benefit of the aquatic environment. The goals and objectives of the Recreational Development feature of the ABFS project are the development of facilities such as boat launching ramps for the provision of interior and peripheral access to the ABFS project area, including those lands acquired for the Public Access feature of the ABFS project, as well as the construction and operation of developed and primitive campgrounds, an interpretive facility and other facilities complementary to the enjoyment of outdoor recreational activities for the observation and utilization by the public of the fish and wildlife resources of the Lower Atchafalaya Basin Floodway. Public demand and expectations for the ABFS have increased due to an increased awareness and use of the vast ABFS natural resource, and the involvement of the CEMVN through management and part-ownership of the resource. The CEMVN will address public concerns for management of the Henderson Lake Management Unit, and recreational development opportunities within the ABFS, through an SEIS.
