Big Bend Dam/Lake Sharpe Master Plan, Missouri River, South Dakota: Update of Design Memorandum MB-90.

摘要

The Big Bend project was authorized by the Flood Control Act of 1944, Public Law 534, 78th Congress, 2nd session, along with four other Missouri River main stem projects -- Gavins Point, Fort Randall, Oahe, and Garrison. These five reservoirs are elements of a plan for the development of the Missouri River main stem system (Figure 1-1). This main stem plan is a component of the comprehensive river basin development program in the Missouri River Basin, the Pick-Sloan Plan, also authorized by the Flood Control Act of 1944. Fort Peck Dam, located in northern Montana, was constructed prior to the Pick-Sloan Plan but is operated as part of the Missouri River main stem system. The Big Bend project (Figure 1-2) was authorized for flood control, navigation, hydropower, fish and wildlife, recreation, municipal and industrial water supply, irrigation, and other purposes. This updated Master Plan reaffirms land classifications and management practices similar to those already in effect and provides for recreational opportunities while maintaining the integrity of the natural resources. The Corps of Engineers (Corps) is the steward of the lands and waters at Corps water resources projects. Its Natural Resources Management mission is to manage, conserve, and improve these natural resources and the environment while providing quality public outdoor-recreation experiences to serve the needs of present and future generations. In all aspects of natural and cultural resource management, Corps managers promote awareness of environmental values and adhere to sound environmental stewardship, protection, compliance, and restoration practices.
