The Pick-Sloan Flood Control Act of 1944 (P.L. 78–534), enacted in the 2nd session of the 78th Congress, is U.S. legislation that authorized the construction of numerous dams and modifications to previously existing dams,〔(Flood Control Act of 1944 ), Digest of Federal Resource Laws of Interest to the U.S. Fish and Wildlife Service〕 as well as levees across the United States. Among its various provisions, it established the Southeastern Power Administration, and led to the establishment of the Pick-Sloan Missouri Basin Program. The Pick-Sloan legislation managed the Missouri River with six intents: hydropower, recreation, water supply, navigation, flood control and fish and wildlife. Over 50 dams and lakes have been built due to this legislation, not just on the mainly affected river but also on tributaries and other connected rivers. Nebraska, as an example, has seen more than eight new lakes created due to the damming of the Missouri and tributaries. The Act was signed by President Franklin D. Roosevelt on December 22, 1944. It was named for General Lewis A. Pick, head of the Army Corps of Engineers, and W. Glenn Sloan of the Interior Department's Bureau of Reclamation. ==Effect on American Indians== The act transferred ownership of large parcels of land from around the Missouri River, more than 20% of which was owned by Native Americans, to the Corps of Engineers. The Lakota, Dakota and Nakota tribes lost . The Three Affiliated Tribes, specifically, lost in their Fort Berthold Reservation due to the building of the Garrison Dam. This project caused more than 1,500 American Indians to relocate from the river bottoms of the Missouri river due to the flooding. The project has successfully controlled flooding throughout the Missouri river basin, provided water for irrigation and municipalities, generated baseload power throughout the central US, and is a truly great place for fishing, hunting, and watersports. A possible down side. The Missouri River (The Big Muddy), dumped millions of cubic feet of soil into the Mississippi River every year, which, in turn deposited this silt into the gulf and formed a string of barrier islands. When the silt was eliminated this island building stopped. Biologists sounded the alarm in the 1970s. By the 1990s the barrier islands were pretty much gone. Without those islands Louisiana was left unprotected from storm surges and oil spills 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Flood Control Act of 1944」の詳細全文を読む スポンサード リンク
