Lake Sakakawea is a reservoir in the north central United States, located in the Missouri River basin in central North Dakota. Named for the Shoshone-Hidatsa woman Sakakawea, it is the largest man-made lake in North Dakota and the third largest in the United States, after Lake Mead and Lake Powell. The lake lies in parts of six counties in western North Dakota: Dunn, McKenzie, McLean, Mercer, Mountrail, and Williams. A map centered on the Van Hook Arm of the lake perhaps better shows its westward extent from its origin at the Garrison Dam. It is located about from Bismarck; the distance by the river is about . The lake averages between in width and is wide at its widest point (Van Hook Arm). Lake Sakakawea marks the maximum southwest extent of glaciation during the ice age. The reservoir was created with the completion of Garrison Dam in 1956, the second (and largest) of six main-stem dams on the Missouri River built and managed by the U.S. Army Corps of Engineers for flood control, hydroelectric power, navigation, and irrigation. The creation of the lake displaced members of the Fort Berthold Indian Reservation from the villages of Van Hook and (Old) Sanish, forcing the creation of New Town, White Shield, and Mandaree. Incidentally, one name that had been proposed for New Town was ''Vanish'' (a portmanteau of the two previous towns' names). A third reservation town, Elbowoods (Arikara: hiswíkat ()), where the agency headquarters, boarding school, hospital and jail were located, was also lost to the lake. These three towns are commemorated in the names of the three campground sections at Lake Sakakawea State Park, a state park located adjacent to Garrison Dam. Lake Sakakawea is also home to many summer camps, including Triangle Y Camp and Camp of the Cross. During a training flight in 1969, a U.S. Air Force F-106A Delta Dart (59-0014)〔(【引用サイトリンク】publisher=Joseph F. Baugher )〕 from Minot AFB, about sixty (100 km) miles north of the dam, crashed into the western portion of the lake on March 10. The pilot ejected safely to land and the plane sank below the frozen surface. It was not located until over 35 years later, in September 2004, after an extended search by a local surveyors' group. ==Statistics== * Maximum water storage: * Maximum water depth: at the face of the dam * Normal surface area:〔Based on elevation MSL.〕 * Normal length:〔 * Normal shoreline:〔 Source:〔(U.S. Army Corps of Engineers )〕 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「Lake Sakakawea」の詳細全文を読む スポンサード リンク
