[PAR] [TLE] Gavins Point Dam [SEP] Gavins Point Dam is a hydroelectric dam on the Missouri River in the U.S. states of Nebraska and South Dakota.  Built from 1952 to 1957, it impounds Lewis and Clark Lake.  The dam is on the Nebraska-South Dakota border, west of Yankton, South Dakota.  During the 2011 Missouri River Flood the dam was damaged by debris and a significant portion of rocks were dislodged from its upstream side.  The U.S. Army Corps of Engineers soon began repairs to the dam and its spillway gates.  Pressure sensors were also installed in concrete portion of the dam. [PAR] [TLE] 2011 Missouri River Flood [SEP] The 2011 Missouri River floods was a flooding event on the Missouri River in the United States.  The flooding was triggered by record snowfall in the Rocky Mountains of Montana and Wyoming along with near-record spring rainfall in central and eastern Montana.  All six major dams along the Missouri River released record amounts of water to prevent overflow which led to flooding threatening several towns and cities along the river from Montana to Missouri; in particular Bismarck, North Dakota; Pierre, South Dakota; Dakota Dunes, South Dakota; South Sioux City, Nebraska, Sioux City, Iowa; Omaha, Nebraska; Council Bluffs, Iowa; Kansas City, Missouri; Jefferson City, Missouri, as well as putting many smaller towns at risk.  According to the National Weather Service, in the second half of the month of May 2011, almost a year's worth of rain fell over the upper Missouri River basin.  Extremely heavy rainfall in conjunction with an estimated 212 percent of normal snowpack in the Rocky Mountains contributed to this flooding event.
