Crews repair Gavins Point Dam from 2011 flooding

YANKTON, S.D. (AP) - Crews at Gavins Point Dam in Yankton are in the midst of fixing damage caused by record flooding on the Missouri River two years ago.  Crews have removed 3,000 tons of debris that hit the dam hard. The dam also lost 75,000 tons of rock on its west side.  The Army Corps of Engineers has already spent $2 million on improvements, including drilling holes into the concrete slabs to install pressure sensors.  The agency plans to spend another $10 million over the next two years on structural repairs to the 14 gates on the dam that will be repainted and get new cables.
