HAMBURG, Iowa (Reuters) – Federal officials increased water releases from two South Dakota dams on Saturday to make room for expected potentially heavy rains through early next week, adding to flooding woes along the Missouri River.
The U.S. Army Corps of Engineers water releases from five dams in North Dakota and South Dakota had already about doubled prior records to relieve reservoirs swollen by heavy winter snows and spring rainfall at the river's Montana headwaters.
With severe storms expected over the next four or five days that could dump up to 4 inches of rain in some areas, the Corps has started to increase flows by nearly 7 percent at the Oahe Dam above Pierre, South Dakota's capital, and the Big Bend Dam just downstream.
"It's going to be a widespread heavy rainfall event and obviously will have a big impact on the Missouri River Valley for the next four or five days," said Bruce Terry, a senior National Weather Service forecaster.
