Gavins Point Dam
June 3, 2011 by staff
Gavins Point Dam, Harrison, Emergency Management Director Larry Oliver County warned those present at the emergency meeting on June 1 that a very, very serious situation has the potential to develop over the next week in Harrison County.
Due to the increased release of Gavins Point Dam in South Dakota, areas south along the Missouri Valley are projected to see flood damage occurs to continue to grow and last for several months.
According to Oliver, at midnight on June 1 cubic 98,000 meters per second of water was being released from Gavins Point Dam. By June 14 this is expected to increase to 150,000 cubic meters per second. In Sioux City today, the river level was 28 feet, which is projected by the Corps of Engineers to increase to 35 feet by 14 June.
“This potential is unknown at this time,” said Oliver. “The system of dams on the Missouri River has not been tested at these levels during this period of time. There is a potential for a very, very serious event.”
The meeting was called to urge city and county officials to begin preparations and to notify residents. Oliver advised officials to arrive at a plan to notify residents for a possible evacuation for residents living in flood zones planned to make plans to move.
“This is not an event that will be over next week,” said Oliver. “I’m listening to months, perhaps until December. The most important thing is that we want the communities to start thinking for themselves. We must help ourselves,” said Oliver.
Harrison County Supervisor, Chair, Bob Smith said the county resources are used best.
“But we can not be the ultimate problem solver,” said Smith. “People have to plan for themselves.”
It’s inevitable, “said Harrison County Sheriff, Pat Sears.” It’s coming. We will be here to help, but people need to prioritize what needs to be done. ”
It was also stressed to maintain documentation of time and expenses related to the flooding event to aid possible future of FEMA.

Harrison and Monona County officials are encouraging people who live along the Missouri River to make evacuation plan to protect their assets and property due to the rising waters of the Missouri River.
The Missouri River is currently at or above flood stage. The levels are the result of the release of water from Gavins Point Dam in South Dakota. Extraordinary snow melts and spring rains are occurring in the catchment area of?? Gavins Point Dam and filled the reservoir to dangerous levels, forcing the Army Corps of Engineers to increase the flow of water at record numbers. The Army Corps of Engineers is forecasting even greater quantities of the release of the summer, which will cause river levels to be at even higher levels.
Campers, mobile homes, equipment, propane tanks and fuel tanks must be relocated to safe areas to prevent dragged downstream.
Local authorities would like to remind citizens that driving through water running across the road is dangerous. Rapid movement flows and landslides are extremely dangerous and should not try to cross them.
State officials cannot enter into areas of risk to the rescue once the evacuation has been ordered.
Due to continued increase in the Missouri River, DeSoto RefugeFest scheduled for Saturday, June 4, has been postponed indefinitely. With the continued high water expected in the fall, the public will be notified when conditions allow for the rescheduling of RefugeFest.
