Missouri River Flooding 2011
June 4, 2011 by USA Post
Missouri River Flooding 2011, On Thursday, the Oahe Dam near Pierre launched an average of 85,000 cubic meters of water per second (cfs). On Friday, that level is approached to 100 thousand cubic feet. At the end of next week, which promises up to 150 thousand cubic feet. Prior to that, the album’s release was 59.000 cubic feet. “Pierre / Fort Pierre in the last week have been racing,” said Governor Dennis Daugaard. “About 2,000 homes were evacuated as more Oahe, and even as I speak there is heavy equipment operators trying to build dikes to protect the people.”
The governor stopped to make a presentation in 2011 of the State of South Dakota Girls in Slagle Hall University of South Dakota in Vermillion Friday. After his speech, he traveled to Dakota Dunes; another site of the flood is coming.
Of the approximately 1,100 homes in Dakota Dunes, “probably 800 to 900 of them” are in danger of flooding, Daugaard said.
“There are teams working 24 hours a day, all day, to build up levees. We build some dikes up to six to eight feet,” he said. “I do not know if we will get built in time, or if we built them, built all. So there are thousands of South Dakota residents who are fighting to protect their homes, because they can see the water coming.”
Traffic was closed on Thursday to assist in the evacuation and construction of dykes, Daugaard a measure expected to continue at least until Friday.
“There are fewer people and less in Dakota Dunes as people are evacuating, and our goal is to reach 1,100 of height in the dam upstream and downstream,” he said.
Daugaard said he has been asked many times over the last week if the flood is coming – that promises to raise the level of the river three to four feet – is the result of poor planning by the Corps of Engineers U.S. Army. UU. .
In short: No.
“Its Mother Nature is bringing this upon us. No man,” the governor said.
From May 1st Corps data indicated that all reservoir levels were normal, Daugaard said. However, the snow continues to accumulate in the Rocky Mountains and rain upstream, has been much higher in the last two weeks.
“There were parts of the Black Hills, which has 10 inches of rain. There were parts of Montana that has 15 inches of rain,” Daugaard said. “Ten and a half million acre-feet of water fell. That means that 10 1 / 2 acres of land covered by the foot (of water). This is how rain fell in about two weeks.”
That is 130 to 140 percent above average, he said.
Added to this, the snowpack in Montana has not melted in a large degree.
“I talked to (the governor of Montana, Brian Schweitzer) yesterday, and said: ‘The Yellowstone River in Montana usually peaks in the flow of the second week of June. It was out of its banks for two weeks, and snow has not even started yet, “Daugaard said.
As a result, the reservoirs are now full.
“The Oahe reservoir is one foot from the top,” Daugaard said. “I think it’s less than a foot from the top. If there is wind, blowing over the landfill.”
The governor inspected the levees in Pierre Pierre / Fort Vermillion before going to Friday morning, and said they are looking good.
“We’re in pretty good shape in terms of elevation, and water will not reach 150 for a week, so I say that one or two days we do everywhere in Pierre and Fort Pierre,” he said. “As the contractor realized that they were able to achieve much, have expanded the dam to the north and tried to protect more homes. So, are working on an expanded project.”
Once construction is complete, the mission will shift to monitoring the levees and protection of neighborhoods, including emergency response if problems are detected, the governor said.
“We will be keeping Black Hawk helicopters, both Pierre Pierre / Fort Worth and Dakota Dunes so we can make an emergency evacuation of people who otherwise refused to leave, and now is necessary because of a dam or a problem with the levees, “which, he said.
These helicopters can lift between 2.1 tonnes and can bring in rocks or sand if there is a breach that can be connected, Daugaard said.
“They’re the finger in the dike,” he said.
In general, the work has gone well.
“Until now, we just had an injury,” Daugaard said. “The citizen is volunteering, God bless you, and were struck by a Bobcat and broke both his legs. But there have been no deaths. That is the danger of what might happen when the water rises significantly in the week coming, so we really need to keep these people in our prayers, we hope to maintain the levees … and keep all of South Dakota insurance. ”
Daugaard said he felt it was important to visit the sites of flooding potential.
“You can read about something or see something on TV, but nothing compared to being there,” he said.
The governor said the people he has met have been very strong in the face of impending disaster.
“People are very self-sufficient and understanding. I do not see much of the blame for investigation or complaint,” he said. “I see a lot of hard work and determination to take full advantage of what limited time we have. … People are working long hours to protect and so many people who work long hours to protect others.”
Daugaard as an example the number of school sports teams like the University of South Dakota and South Dakota State University – as well as ordinary citizens – who have donated their time to help fill sandbags.
“I talked to a woman who was a whole group of strangers sandbags to her the night that has just appeared,” he said. “I am proud to be one of South Dakota.”
