The Army Corps of Engineers will lower releases from Gavins Point Dam to 70,000 cubic feet per second on Thursday, a drop of 5,000 cfs, said Mike Swenson, a corps official.
Releases will be held at that level — more than double the usual amount for this time of year, well into July, he said. Releases will remain high into late November or early December.
The decrease of 5,000 cfs should allow the river to drop about 6 inches at most sites south of Omaha, barring significant rain, said Kevin Low, a hydrologist at the National Weather Service. In Omaha and Sioux City, Iowa, the drop should be more noticeable, he said.
This will be the first decrease in releases in almost a month. High releases — necessary to let out high runoff behind six massive dams — are being blamed for some downstream flooding, along with difficulties getting levees repaired. — Nancy Gaarder
