I grew up around Gavins Point Dam stretching across the boundary of Nebraska and South Dakota. Severe flooding on the upper Missouri may be a rare event, but harsh criticism of the the US ARMY corp of engineers isn't. For decades, stakeholders up and down the river have waged a fierce struggle over how the corps has managed water releases from the great 6 Missouri River reservoirs -- struggles triggered equally by periods of low water as this year's high water.

Monday June 27, 2011 - MISSOURI RIVER 2011 FLOODING UPDATE

Omaha.com | Flood test is not over for Ft. Calhoun nuclear plant near Omaha and Cooper Nuclear Plant is planning on operating all summer


COOPER NUCLEAR PLANT NEAR BROWNVILLE, NEBRASKA


Published Monday June 27, 2011

Two outside lines of defense against flooding failed Sunday at Fort Calhoun Nuclear Station, shifting the plant to backup electricity for 12 hours.

On Monday, the Omaha Public Power District was studying whether it could patch and refill the temporary water dam that burst. When the dam ruptured, it allowed floodwater to fill in around the plant to a depth of more than two feet, said OPPD spokesman Jeff Hanson.

Sunday's development offers more evidence that the relentlessly rising Missouri River is testing the flood-worthiness of an American nuclear power plant like never before. The now-idle plant, 19 miles north of Omaha, has become an island. And unlike other plants previously affected by high water, Fort Calhoun faces months of flooding.

Also on Monday, the head of the nation's nuclear regulatory agency, his lieutenants and congressional representatives toured the plant.

Sioux City Journal | Corps doesn't expect to use SD Oahe Dam's spillway gates (which is an earthen channel instead of concrete and subject to erosion)




PIERRE, S.D. (AP) Monday, June 27, 211 8:16 am — The Corps of Engineers says that despite heavy weekend rains in parts of the Missouri River basin it expects the Oahe Dam reservoir in South Dakota to peak just a few inches below the top of the emergency spillway gates.

That means the agency wouldn't have to use the spillway, which is an earthen channel instead of concrete and subject to erosion. Jody Farhat with the corps tells South Dakota Public Radio that officials are trying to avoid using the spillway. The reservoir level is less than half a foot from the top of the gates because of heavy spring snowmelt and rains.

KCCR radio reports that the corps plans to increase Oahe releases to 160,000 cubic feet per second by Friday, then begin dropping them back the following Tuesday.

Flood wall fails at Fort Calhoun
Omaha World Herald - June 26, 2011 Floodwaters surrounded several buildings at the Fort Calhoun Nuclear Station early Sunday morning after a water-filled wall collapsed. The 2,000-foot berm collapsed about 1:25 a.m. Sunday due to “onsite activities,” OPPD officials said. The Aqua Dam provided supplemental flood protection and was not required under NRC regulations.

Flood berm collapses at Nebraska nuclear plant
Associated Press June 26, 2011 The berm's collapse didn't affect the reactor shutdown cooling or the spent fuel pool cooling, but the power supply was cut after water surrounded the main electrical transformers, the NRC said. Emergency generators powered the plant until an off-site power supply was connected Sunday afternoon, according to OPPD.

Flood berm collapsed after being punctured by an unidentified piece of machinery: OPPD
(CNN) -- A water-filled berm protecting a nuclear power plant in Nebraska from rising floodwaters collapsed Sunday, according to a spokesman, who said the plant remains secure. Some sort of machinery came in contact with the berm, puncturing it and causing the berm to deflate, said Mike Jones, a spokesman for the Omaha Public Power District (OPPD), which owns the Fort Calhoun plant.

Flooding: The worst is yet to come
Omaha World Herald - June 26, 2011 Imagine roughly 55 million acres — the entire surface of Nebraska and southwest Iowa — covered in a foot of water. Now imagine trying to funnel all that water down a drainage canal surrounded by airports and homes, businesses and farms. You can begin to grasp the unprecedented, slow-developing danger facing folks from Montana to Missouri from the Great Flood of 2011.

Concern at Nebraska Reactors as Floodwaters Rise
NYT - BROWNVILLE, Neb.June 26, 2011 — Like inhabitants of a city preparing for a siege, operators of the nuclear reactor here have spent days working to defend it against the swollen Missouri River at its doorstep. On Sunday, eight days after the river rose high enough to require the operators to declare a low-level emergency, a swarm of plant officials got to show off their preparations to the chairman of the Nuclear Regulatory Commission.
