Corps of Engineers Continues Assistance in Missouri River Flood Fight (ContributorNetwork)

The Army Corps of Engineers continues its efforts to reduce the damage created by the record water levels along the Missouri River and its tributaries. Six major dams and hundreds of miles of levees have been tested by the historic runoff the river basin is experiencing. Fifteen levees have been breached or overtopped at this time along the lower Missouri.

Main Stem Dams

Fort Peck: The Fort Peck reservoir is at capacity. The current plan is to lower discharges during the remainder of July. The reservoir is currently 2.5 feet below its record height in June.

Garrison: The Garrison reservoir is above the height of the spillway when closed. The open gates are providing surcharge storage and allowing the reservoir to hold additional flood water. Discharges are expected to be reduced slightly during the remainder of July.

Oahe: The Oahe reservoir is very close to capacity. The Corps plans to reduce the water discharge slightly during the rest of the month of July.

Big Bend: The reservoir created by the Big Bend dam is slightly below capacity at this time. Discharges have been reduced by about ten percent for July from the record amount set in June.

Fort Randall: The Fort Randall reservoir is continuing to fill though still below capacity. The Corps plans to increase discharges to offset the increase of water entering the reservoir.

Gavins Point: The reservoir remains about three feet below its record, set in June. Discharges will remain at 160,000 cubic feet per second, a record output, for the foreseeable future.

Lower Missouri River Levees

Federal Levees: 48 federally controlled levees line the Missouri River and its tributaries downstream of Rulo, Kan. Only one has breached or overtopped, at Fort Leavenworth, Kansas. One additional levee, near St. Joseph, MO, is within two feet of overtopping.

Non-Federal Levees: These 100 levees currently have a number of issues. Fourteen of them have been breached or overtopped. An additional 26 are within two feet of being overtopped.

The levees are under continued pressure from the flood waters. Most are saturated with water, making their integrity an issue. The Kansas City Star quotes a number of experts who expect additional levee failures. Most of the ten states in the Missouri River basin have activated National Guard units for flood fighting duties, including patrolling levees.

Future of levee blown to save Illinois town unclear, Corps says (Reuters)

SIKESTON, Mo (Reuters) – The federal government has not decided whether it will rebuild the Mississippi River levee intentionally destroyed last month to relieve flooding in Cairo, Illinois and other towns, an official said on Thursday.

Jim Pogue, a spokesman for the Memphis District of the Army Corps of Engineers, told Reuters a final decision on the future of the Birds Point-New Madrid levee near here would not come "for months."

Pogue said the Corps was studying the performance of the whole system of levees and floodways along the Mississippi after this spring's record flooding and any decision on Birds Point-New Madrid would be made as part of that larger study.

He said it has been a "challenge" to find money to replace levees along the river and the Corps had been working with Congress to identify possible revenue sources.

The levee at Birds Point-New Madrid was deliberately destroyed by the Corps on May 2, flooding over 100,000 acres of prime farmland in Missouri. Some farmers sued the Corps over the decision to blow the embankment, which lowered the water level on the Mississippi by allowing water to rush into a spillway that had not been used since 1937.

A snowy winter and rainy spring have caused record flooding on the Ohio, Mississippi and Missouri Rivers this year.

To cope with Mississippi water levels that approached or beat records set in 1927, the Corps also opened up the Morganza and Bonnet Carre spillways last month. It was the first time that all three floodways were opened in the same year.

In South Dakota, some blame Corps for flood threat (AP)

FORT PIERRE, S.D. – Sitting atop a 6-foot wall of white sandbags hastily stacked to protect his home from the rising Missouri River, 82-year-old Helmet Reuer doesn't buy the official explanation that heavy rains caused a sudden flood threat.

Along with his neighbors in an upscale section of Fort Pierre, Reuer thinks the U.S. Army Corps of Engineers blew it, waiting until too late to begin releasing water through the Missouri's six dams to give itself a cushion against potential flooding.

"It's human error," Reuer said as rising water neared his trim gray house.

Corps officials insist otherwise. They say they were in good shape to handle spring rain and melt from a massive Rocky Mountain snowpack until unexpectedly heavy rains of 8 inches or more fell last month in eastern Montana and Wyoming and western North Dakota and South Dakota.

"This is just a massive rain that fell in the exact wrong place at the exact wrong time," said Eric Stasch, operations manager at Oahe Dam, the huge structure that controls the Missouri's flow just above Fort Pierre and nearby Pierre, South Dakota's capital.

Crews have worked urgently all week to build up levee protections for the two cities, and say they expect to have 2 feet to spare. But Gov. Dennis Daugaard advised people in neighborhoods nearest the river to leave voluntarily in case levees don't hold, and hundreds have done so after a hectic week of moving possessions and adding sandbags around their houses.

They face weeks out of their homes until the river begins cresting in mid-June, with high water expected to linger for up to two months. The small town of Dakota Dunes, S.D., in the southeastern tip of the state, has also erected levees, as has Bismarck, N.D., though the situation is less serious there.

"I think they screwed up royally," former Gov. Mike Rounds said of the Corps, as he moved some possessions from the riverbank house he and his wife built and moved into after he left office in January. "I think they forgot their No. 1 mission, and that's flood protection."

People here were prepared for some higher flows, but many were startled when the Corps announced May 26 it needed to release water much faster than expected from the dams in Montana and the Dakotas.

Jody Farhat, chief of Missouri River Basin water management in the corps' Omaha District, said the agency made no mistakes and has managed releases in accordance with its manual. She said conditions on May 1 indicated peak releases at only a third of what they're now projected, and the reservoir system had full capacity to deal with flood control at the start of the runoff season. All that changed with the record rainfall in the upper basin and additional snow in the mountains, she said.

Farhat said heavy runoff from last year was released before the start of this year's runoff season, and discharges this spring were above normal even before the heavy rainfall upstream.

Corps officials declined a request for a one-one-one interview and provided some information by email, but in a teleconference Thursday, Farhat said the reservoirs had reached the desired levels before snowmelt was to begin.

"And what happened was we had this incredible rainfall event," Farhat said. "That was a rainfall event in May, and that was the game-changer in terms of system operations."

People who live in the flood-threatened areas say this wasn't supposed to happen.

The Missouri River dams were built to control periodic spring flooding and provide hydropower, irrigation and other benefits after Congress passed the Flood Control Act of 1944. Fort Peck Dam, in northeastern Montana, was already operating in 1940 and Oahe, a massive reservoir that runs from North Dakota to the dam near Pierre in central South Dakota, was completed in 1962. Big Bend, about 60 miles downstream from Oahe, was the last dam finished, in 1964.

This is not the first fight over Missouri River water management, but the dispute has more often been about too little water. A series of lawsuits was filed during a prolonged drought that started about a decade ago. Upstream states wanted more water left in the reservoirs to support a growing sport fishing industry, while states downstream wanted more water to support barge traffic on the free-flowing stretch from Sioux City, Iowa, to St. Louis.

The U.S. Supreme Court declined to consider the legal fight in 2006, leaving intact a federal appeals court ruling that said navigation trumps upstream recreation and other interests when the Corps of Engineers manages the river.

In Montana, officials in downstream communities said some people faulted the Corps for not releasing water earlier from Fort Peck Dam, the first in the series of water-control structures on the river.

But Roosevelt County Commissioner Gary MacDonald said he was reluctant to blame the federal agency.

"That's the sentiment here of why did they wait," MacDonald said. "There's no better person for the average John Doe to blame out there than the Corps. They're taking the brunt of it because they're controlling the flow."

Back in South Dakota, Daugaard also declined to criticize the Corps, saying he had seen "no evidence that they're working other than in good faith" to deal with the situation.

At Oahe Dam, the quickening pace of the water releases through rarely used gates — more than 100,000 cubic feet per second and building — makes for a foaming, thundering spray that brought spectators by the carload before it was closed for safety reasons. But many here have no time to appreciate the river's power.

"I'm tired and I'm sick," Mike Richardson said as he loaded household items into a trailer to move them from his Fort Pierre house to higher ground. "I'm better off than a lot of people, I know, but I still can't help but feel sorry for myself. ... Somebody really dropped the ball on this deal."

Windsor Genova - AHN News News Writer

Morganza, LA, United States (AHN) - Crews from the U.S. Army Corps of Engineers opened two more gates of the Morganza Spillway on Sunday to prevent Baton Rouge and New Orleans from being flooded by the rising Mississippi River.

The opening of the two gates bring to four the total number of gates opened to divert flooding to farmlands and rural areas in Louisiana as water flowing in the Mississippi River reached the dangerous level of 1.5 million cubic feet per second.

Some 40,000 cubic feet of water was coming out per second from the opened gates on Sunday and moving to the Atchafalaya Basin. The water will eventually flow into the Gulf of Mexico.

The first two bays of the spillway were opened for the first time since 1973 on Saturday afternoon and evening. A total 31 of 125 gates will be opened to ease pressure from the Mississippi River.

Up to 3,000 miles of land is expected to be flooded and 25,000 people affected with the opening of 31 Morganza Spillway gates.
