Massive Flooding in the Midwest is only the beginning as record snow and water hit the states this winter.












Massive Flooding in the Midwest is only the beginning as record snow and water hit the states this winter.


It's the worst flooding parts of the Midwest have seen in decades, where several states are battling the aftermath of a powerful "bomb cyclone" which swept through the region last week, bringing blizzard conditions, hurricane-like winds, snow and heavy rain.

The powerful storm pushed some waterways, including the Missouri River, to record levels in South Dakota, Iowa and Minnesota.

Marc Chenard, a meteorologist with the National Weather Service, told NPR many areas will remain water-logged for days.

"All the rivers respond differently, have different time scales that they flood and then recede. A lot of the rivers are going to remain in flood into the weekend, and some into next week," Chenard said. "Eventually as we head into next week, we should see more and more of the rivers start to recede below flood stage."

Iowa, Wisconsin and Nebraska have all declared states of emergencies.

As rivers spill over their banks and through local communities, the rising waters are setting records.

In Nebraska, Gov. Pete Ricketts said nearly every part of the state is experiencing historic flooding.



Nebraska has experienced historic flooding and extreme weather in nearly every region of the state. Today, Speaker Scheer of Norfolk and I surveyed some of the flooding.

Nebraska has deployed helicopters to assist in rescuing those trapped by the high waters, and boats for travel across washed out roads. CNN reported that some people who were rescued suffered from hypothermia, and had to be transported to the hospital.

The Omaha-Valley Weather Service office said a levee was breached in Nebraska's Dodge County. "This is an extremely dangerous and life-threatening situation," the weather service warned. "Do not attempt to travel unless you are fleeing an area subject to flooding or under an evacuation order."

With flood waters rising, officials were monitoring for damage at the Cooper Nuclear Station, south of Omaha, which serves about half a million customers. Mark Becker, spokesperson for the Nebraska Public Power District told NPR the plant will continue operating for the foreseeable future. "If we get to the next threshold, the plant would go to a shutdown," Becker said.

"A week ago, my backyard had a foot of snow in it. It's warmed up. The ground is frozen still. The snow is melting, and we've had some torrential rains, and that's created torrential flooding," Becker told NPR.

In Wisconsin, Governor Tony Evers said flooding was impacting "homes, businesses, and cities and towns" across the state.

Lori Getter of the Wisconsin Emergency Management spoke with NPR. "We're trying to get a handle on the situation with the flooding across the state, but two days ago, and even yesterday, we were evacuating people because of the rising waters," Getter said.

A bomb cyclone occurs when there is a rapid drop in atmospheric pressure. The massive storm moved into Canada on Friday.

Saturday flood updates: Offutt fights rising waters. Evacuations near Ashland. Eppley camp ruined. And more.

From staff reports
1 hr ago


Airmen at Offutt Air Force Base filled up to 100,000 sandbags in a last-ditch effort to block flood waters that are covering much of the southeastern part of the base.


An aerial photo, posted by 55th Wing Commander Col. Michael Manion on his Facebook page, showed the Missouri River had crept up to the southeast end of Offutt's single runway. A lake, campground, and baseball fields were under water, and several buildings south of the runway are surrounded. Water also is coming toward the StratCom Gate to the airbase on Capehart Road.


"Water is entering from the river and through the storm drains," Manion wrote in the post Saturday afternoon. "Several buildings including the (55th) Wing Building are inundated with water. We continue to work as rapidly as possible to improve water defenses around critical infrastructure."


Several RC-135-variant reconnaissance aircraft were flown out to other bases Saturday evening.


Photos showed water had reached the hangar that houses the 595th Command and Control Group, which operates the Air Force's fleet of four E-4B Nightwatch airborne command post jets.


The Air Force flew in a 740-foot length of 4-foot Aqua Dam barriers from Louisiana to deploy around another building that houses the 55th Wing's expensive flight simulators.


Meanwhile, Manion said power to the base has not been interrupted.


The water was expected to crest near the base late Saturday, Manion said.

A flood-related fatality in Iowa


One flood-related fatality has been confirmed in Fremont County, Iowa.


Fremont County Emergency Management Director Mike Crecelius said one person drowned Friday night after a car drove around a barricade and quickly took on water near Riverton.


The car had three occupants inside. After driving around the barricade, the car was swamped with water and it started to float. One of the passengers struggled to get out of the water and died on the way to a local hospital. Another escaped by climbing a tree, and a third was able to get out of the water entirely.


Crecelius​ didn't know the name, age or gender of the person who died.


"When they say 'Turn around, don't drown,' the barricades, they're there for your safety," Crecelius said. "There's a reason for them."

Salvation Army's Gene Eppley camp is 'total loss' after flooding


The Salvation Army's Gene Eppley Camp, which is just south of Omaha near U.S. Highway 75, looks to be a total loss after the nearby Platte River flooded.


The camp sits on the north bank of the Platte between Bellevue and Plattsmouth. It was inundated by floodwaters on Saturday, a Salvation Army spokesman said.


"Water levels have reached all the way up to the roofs of the cabins and other buildings," said Todd Andrews, the spokesman.


An initial survey of the property indicates the Eppley camp, which sits on 118 acres, is a "total loss," the Salvation Army said.


Some 3,400 people were scheduled to use the camp this year, which for decades has been a year-round camp.


The Salvation Army said it is looking for volunteers to assist with flood-relief efforts. To volunteer, people can call 402-989-6050. People also can donate by going to a special website set up for flood disaster relief.

U.P. evacuates people from Waterloo and Valley using rail lines; curfew enacted


On Saturday afternoon, Union Pacific began to transport people who were evacuating the flooded Waterloo and Valley areas to the safety of Elkhorn.


Evacuees were being transported by so-called high-rail vehicles along U.P.'s rail lines. They were being taken to Elkhorn Middle School.


Douglas County, the city of Omaha and other government agencies working under the area's Unified Command for emergencies were working with Union Pacific to arrange the evacuation, according to a county spokeswoman.


At the school, kennels and pet food will be available from the Nebraska Humane Society, as will services from the American Red Cross. Medical and behavioral health professionals also have been requested, the county said. The Omaha Police Department will provide security.


Meanwhile, the Unified Command said an 8 p.m. curfew would be enacted for Valley and Waterloo. The U.P. operations also will stop at 8 p.m. Rescues also will stop at that time, the county said, so if residents haven't been rescued from their homes by then, they should "shelter in place" until morning. Rescues will begin again on Sunday at sunrise, the county said. Residents with emergencies still can call 911.

Nebraska nuclear power plant along Missouri River continues operating


The Cooper Nuclear Station near Brownville, Nebraska, along the Missouri River still is operating at 100 percent on Saturday evening, the Nebraska Public Power District said.


The plant continues to operate under a "Notice of Unusual Event" with its federal regulator as the Missouri River is elevated, though water levels near the plant have been going down, NPPD said.


"Water levels in the river have had no impact on operations and there is no indication of leakage at the facility," the power district said.

No flooding in city of Columbus as residents sandbag


The Loup River has dropped by about six feet since yesterday, said Columbus and Platte County emergency management director Tim Hofbauer.


There is no flooding within the city of Columbus, he said. Still, residents have been sandbagging the area for weeks, especially around the lake areas. "The levee helped in Columbus," Hofbauer said. "We love our levee."


The Nebraska Task Force One swift water rescue team worked Thursday and Friday, and Nebraska National Guard medevac units arrived in the area around 7 p.m. Thursday. The unofficial rescue count is 48, Hofbauer said, but he's not sure what the number is for pet rescues.


"Our biggest concern out in the rural areas is that the county roads are extremely soft and muddy," Hofbauer said. If anyone has to travel, he advised them to use extreme caution and not drive through any water.

M.U.D. monitoring river conditions; drinking water still safe, utility says


The Metropolitan Utilities District of Omaha, which provides water to much of the Omaha metropolitan area, is monitoring conditions on the Missouri and Platte Rivers as flood waters rise and spark some concerns about contaminants.


The utility said drinking water is safe. It still meets or exceeds all state and federal standards based on more than 1,000 tests a day, the utility said.


"Precautions are in place to protect the reliability of our water treatment and distribution systems," the utility said in a statement. "We are closely monitoring all of our facilities and have contingency plans in place to address any issues that might occur."


In Lincoln, the city said its water also was safe. The Lincoln Water System sources its water from ground water, which isn't at risk from contamination in a flood, the city said.

Governor: Evacuate now if you're in the path of floodwaters


Gov. Pete Ricketts said Saturday morning that what's happening is an ominous sign for those downstream, who are likely to face flooding.


Ricketts and other state officials said people should consider leaving preemptively — don't wait to be told to evacuate.


And the National Weather Service said areas like Ashland and Plattsmouth still face trouble Saturday as the Platte and Missouri Rivers continue to rise.


“We’re just smashing some records on the big boys, the Missouri and the Platte,” said meteorologist Jeremy Wesely.


Water levels on the Platte, Missouri and Elkhorn Rivers have crested or are projected to crest Saturday.


In Sarpy County, a string of river and lake communities near Bellevue and the Platte River were evacuated, including Hanson Lakes, Chris Lake and Betty Lake. Residents of Hawaiian Village, north of Papillion, and Villa Springs, south of Springfield, were urged to evacuate immediately to avoid being stranded by rising waters and road closures.


Water levels were expected to keep rising over into Sunday and possibly Monday.

In Plattsmouth, positive attitudes as Missouri River gushes over banks


People walked in twos and fours from the Plattsmouth business district on Main Street to the spot where the Missouri River has gushed over its banks.


“Crazy, isn’t it?” said a woman walking up to where the water lapped onto the street.


Ed Olson acted as a narrator of the scene.


“This is a cornfield,” he said, pointing to the small sea in front of him. He motioned to some submerged trailers, RVs and summer homes.


“Now it’s a marina,” Olson said.


The day was sunny and cool.


“Pretty day for a flood. You’ve got to stay positive,” Olson said.


North of Plattsmouth two deer drank from a pool that had seeped into a farmfield.

Nebraska rivers hit record levels


A few rivers have hit record levels as National Weather Service meteorologists caution that water levels will continue to rise for the next several days.


No additional moisture is expected in the coming days that will add to the totals, other than a low chance of snow Monday night, said weather service meteorologist Dave Eastlack.


nd of receding until mid- or late next week," he said.
