Here are some of the friendships that come after the destruction.
& # 39; Any shoes are better than wet shoes & # 39;
When Addy Tritt, 25, noted her local discount store was shut down, she decided to buy their entire store.
Mrs Tritt then donated the 204 pairs of shoes, valued at $ 6,000 (£ 4,555) to families affected by the floods.
"I wanted them to go to people who actually needed them," said Tritt to CBS News.
After spending two hours negotiating with the store's headquarters, Tritt paid only $ 1
By Ms. Tritt's feature was 162 pairs of baby shoes, two were men's shoes and the rest were women, according to the Associated Press.
"All shoes are better than wet shoes," said Tritt. "If people feel lost, they must volunteer and donate. It gives me such a fulfillment and I want others to feel the way I do."
The shoes were part of a shipment to Nebraska farmers arranged by a local student farming group.
Nebraska Governor Pete Ricketts said the farmers were some of the worst hit by "the most widespread destruction we have ever seen in our state's history".
Island hopping in Nebraska! & # 39;
With many roads in the region made impossible by flood, some volunteers took to heaven to save stranded residents.
Adam Marshall, has been a private pilot for three years, and when he began receiving calls for help from people caught in Fremonts nearby town, he fired his small propeller plane.
Marshall told CNN that he has made more than 30 trips and described it as "island hopping in Nebraska".
"My phone just started blowing up and I told my wife," I think I'm going to be away for a few days. "
" I transported the entire Midland University dance team to Omaha so they would not miss their commercial flight and a woman named Allie who has five children and was cut off from her family, "he said.  Surrounded by rising river water, Gary Fouraker was shaken at the hospital when doctors suspected he had blood clots in the lungs.
However, there was no room for his wife Marcia to travel with him in the helicopter.
"I never have feared I was [at that point]"Fouraker told CNN." Roads were not open. "
Marshall came to his rescue and delivered Ms Fouraker to his husband's bed an hour later.
" I admire really the way he and so many other pilots really have stepped up to help people, "said Mrs Fouraker.
" Most people had a light look when they took a trip "Marshall reflected." I have many hugs the last few days! "
& # 39; I never have escorted hay & # 39;
Derek Jilek, from North Dakota, knew he wanted to help when he saw pictures of flooded farms across the Midwest.
He announced on Facebook to call his "farms and ranch neighbors" to donate a few hay bales to those who were hit by the floods.
The vast landscapes were destroyed by the flood water, and many farmers struggled to feed their livestock.
What started out as a little effort to collect donations became a nine truck convoy carrying thousands of dollars and equipment.
"I think that when you help or volunteer, I've always heard you do what you know. We know cows and we know trucking, so we did," Jilek told local news station WOWT.
The convoy received a police brief for part of the 600 mile (965 km) journey with a new police authority that took over as the lanes crossed the county borders.
Sgt Dan Kensinger from the Stark County Sheriff's Department said, "This was new to me. We've made funeral cages and various other things. I've never escorted hay."
