At least four people have been killed by the devastating Nebraska floods that have cut off access to several towns and ruined 500 homes in one county alone.
Two other men are still missing and presumed dead in Nebraska.
Rainfall and swollen rivers, left in the wake of the 'bomb cyclone' winter storm swirling through the US, has left Nebraska inundated with water, neighborhoods completely submerged, and bridges ripped apart.
Governor Pete Ricketts declared a state of emergency in 53 counties, saying that one-third of the state has been affected in the devastating floods and 2,600 locals living near rivers were urged to evacuate on Friday.
'This is the largest widespread amount of flooding we've had in the last half century,' Ricketts said on the deluge.
Some small towns and communities have been cut off by floods while others have seen fresh drinking water become scarce.
The flooding, which is the worst the state has seen in 50 years, has badly damaged up to 500 houses in Sarpy County.
Greg London of the Sarpy County Sheriff's Office said Sunday that one levee broke Thursday along the Platte River, and another broke Saturday.

Another 100 or so homes are damaged elsewhere in the county.

Nebraska saw its various rivers break through their banks, cresting at up to 25 feet and rushing into neighborhoods, forcing locals to climb on their roofs and cry for help.
The floodwaters from the Niobrara River in the northern part of the state were so strong they blasted through the 90-year-old Spencer Dam dam on Thursday, drowning the nearby town of Lincoln in water and completely washing out a bridge on US Highway 281.
The Missouri River, which borders Missouri and Nebraska reached 26 feet on Saturday - a foot below what's considered major flooding - but is expected to crest on Wednesday or Thursday at 29.3 feet, according to WPTV.
Crest records were set along the Platte and Elkhorn rivers. The Elkhorn reached 24.6 feet on Saturday in Waterloo, breaking the 1962 record by 5 1/2 feet.
