Correctionville, Iowa, totaled the most in Siouxland, at 6.47 inches in 48 hours.

While Brown said most roads were open or expected to be open by Sunday evening, he said farm fields reflected rain-related damage the most.

"We could see significant crop loss from standing water," he said.

Marian Gallagher, who owns farmland near Holly Springs, said she was unsure of the extent of the damage, but said she knew the torrential rain and a nearly full west fork of the Little Sioux River could make a significant impact.

"The fields I drove past are flooded; it's devastating," she said. "I can look out my front door and see water in the fields."

Amy Sulsberger, who owns farmland near Hornick, Iowa, said about half of her 800 acres were left underwater after the rain finally subsided. She said she is not sure what the next step will be as she waits for her waterlogged land to dry out.

"We don't know the damage until the water goes down," Sulsberger said. "We have to wait until crop adjusters can get out there, or we could replant. But we need it to dry out to replant."

Brown said a damage estimate may not be available until landowners have had their insurance companies inspect property.
