The grimy water left a muddy trail around the sides of their home and a high-water mark several feet up the wall in the basement. Although floodwater didn't reach the second story, Nichols said the moisture did.
"I mean, the mold had mold," Nichols said. "I've never seen so many colors of mold."
The damage to the Nichols' house was mostly to the interior. Closer to the river, the wreckage was profound. At one house, a porch and assorted debris were wedged against a tree on top of a chain-link fence. Sand was pushed off the driveway and piled like snow along the edges. Open garage doors revealed walls blotted with mold.
