Derek Fimmen has been working to restore his mother's finished basement ever since the LaMoine River flooded it about a month ago. Fimmen said he and his family are working to prevent that from happening again.
"It's possible the river might come above the level of the basement doors, so we're planning on building a sand bag barricade tonight," he said.
If it does come in again, Fimmen says it'll undo hundreds of hours of hard work.
"We've put in so many hours to have more flood water come in and damage everything we've done would be a bit disheartening," said Fimmen.
McDonough County Emergency Management Director Dan Kreps said he doesn't think water levels will get as high as they were in April, but he's still concerned.
"With the ground already saturated with water, it's not going to be able to absorb any, so there probably would be some flash flooding if we get 5 inches overnight all at one time," Kreps said.
Fimmen said his mother spent thousands of dollars to get her basement cleaned, and he doesn't know what he'll do if it floods again.
"I can't imagine just completing it and starting it back over again. I mean if you have to you have to but hopefully we can avoid it."
Kreps said the public needs to be aware of more than just flash flooding. With severe weather and wet ground, power lines have a greater chance of being blown over and falling on the road.
