Scott Sundberg knew parts of Iowa were literally underwater.

He knew things were bad.

But he didn't know how bad until he viewed the devastation from a small plane last week.

"We expected there would be some flooding ... but you would just see water, virtually as far as they eye could see," Sundberg said.

Sundberg works with the Mennonite Disaster Service in Akron, Lancaster County.  He visited eastern Iowa to assess the damages.

"I can't imagine what it would be like to know your house is underwater by feet or yards," Sundberg said.  "And what it would look like afterwards.  Think about dry wall that's been soaking for days - Iowa has never experienced anything like this."

Sundberg said many residents are calling the flood the "Katrina of Iowa."  It's also being dubbed the worst disaster Iowa has ever encountered.

So far, MDS officials have collected $10,000 for flood victims.  But with billions in damages, more money will definitely be needed.

Volunteers will also be needed eventually to help clean up the mess.  MDS helps under-insured, uninsured, elderly, and disabled people rebound after a disaster.

Volunteers are asked to wait because there are so few hotel rooms available in Iowa.

Sundberg said he hopes people decide to trade their summer vacations in August and September for a trip to the midwest.  He said the help will still be needed, and the mess will still be there.
