Storms dumped as much as 10 inches of rain on already-soggy central Indiana on Saturday, threatening dams, inundating highways and forcing the Coast Guard to rescue residents from swamped homes.
Flooding was also a problem in Wisconsin after storms blew through with tornadoes that injured at least five people.
Indiana Gov. Mitch Daniels declared an emergency in 10 counties as the Coast Guard was called in from the Great Lakes to help with flooding that has forced hundreds of people from their homes. No injuries or deaths had been reported.

Indiana state police reported evacuations in the Lake Lemon area about 10 miles northeast of Bloomington. Dams near Gold Point were close to collapse, police said.
