Heavy rains pound central Indiana

(CNN) - Heavy rains - as much as 11 inches in a few communities– flooded central Indiana on Saturday, testing levees and forcing many to find safety atop rooftops.

No injuries or fatalities were immediately reported, state officials said.

The worst-hit areas were communities about 25 miles south of Indianapolis and west in Terre Haute, with most towns receiving 6-10 inches of rainfall, said John Hendrickson, a meteorologist with the National Weather Service.

He said some affected areas hadn't seen a such flooding for 100 years.

Officials cast a wary eye at two levees in Johnson County, one of the hardest hit areas, as water spilled over them - but they still held up. A small community downstream from the levee at Princess Lake was trapped as roadways leading out remained submerged Saturday afternoon, Hendrickson said.

A hospital in Johnson County was also flooded.

Video from the scene showed people wading in waist-high water, trying to keep their belongings dry. Water inched over cars and rescue boats carried people to shelters.
