OMAHA, Neb. — The Little Blue River has left its banks in south-central Nebraska, raising concerns about damage to county bridges.

The National Weather Service said Tuesday that the river was a foot above flood stage at 10 feet and cresting near Deweese. The high water was moving downstream to Nuckolls and Thayer counties, where minor flooding is expected through Wednesday. Stream flooding also is expected to continue in Adams and Webster counties.

The service issued a flood warning for parts of Nuckolls and Thayer counties. A flash flood watch was issued for southeast Nebraska and southwest Iowa.

Heavy rains Sunday night and Monday morning saturated the ground in parts of the Nebraska counties. The service said more than 7.25 inches of rainfall was recorded in just four hours early Monday at a reporting station two miles northeast of Blue Hill in Webster County. About four miles southeast of Roseland in Adams County, 5.6 inches was recorded.

The Adams County highway superintendent, Dawn Miller, said there wasn’t much rain Monday night, but some rural county roads remained covered with water.

“Our river bridges are what we worry about,” Miller said, referring to spans over the Little Blue River. “We have bridges that are still closed until we can get underneath and they can be inspected.”

In Iowa, Fremont County emergency manager Mike Crecelius said the county didn’t have any river flooding to contend with, despite the heavy rain overnight.

“We got drowned pretty good here in Fremont County,” he said Tuesday, citing a rainfall report of 2.51 inches in Shenandoah.
