Moderate flooding continues along northern portions of the Illinois River but crests near where it intersects the Mississippi River could reach historic levels.

The National Weather Service reports the Illinois River measurement in Peoria this morning was 24.29 feet. The NWS classifies this as moderate flooding. Peoria’s flood stage is 18 feet. Major flooding levels are being reported from Havana southwest toward the Mississippi River.

The Illinois River at Valley City in Pike County is forecast to crest at 26-point-9 feet next week. The record there is 27 feet.

Predictions are that the Mississippi River will crest in Alton 38.5 feet by next week. That would be the second-highest crest in history.

High water along the Mississippi River has forced bridges to close between Illinois and Missouri, causing extensive detours for some motorists.
