Why River Flooding Can Continue After Heavy Rain
River flooding does not always end when rainfall stops. Water from upstream portions of the watershed can continue moving downstream, while already-saturated soils and additional precipitation can prolong elevated river levels.
Because the Illinois River is a large waterway, changes in river stage can occur gradually. As a result, communities downstream can remain at risk even after local weather conditions improve.
What Residents Should Watch For
Residents and businesses near the Illinois River should continue monitoring official river forecasts and local flood information.
Floodwater can cover roads, agricultural areas and other normally accessible locations. Water levels can also change unexpectedly, particularly following additional rainfall upstream.
Flood Safety Reminders
- Never drive through a flooded roadway.
- Turn around and use an alternate route when water covers the road.
- Do not walk through moving floodwater.
- Keep children and pets away from swollen rivers and flooded areas.
- Follow barricades and road closures.
- Residents in low-lying areas should be prepared for additional rises.
- Continue monitoring updated National Weather Service forecasts.
The National Weather Service specifically urges people with interests along the affected rivers to remain aware of the latest forecasts and associated flood risk. (National Weather Service)

The Illinois River flood situation near Havana and Beardstown remains a concern across parts of central Illinois, although current forecasts indicate that river levels should gradually decline.
