Illinois River Flooding Continues in Central Illinois
A Flood Warning remains in effect for portions of the Illinois River near Havana and at Beardstown, where river levels continue to run above the established flood stage. The latest National Weather Service information indicates that the flooding is classified as minor, but residents, agricultural interests, boaters, and others along the river should continue monitoring conditions.
The flooding is occurring as elevated river levels slowly work their way downstream. While the overall trend is toward lower water levels, the river remains above flood stage at both monitoring locations.
Illinois River Near Havana
The Illinois River near Havana remains under a Flood Warning affecting Mason County, Cass County, and Fulton County.
As of the latest Thursday morning observation, the river stood at 14.8 feet, above the 14.0-foot flood stage. The river had reached a recent 24-hour maximum of 15.2 feet.
Forecasts indicate that the river should continue falling and is expected to drop below flood stage early Saturday afternoon.
What Flooding Means Around Havana
At the 14-foot flood stage, minor flooding begins in agricultural areas that are not protected by levees. Consequently, low-lying farmland and areas immediately adjacent to the river can remain vulnerable even as the river begins to recede.
Residents should avoid assuming that falling water levels mean the area is immediately safe. Floodwater can remain in low-lying locations, drainage areas, and roads after the river gauge begins showing improvement.
Illinois River at Beardstown
A separate Flood Warning continues for the Illinois River at Beardstown, affecting Morgan County, Cass County, Schuyler County, and Brown County.
The latest observation placed the river at 15.4 feet, compared with a flood stage of 14.0 feet. The river had reached a maximum stage of 15.8 feet during the preceding 24-hour period.
The forecast calls for a gradual decline, with the river expected to fall below flood stage Sunday evening.
Beardstown Flooding Impacts
Although the current flooding is considered minor, continued high water can affect low-lying areas, agricultural land, drainage systems, river access points, and locations near the river.
At higher stages, additional problems can develop in areas protected by levees and drainage infrastructure. Therefore, residents with property or interests along the river should continue following official river forecasts until the warning is canceled.
Why River Flooding Can Continue After Rain Ends
River flooding does not necessarily end when rainfall stops.
Instead, water from upstream portions of the watershed can continue moving downstream. Saturated soils also have less capacity to absorb additional water, allowing more runoff to reach rivers and tributaries.
As a result, river levels can remain elevated—or even rise—after the weather has already improved.
For Havana and Beardstown, the latest forecasts suggest the Illinois River is now trending downward. However, the river remains above flood stage, meaning flood-sensitive locations can continue experiencing impacts.
Safety Tips During Illinois River Flooding
If you live, work, or travel near the Illinois River:
- Stay away from flooded roads and low-water crossings.
- Never drive around barricades or through water covering a roadway.
- Keep children and pets away from swift-moving or contaminated floodwater.
- Monitor updated river forecasts and Flood Warning information.
- Move equipment, vehicles, and other vulnerable property away from low-lying areas when possible.
- Boaters should use extra caution because strong currents, debris, and changing water conditions can create dangerous conditions.
- Follow instructions from local emergency management officials.
Turn Around, Don’t Drown
Even relatively shallow moving water can sweep a vehicle off the road. If water covers a roadway, turn around and find another route.
Flood Outlook for Havana and Beardstown
The encouraging trend is that both river locations are forecast to continue falling.
The latest forecast has the Havana gauge falling below flood stage Saturday, while Beardstown is expected to remain above flood stage somewhat longer, dropping below flood stage Sunday evening.
Nevertheless, conditions can change if additional heavy rainfall occurs upstream. Residents should continue checking updated forecasts rather than relying solely on the current projected river decline.
Radar Watch HQ Final Thoughts
The Illinois River flooding near Havana and Beardstown is currently a minor flooding situation, but elevated river levels can still create dangerous conditions in low-lying areas.
The overall forecast is favorable, with both gauges expected to gradually fall below flood stage. Until that happens, however, residents and travelers near the river should remain alert, avoid flooded areas, and continue monitoring official updates.
