Portions of the Sangamon and Illinois rivers are currently under a flood warning due to ice jams that have caused flooding in some parts of west central Illinois.
The National Weather Service in Lincoln said that the Sangamon River at Oakford in Menard County and Chandlerville in Cass County and the Illinois River at Beardstown in Cass County and Havana in Mason County have seen at least minor flooding in some areas, with minor to moderate flooding in the forecast for the next several days.
In Oakford, NWS says that the observed stage Friday afternoon came in at 471.4 feet and will crest sometime early Sunday morning at 473 feet, causing flooding in low-lying agricultural areas. Chandlerville had an observed stage at 458.7 feet, with NWS forecasting that the stage will go up to 460 feet by Sunday morning.
Impacts along the Illinois River are expected to be delayed, with Beardstown expected to increase to 20.5 feet by next Friday, which could lead to seepage problems in the South Beardstown Drainage and Levee District. The observed stage at Havana is expected to increase to 19.5 feet on Friday, which would lead to the closure of an access road to the north campground at Anderson Lake.
