The Flooding Character of McLean County

River overflow along the Green, Ohio, and Mississippi rivers characterizes flood events in McLean County. Between January 31st and February 15th, 2025, heavy rainfall caused major flooding on the Green River, damaging numerous structures in Rumsey and lower Calhoun. Another prolonged event in February and early March 2025 saw continued moderate flooding on the Green River near Calhoun, with minor flooding affecting bottomland areas at multiple sites.

While flash flooding has also occurred, the data indicates a higher frequency of general flood events. NFIP claims show that properties in Zone A have experienced the most claims, with an average payout of $15,072 for 1.9 feet of water depth. Properties in Zone X, though fewer in number, have seen higher average payouts ($19,042) with an average water depth of 0.4 feet.

Homeowners in flood-prone areas, particularly those near rivers or in Zone A, should pay close attention to flood risk. Residents in Zone X and Zone Unknown also have a history of claims and should be aware of potential flood impacts.
