A Flash Flood Warning issued by the National Weather Service remains in effect until 8:15 p.m. today in Miller County along the Osage River below Bagnell Dam.

Operators reported the floodgates at the dam were opened to 60,000 cubic feet per second at 10 a.m. This will cause flash flooding downstream of the dam.

Bagnell's discharge measurements had risen Tuesday from 32,785 cfs at 9 a.m. to 49,193 cfs at 9 p.m., according to Ameren Missouri.

A Flash Flood Warning means that flooding is imminent or occurring. If you are in the warned area move to higher ground immediately. Residents living along streams and creeks should take immediate precautions to protect life and property.

Meanwhile, a Flood Warning continues for the Osage River near Mari-Osa Campground, off U.S. 50, and at St. Thomas until further notice.

At 7:30 a.m. today, the stage at Mari-Osa was 28.0 feet. Flood stage is 19.0 feet. The river is forecast to rise to near 28.4 feet by late Thursday morning. However, rainfall heavier than forecast could cause river levels to rise even higher than predicted. (Use the links below for updated information.)

At St. Thomas, the Osage River was measured at around 20 feet at noon today, with the level expected to rise to 23.8 feet by Thursday noon.
