Heavy rain on February 28th sent the mainstem rivers above flood stage early in March. Minor to moderate flooding occurred on the Ohio, Wabash, and Little Wabash Rivers. Near to above normal precipitation in March kept some locations above flood stage through the entire month. The generally 1 to 2 inches of rain that fell on the 11th caused the river falls to come to an end, and even caused some renewed flooding. Another wet period occurred from the 15th to the 18th with several days of precipitation across the area. This multi-day event led to a renewed period of flooding for much of the Ohio and Wabash basins. Another round of storms passed through on the evening of the 27th with heavy rain continuing through the overnight hours. This more widespread rain caused more significant rises on area rivers and streams.
