Flooding in Indiana, April 17 to 30, 1999

5 different rain events caused prolonged flooding and multiple crests along the Wabash River from Lafayette to across the border from Riverton, Illinois. The first event occurred on the 15th and 16th as 2 to 3 inches of rain fell over a uniform area. Lafayette crested at 15.76 feet (flood stage is 11 feet) on the 18th, Covington crested at 19.88 feet (flood stage is 16 feet) on the 19th, Montezuma crested at 19.60 feet (flood stage is 14 feet) on the19th, Terre Haute crested at 17.63 feet (flood stage is 14 feet) on the 21st, Hutsonville crested at 19.90 feet (flood stage is 16 feet) on the 23rd and finally Riverton crested at 17.96 feet (flood stage is 15 feet) on the 24th. On the 20th and 21st, 1 to 2 inches of rain fell across much of central Indiana. This rain helped prolong the the lowland flooding along the Wabash. The third event occurred on the late evening of the 22nd and early on the 23rd. 2 to 4 inches of rain fell across northern Indiana which caused another crest to form in west central Indiana and move down the Wabash River. Lafayette crested at 15.08 feet on the 24th, Covington crested at 18.41 feet on the 26th, Montezuma crested at 16.34 feet on the 26th, Terre Haute crested at 14.78 feet on the 27th and finally Riverton crested at 16.82 feet on the 28th. The final rain event came on the 27th and 28th and produced 1 to 2 inches of rain across much of the state. This final rain event allowed Lafayette to crest at 13.02 feet on the 29th, Covington to crest at 17.51 feet on the 30th and Montezuma to crest at 15.59 feet on the 30th. All in all, the flooding lasted around two weeks and did little agricultural damage.
