38 An unbelievable flood. Water 4 feet above May 2011 flood. Levee at Mt. Carmel overtopped. Great flood destruction in both Indiana and Illinois affecting major power plant, residential and business areas. Indiana State Road 64 and nearby railroad flooded. Possible flooding to I-64.
35 Flood waters threaten Gibson Generating Station located in Gibson County Indiana just across the river from Mt. Carmel. In June was the third largest power plant in the nation according to the Indianapolis Star. Its generated power went to 79 Indiana counties including the Indianapolis Area. Wabash River is at a record level...about one foot above the January 2005 flood and the local levees in the East Mount Carmel...Indiana area. Levee Unit #5 overtopped. A serious flood is in progress.

This includes the northern outskirts of Mount Carmel, Illinois, western Gibson County Indiana and eastern Wabash County Illinois. Extensive flood damage in unprotected flood areas. A flood with the flow of March 1913 would reach an estimated 36 feet and cause failure of agricultural levees and widespread rural flood destruction.

High water backs up into Bon Pas Creek. Browns, Illinois may be surrounded by water if heavy local rain occurs. River is 3 miles wide at I-64.
28.5 Extensive flooding in progress. Some residents along South Division Street in the Mt. Carmel area and in the Keensburg area must relocate.

28 Critical Stage of Rochester-Mcleary Bluff Levee. Cattle and farm equipment must be moved. Most roads along river or near river are now impassible. Agricultural losses 100 percent in areas that are not protected by levees. The Wabash River is more than 2 miles wide at I-64.
27.5 In the City of Mt. Carmel, all local roads flooded east of the levee except for South Division.

Three Illinois township roads south of Illinois 1 between Keensburg and Grayville are flooded for a total of 10 miles. Access to oil fields in the Keensburg and Grayville are blocked by high water.
26 Relocation to higher ground of cattle and some farm equipment is necessary. Agricultural losses are near 100 percent in areas that are not protected by levees. Extensive lowland flooding in western Gibson County Indiana.
25.5 Extensive lowland flooding in progress. Much of the flood plain activity is affected by high water. Numerous local river roads flood.
24 Extensive lowland flooding in progress. Some mobile homes must be moved if water rises higher. Installation of flood gate A at Mount Carmel is necessary. Access to local camp sites are blocked, but minimal impact to commercial activities because of gate closure. In Wabash County Illinois, CR 1280 E and South Division Street are flooded.
23.9 Extensive lowland flooding in progress. In Wabash County Illinois, South Division Street and 1.5 miles of CR 1280 E remain flooded. High water blocks access to cabins along South Division Street and some nearby oil fields.
