Heavy rains in early June 2008 soaked the U.S. Midwest, leaving swollen rivers in their wake. By June 8, 2008, the National Weather Service had issued flood warnings for numerous counties throughout Indiana and Illinois. The lower Wabash, White, and East Fork White watersheds had all been affected by the deluge, according to National Weather Service bulletins, and streamflow gauges on parts of the White and East Fork White River recorded 100-year-flood levels, according to preliminary reports from the U.S. Geological Survey.
