Floods in Indiana, June-August 1979

This report documents rainstorms and resultant floods in central and southern Indiana during the summer of 1979. Major flooding was caused by three storms, one in June and two in July 1979, centered primarily in central and southern Indiana. Peak discharge exceeded the 100-year recurrence interval at 16 sites in this area. State Civil Defense officials estimated that almost 50-million dollars damage was attributable to the July floods. Hydrologic data have been tabulated for streamflow sites in the areas of flooding. Reservoir storage volumes, observation-well data, rainfall totals, and discharge hydrographs are presented to show the intensity and time of the storms and resultant floods. (USGS)
