On 16 July 1993, the Governor of Illinois ordered 270 members of the 126th Air Refueling Wing to State Active Duty to support the Illinois National Guard's flood control mission during the Great Flood of 1993. Members patrolled levees, sandbagged boils and provided security on a 24 hours basis. Many guardsmen aided in evacuation of residents. Medical personnel aided thousands. The unit had members in Alton, Anna, Carrollton, Carbondale, Cahokia, East St. Louis, East Carondelet, Edwardsville, Evansville, Grafton, Granite City, Hartford, Jerseyville, Murphysboro, Prairie du Rocher, Quincy, Springfield, and Winchester. By the time the crisis was under control in the early fall, over 700 personnel from the 126th Air Refueling Wing and assigned units had pulled duty in the flood ravaged towns.
