52 Significant and widespread flooding occurs. Major inundation occurs in Fairborn, Riverside and portions of Wright-Patterson Air Force Base. Much of Dayton itself along the Mad River is protected by levees to 58 feet.
40 This exceeds the flood of 1959 by eight feet. In addition to road and runway flooding at Wright-Patterson Air Force Base, flooding occurs along Route 4 in numerous locations from near Huffman Metropark and northward. Flooding also occurs near Osborn Road.
