. c. East of metropolitan Denver, the storm pattern extended over. Kiowa, COIIlIIl&Ilche, Bijou, Beaver, and Badger Creeks. The storm which occurred over Bijou Creek and adjacent watersheds centered principally over the upper Bijou Creek basin. The resultant flooding exceeded all previous records in area flooded, peak discharges, and flood damages. Interstate highway and other major highway bridges were destroyed. The business sections of the towns of Byers and Deer Trail were almost completely destra.yed. The peak discharge of the Bijou Creek flood, estimated at an unprecedented 466,000 cubic feet per second, entered the South Platte River just above Fort Morgan,. Colorado, and caused extensive flooding and damage as far as the junction with the Platte River some 190 miles downstream. Overall, the floods during the period 14 June through 22 June, inundated an estimated 252,925 acres along 1.200 stream miles under flood. The basin streams in flood, and a schematic diagram of peak discharges, are illustrated on plates 5 and 6, respectively. General flood outlines of the South Platte River and its tributaries, and high water marks for the metropolitan reaches on the South Platte River and Sand and Toll Gate Creeks are included in the appendix to this report. Photos of selected flood scenes also are included in the appendix. d. Thirteen lives were lost in the South Platte River basin, including four on Plum.Creek, three on the Cache LaPoudre River, two on Bijou Creek, two on Beaver Creek, and one each on Cherry Creek and the Big Thompson River. 21 . FLOOD DAMAGES PREVENTED a. General. Federal flood control improvements located in the South Platte River basin in the areas of the June 1965 flood runoff include the Corps of Engineers' Cherry Creek Dam on Cherry Creek and the Soil Conservation Service's watershed projects in the upper Cherry Creek basin and the Kiowa Creek basin. b. Cherry Creek Dam and Reservoir. (1) During the evening and night of 16 June 1965, the Cherry Creek Reservoir impounded a flood which had a peak inflow of 58,000 cubic feet per second and a volume of 16,000 acre-feet. The peak discharge entered the reservoir at 7:30 p.m. on 16 June. Had the dam not been constructed, this discharge would have continued downstream, overflowing approximately 12 miles of Cherry Creek channel through a heavily developed area of Denver. Moreover, this flood would have joined the flood on the South Platte River which had originated on Plum Creek, and would have raised flood stages upstreem and downstream of the confluence of Cherry Creek. The flood originating on Plum Creek caused a peak discharge in the South Platte River at the Denver gage of 40,300 cubic feet per second. The combination of this 12 .
