<br />between Franktown and a point approximately 5 miles north of <br />enver, <br />at approximately 3 p.m. and continued until approx~mate.y p.m. <br />Cherry Creek crested at approximately 10 p.m. and had a peak <br />discharge of 25,000 cubic feet per second (cfs) in Denver. The <br />Cherry Creek Flood Commission estimated that runoff occurred from <br />an area of approximately 200 square miles. Flood damages in the <br />reach between Franktown and the site of the existing Cherry Creek <br />Dam and Reservoir totaled $554,000. <br /> <br />A large storm mass moved into southeastern Colorado on August 25, <br />1945, and extended over the Cherry Creek basin. Unofficial rain- <br />fall amounts varied from 2 to 5 inches. Severe flooding occurred <br />along Cherry Creek in the Franktown-Parker area. The gaging sta- <br />tion at Melvin recorded a peak discharge of 10,700 cfs. Total <br />damages were estimated at $200,000. <br /> <br />A severe storm centered over the Bayou Gulch basin, a tributary to <br />Cherry Creek, during the afternoon of July 28, 1922. Heavy rain- <br />fall was reported in the area bounded by lines 3 miles north of <br />Parker, approximately 4 miles west of Cherry Creek, 1 mile south <br />of Franktown, and by the Douglas County limits on the east. Unof- <br />ficial rainfall amounts varied from 1 to 3.5 inches and occurred <br />in approximately 2 hours. An estimated peak discharge of 8,700 <br />cfs flowed out of Bayou Gulch. The discharge on Cherry Creek, 3 <br />miles north of Parker, was estimated to be 17,000 cfs. Although <br />no damage occurred in Denver, this was considered a major flood <br />for the upstream part of the basin. <br /> <br />Peak discharges along Cherry Creek were 1,000 cfs upstream from <br />Franktown; 39,900 cfs near Melvin; and 58,000 cfs at Cherry Creek <br />dam. An estimated peak discharge of 14,100 cfs flowed from Piney <br />Creek, a right-bank tributary of Cherry Creek. During the evenin~ <br />and night of June 16, the Cherry Creek reservoir impounded a flood <br />that had a volume of 16,000 acre-feet. Three of the 18 small dams <br />constructed by the SCS-in -the - upper Cherry -Cl'eek basin between- <br />Franktown and Parker were filled. TWo of these were subsequently <br />overtopped and sustained erosion damage. The remaining structures <br />were outside the area of high-intensity rainfall and received only <br />moderate runoff. The heavy runoff caused major flooding along the <br />main stem of Cherry Creek from the vicinity of Franktown to the <br />Cherry Creek reservoir. Approximately 2,720 acres were flooded. <br />Most of the bridges across Cherry Creek were either damaged or <br />destroyed. One life was lost during the flood on Cherry Creek. <br />Flood damages totaled approximately $1.3 million. <br /> <br />NO floods 9f consequence have occurred since 1965. <br /> <br />6 <br />
