<br />during the night of July 11-12, 1935 and is described in USGS Water- <br />Supply Paper No. 997, pages 111-112. This storm was described as a <br />cloudburst type which produced rainfall amounts in excess of 8 inches <br />over an area of about 20 to 25 square miles. The most intense portion <br />of this rainfall occurred in a period varying from 1/2 hour to It hours. <br />The peak discharge resulting from this storm was estimated as 14,000 <br />cubic feet per second. The most intense and most damaging flood in <br />recent years was produced ~ the storm which occurred during the night <br />of May 14-15, 1951. Intense rainfall from 4 to 7 inches with 10calJ,y <br />severe hail and wind occurred generally over the area of Wolf Creek and <br />the surrounding area. The peak discharge resulting from this storm <br />was estimated as 22,000 cubic feet per second ~ the Corps of Engineers. <br />Intense rainfall of June 3, 4, 5, 1949 produced 'flooding on Wolf Creek <br />in excess of 10,000 cubic feet per second. The maximum 24-hour precip- <br />itation on June 4, 1949 waS 4.45 inches at Granada of which 1.27 inches <br />occurred in one hour and 1.81 inches in two hours. <br />4. The preliminary standard project flood peak discharge and <br />volume for ,Wolf Creek was estimated as 64,000 cubic feet per second <br />and 26,600 acre-feet, respectiveJ,y. These values were estimated from <br />relationships of the maximum experienced flood peaks and volumes and <br />the standard project flood peaks and volumes computed for other drain- <br />age areas in the Arkansas River Basin in Colorado which were assumed <br />to have similar characteristics. These relationships are shown <br />graphicalJ,y on plate 2. <br />5. A preliminary discharge-frequency curve was developed for <br />Wolf Creek ~ using the discharge-frequency computed for Dry Creek at <br /> <br /> <br /> <br />. <br /> <br />. <br /> <br />2 <br /> <br />_ ~ __ __~L .,__~ <br />
