<br />Relatively minor flooding was reported on the South Platte River. <br />. Flood of 1942. The flood of April-May on the South <br />Platte River and tributary streams was the result of snowmelt <br />runoff being augmented by heavy precipitation during the last <br />half of Apri 1 and the first part of May. The mountain area above <br />Chatfield Dam produced most of the volume that passed the Denver <br />gage and, although peak values during this flood were not high in <br />comparison to other floods, the volume of runoff was excessive, <br />with a 30-day runoff of 265,000 acre-feet flowing past the Denver <br />gage and a 60-day runoff of 395,000 acre-feet. Four separate <br />flood crests occurred at the Denver gage with the maximum peak of <br />10,200 cubic feet per second recorded on 25 April. Peak flows in <br />excess of 8,500 cubic feet per second were, however, recorded on <br />19, 23 and 30 April. The minimum flow at Denver during the 24- <br />day period from 19 April to 13 May was about 4,500 cubic feet per <br />second. <br /> <br />Flood of 1948. Heavy rainfall over a large area east of <br />Denver caused flooding in late May and early June on the South <br />Platte River between Sand Creek and Fort Lupton. Several <br />approaches to county bridges were washed out as well as flooding <br />of some agricultural land. <br />Flood of 1949. Heavy rainfall over a melting snowpack <br />caused flooding on the South Platte River from mid-May to late <br />June from Littleton, Colorado to North Platte, Nebraska. <br /> <br />5 <br />
