have approximated the area covered by the 1965 flood. It is evident, <br />therefore, that the Mt. Carbon project would serve as a major unit in <br />our plan to provide the desired degree of flood control for the Denver <br />metropolitan area. <br />VU -GRAPH - MT. CARBON PLAN <br />Physically, -the Mt. Carbon project would be similar to the Cherry <br />Creek and Chatfield projects. The earthfill dam, shown here in the <br />center of slide, would be 162 feet high and 4,400 feet long. There <br />would also be a supplementary embankment located to the south of the <br />main embankment which would be 50 feet high and 2,700 feet long. The <br />reservoir would provide storage capacity of 74,750 acre -feet, including <br />2,400 acre -feet for conservation, 26,000 acre -feet for flood control, <br />and 464300 acre -feet for surcharge storage. <br />Located at the upstream end of the reservoir are the Soda Lakes <br />which offer a potential for recreational development in connection <br />with the Mt.. Carbon:.plan.. Our report is presently being processed to <br />Congress for consideration. <br />VU-GRAPH - SOUTH PLATTE RIVER BASIN <br />PRELIMINARY FLOOD CONTROL PLANNING <br />The scope of our over -all study of the water resource problems of <br />the South Platte River basin is depicted by this slide. Here- we show the <br />river winding from its source southwest of Denver to a point several <br />miles downstream from Sterling, Colorado. In addition to the three <br />dams and reservoirs already discussed, we have looked at, or are con- <br />sidering several smaller dams in the Sand Creek basin just east of <br />Denver (West Tollgate, East Tollgate, and Sand Creek dam sites).
