To meet that <br /> <br /> <br />part of Denver's requirements not available from stream runoff, <br /> <br /> <br />storage releases from upstream reservoirs must be made. RlUloff data <br /> <br /> <br />above major points of diversions are shown below: <br /> <br />The two major sources of water for the metropolitan area, the South <br /> <br /> <br />Platte River and Clear Creek, have an average annual flow at the gaging <br /> <br /> <br />stations indicated above of approximately 420,000 acre-feet per year. <br /> <br /> <br />Cherry Creek stream-flow, averaging about 6,900 acre-feet per year, is <br /> <br /> <br />quite erratic as a large part of this discharge is from floods occurring <br /> <br /> <br />at infrequent intervals. The necessity of developing municipal water <br /> <br /> <br />supplies in an orderly manner and of providing storage to accommodate the <br /> <br /> <br />great variability in surface TIUloff is apparent. <br /> <br />14 <br />
