INTRODUCTION <br />Bill Owens <br />Govemor <br />Greg E. Walcher <br />Executive D'uector <br />Dan McAuliffe <br />Acting Director <br />66-6o-?5- ?a _ <br />Colorado is pleased to provide the following information in support of the Reservoir Coordinating Committee <br />(RCC) for the three state Platte River Cooperative Agreement. In preparing the information we focused our <br />efforts on the South Platte River and select data which we believe is the most relevant for the RCC. We have <br />also included a number of Internet Sites which people can access for additional information and up-to-date <br />information over the next several months. <br />II. WATER SUPPLY OUTLOOK <br />Stream Flow <br />Attached are several graphs of historic and current (September 2001) flow information for the South Platte <br />River at Julesburg. The mean daily flow for the South Platte at Julesburg for September 2001 and for the period <br />of record (1902-present) is 147 cubic feet per second (cfs) and 255 cfs, respectively (see Figure 1). For <br />comparison the September 2000 mean daily flow at Julesburg was 74 cfs. <br />Figures 2 shows South Platte mean monthly flows at Julesburg. The reader can see that 2001 was a below <br />average water year. The overall flow was below average and the peak flow was earlier than normal and below <br />average. The affect of two below average years is also reflected by the dip in flows in March (reservoirs <br />topping of fl. <br />Estimated stream flow for the South Platte basin will be available in January 2001 and will be provided at our <br />next meeting.
