ReseYVOir Storne <br />A summary of the status of select reservoir storage and reservoir capacity is provided in Figure 1. Generally, the <br />storage contents of these major South Platte reservoirs are below average and we anticipate that diversions to <br />storage will continue as long as weather conditions allow. Figure 4 shows reservoir storage for Colorado with <br />the South Platte basin estimated to be below normal storage patterns at 79 percent of average. <br />Snow Pack <br />State wide snow pack for Colorado was last reported for June 2000 and reporting will begin again-next month. <br />Figure 5 shows the snowpack for June 2000. The reader can see that the Colorado snowpack was much below <br />average (14%) for June, and South Platte flows, as shown in Figures 2 and 3, reflected this lack of snow and <br />corresponding runoff. <br />The Surface Water Supply Index (SWSI) is an indicator of mountain-based water supply conditions developed <br />by the Natural Resource Conservation Office and the Colorado State Engineers Office. The SWSI is based on <br />snow pack, reservoir storage, and precipitation for November through April. During the winter, snow pack is <br />given the most emphasis, except on the South Platte where reservoir storage is given the most weight. During <br />the summer actual stream flow conditions begins to replace snow pack. <br />The SWSI for Colorado as of September 1, 2000 is shown in Figure 6. The SWSI for the South Platte basin is <br />1.9, indicating a near normal surface water supply. <br />III. SUNIMARY <br />As of September 2000 we are expecting average conditions in the South Platte basin. However, with last springs <br />less than normal snowpack, and with the anticipated diversion to storage, flows at Julesburg will likely be below <br />average. <br />2
