The rigors of seeding by 24-hour experimental <br />periods on a randomized basis impose problems not found in a strictly <br />operational program where activities can be altered as the cloud <br />conditions change. <br /> <br />The CRBPP provided information that will improve future project <br />designs. If careful attention is paid to these findings, future <br />winter orographic seeding programs will provide more technological <br />information on precipitation enhancement as well as increasing water <br />supply. The CRBPP analysis has led to identification of seedable <br />situations with much more certainty than before, and highlighted the <br />need for more detailed diffusion information, the importance of <br />shorter forecast periods, and accurate description of current weather <br />conditions for operational use. <br /> <br />CRBPP results point to an overall potential for seeding-produced <br />increases in precipitation of about 10 percent during a winter of <br />average snowfall. The resulting potential increase in streamflow is <br />19 percent or 197 x 106 m3 for the San Juan River. <br /> <br />11-3 <br />
