The annual runoff for the Northern Utah project areas is 481 ,800 acre-feet. <br />The annual runoff for the Central and Southern Utah project areas is 1,435,200 acre-feet. <br />The total annual runoff for both projects is 1,917,000 acre-feet. <br /> <br />Precipitation Increase from Cloud Seeding <br /> <br />Most of the cloud seeding activity in the Utah project areas occurs during the <br />December-March period. Target and control analyses, using precipitaton gages in the <br />cloud seeding project areas (target areas) and control precipitation gages in upwind <br />unseeded areas located in Idaho, Nevada and Arizona. have been made and published <br />(see References) by North American Weather Consultants. The data and analyses have <br />been reviewed and confirmed by the Division of Water Resources. In addition. target and <br /> <br />-4- <br />
