Cloud seeding in the Eastern Box Elder/Cache County area has been ongoing for 16 years beginning in 1989. There were 23 cloud seeding generators in the project area for the 2003-2004 winter season. Target and control regression analyses show an average increase in precipitation of 16% and an average increase in April I S\ snow water content of 10%. The West Box Elder project area has been operating for 12 years now. Cloud seeding began in 1989 but was suspended during 1998, 1999,2002 and 2003. The project area has 10 cloud seeding generators. The target area has no precipitation gages but it does have two snow courses. A target and control regression analysis shows an average increase in Aprillsl snow water content of 18%. Cloud seeding began in Tooele County in 1976 and continued through 1982. Seeding resumed in 1989 through 1992 and again in 1996. The project area has becn seeded a total of20 seasons. The project area has eight cloud seeding generators. Target and control regression analyses show an average increase in precipitation of 20% and an average increase in Aprills' snow water content of 18%. The primary target area of the Ccntral/Southern Utah project has had 27 seeded scasons. It has operated continuously since the water year 1974. with exception of the period from 1984-1987. There \vere 62 cloud seeding generators in the project area for the 2003-2004 winter season. Target and control regression analyses show an average increase in precipitation of 15% and an average increase in April 1 ~I snow water content of4%. Ten winter seasons of cloud seeding have now been conducted in the Western Uinta Mountains. There arc 14 cloud seeding generators in the project area. Target and control regression analyses show an average increase in precipitation of 1.3% and an average increase in April I S1 snow water content of 2.3%. 5
