North American Weather Consultants is the cloud seeding contractor for the first four project areas. The total estimated cost for these projects is $415,000, of which the state will cost share $207,500 (50 percent).

The Central/Southern Utah Project has operated continuously since water year 1974, with the exception of the extreme wet period from 1984-87. The project has 30 seeded seasons. The project area has 68 cloud seeding generators. Using a target and control regression analysis for December through March precipitation, the Central/Southern Utah Project Area indicates a 14 percent average increase in precipitation for this period. Seeding began in the Tooele County Project area in 1976 and continued through the 1982 water year. Seeding resumed in 1989 through 1992 and again in 1996 to 2006. There are 23 seeded seasons. The project area has nine cloud seeding generators. Target and control regression analysis show a December-March precipitation average increase of 21 percent.The East Box Elder/Cache County Project Area has operated 19 years beginning in 1989. The project area had 23 cloud seeding generators from 1989-2001. Bear River Water Conservancy District (Box Elder County) did not participated in the project for the 2002 and 2003 seasons, limiting the project to 15 cloud seeding generators during this period.  The project was back in full operation for the 2004 to 2007 seasons and will continue this year.  Target and control regression analysis shows a December-February precipitation average increase of 18 percent. The West Box Elder Project Area has operated fifteen years.  It was operated from 1989 through 1997, and 2000 through 2001. The project was not operated in 2002 and 2003 seasons.  The project was operated during the 2004 to 2007 seasons and will continue this year.   The project area has 10 cloud seeding generators. The target area has no precipitation gages; however, there are two snow courses. A target and control regression analysis shows an April 1 snow water content average increase of 14 percent. The West Uintas Project Area operated for nine years from 1989 through 1993, plus 1995, and 2001 through 2007. It will be operated again this year with only the Weber River portion.  The Provo River Water Users Association chose not to participate this year.  The project area has 14 cloud seeding generators.  Target and control regression analysis show a December-March precipitation average increase of five percent. The Uinta Mountains Project Area operated for the years from 1975-1987.  It was operated again for the years 2003 to 2007.  It will be operated again this year.  The project area has 24 cloud seeding generators.  Target and control regression analysis showed a December-April precipitation increase of three per cent.
