Cloud seeding may be part of the Metropolitan Water District of Salt Lake's operating plan for the coming year, with the hope of increasing water supplies 5 to 10 percent.

Salt Lake City undertook a two-month, $40,000 cloud-seeding program last winter and tentative results show cloud seeding increased precipitation 6 percent, said Don Griffith, North American Weather Consultants vice president.LeRoy W. Hooton Jr., Salt Lake public utilities director, said the $40,000 the city spent on cloud seeding gave the waning water supply a boost that was much cheaper and easier to implement than other options such as drilling a new well, which would have cost $250,000. "It was well worth the effort for what we got back in water sales," Hooton said.
