Abstract:

The snowpack enhancement cloudseeding program in Utah was operated continuously for ten consecutive years prior to the 1983-84 water year. It was designed to augment water supplies in areas which normally have large water deficits. The program is producing cost beneficial results by increasing wintertime precipitation with an average of 12% annually. The evaluation of the Utah program is basically accomplished through a statistical target-control correlation method. A conservative economic evaluation of this magnitude of increase indicates that water is being developed through the program at roughly one dollar per acre-foot.
