History of Operation

Cloud seeding has been conducted in the Tahoe and Ruby Mountain areas since the 1960's. The DRI has designed and operated the program since its inception. The original seeding equipment was acquired mainly through U.S. Bureau of Reclamation (USBR) grants to DRI (e.g., Pyramid Lake Project). The Ruby Mountain operational project started in 1981 using surplus USBR generators. State funding for the program began as early as 1979-80, and State funding continued through 2009. The Walker River Irrigation District (WRID) has funded additional equipment for the program in the Walker Basin.

In 2007 the DRI added equipment to programs in Colorado to enhance seeding activity in the Upper Colorado River Basin. These additions were funded by Lower Basin agencies including the Southern Nevada Water Authority.
