March 15, 2023

The snow-inducing technique called cloud-seeding has been around for more than 60 years. Although not a panacea for drought-stricken regions, cloud-seeding can increase seasonal precipitation by about 10%. In the Reno area alone, winter cloud-seeding efforts are estimated to add enough water to supply about 40,000 households for a year.
