Cloud seeding has been conducted for water years 1990-91 and 1991-92 in Monterey County, California in response to the extended drought. The Monterey County Water Resources Agency weather modification program included both airborne and ground based cloud seeding operations and was designed to increase rainfall and subsequent runoff in the watershed drainages of Arroyo Seco River, and San Antonio and Nacimiento reservoirs. This paper describes the seeding methods, results, and program cost.
