OPTIMIZING CLOUD SEEDING FOR WATER AND ENERGY IN CALIFORNIA
March 2007 | Arnold Schwarzenegger Governor |
“Cloud seeding has been conducted in California for over 55 years, one of the longest records of operational weather modification anywhere in the world. The earliest program was at the Bishop Creek watershed in the eastern Sierra in 1948, sponsored by the California Electric Power Company, now Southern California Edison (SCE) (Henderson 2004).
The Lake Almanor and Mokelumne projects of Pacific Gas and Electric (PG&E) (Marler 1992) and Upper San Joaquin project of SCE have both operated for over fifty years. The Santa Barbara operational precipitation enhancement project (Griffith et al. 2005) began in 1950, with some research phases between 1957–1960 and 1967–1974. Other programs have been operated in Los Angeles and Monterey counties.”
