A cloud seeding pilot program that aimed to enhance water supplies within the Santa Ana Watershed has been called off, due to insignificant results and the proliferation of burn scars from wildfires in the target areas, including Orange County. Officials with the Santa Ana Watershed Project Authority announced earlier this month that the four-year program, which began in late 2023, would not be continued as researchers did not see the anticipated results. … Findings from a validation report published in May indicate while precipitation levels in the San Bernardino and San Jacinto mountains, in the respective northeast and southeast corners of the territory, increased by 4%, additional rainfall in the San Gabriel and Santa Ana mountains was negligible.
