Document Description
The proposed project is a Winter Cloud Program for Lopez Lake and the Salinas Reservoir. The project objective is to increase precipitation in the Lopez Lake and Salinas Reservoir watersheds during winter precipitation events. The seeding program would use a combination of approx 8 ground seeding sites and aircraft. It has been estimated that precipitation increases would be between 9% and 17% in the reservoir watersheds. The ground seeding sites are located in the inland portions of the San Luis Obispo and South County planning areas. The reservoir watersheds are located primarily in the North County and South County Planning areas and supervisorial districts 3, 4, and 5.
