The County of San Luis Obispo Flood Control and Water Conservation District (District) is proposing a Winter Cloud Seeding Program for Lopez Lake (project). The project objective is to increase precipitation in the Lopez Lake watershed during winter precipitation events. The seeding program would use a combination of approximately eight ground-seeding sites and aircraft.
Environmental Document Approved
On August 13, 2019, A public hearing was held and The Board of Supervisors approved a Final Mitigated Negative Declaration (MND) for the Winter Cloud Seeding Program for the Lopez Lake and Salinas Reservoir Watersheds. At the same meeting implementation of a Winter Cloud Seeding Program for Lopez Reservoir in 19/20 was approved. A program for the Salinas Reservoir was not supported at this time.
Lopez Watershed Cloudseeding Program Initiated
On December 17, 2019, the Board of Supervisors approved a contract with North American Weather Modification, Inc. to implement a cloudseeding program for the Lopez Reservoir Watershed to begin January 2020 thru April 15, 2020 with the option for two additional seasons. The first season will be aircraft only. Subsequent seasons would likely utilize a combination of a land seeding site and aircraft.
