Document Description
SMUD is proposing to expand its El Dorado Cloud Seeding Program, which would increase SMUD's current cloud seeding area from 190 square miles to approx 444 square miles of the Upper American River watershed, primarily in El Dorado County. The expanded target area would be treated with silver iodide nuclei dispersed by stationery ground-based units, aircraft, and mobile units transported to selected sites. The program is designed to produce localized increases in snowfall and subsequent snowmelt over a larger area of the watershed of SMUD's Upper American River Project. Like SMUD's current cloud seeding program, the proposed project would focus on the watersheds of Ice House, Union Valley, and Loon Lake reservoirs and their hydropower facilities in El Dorado County. The proposed project would also include the South Fork American River watershed that drains to Slab Creek Reservoir and its associated hydropower facilities.
