Document Description
Placer County Water Agency Middle Fork American River Weather Modification Project would include the seasonal implementation of an aerial cloud seeding program for the upper middle fork American River watershed using aircraft equipped with focused silver iodide dispersal technology. The project would not result in any ground disturbing activities and is strictly designed to augment the natural rate of snowfall that occurs in orographic clouds as they develop and progress over the headwaters that drain into PCWA's primary storage reservoirs, Hell Hole and French Meadows. Cloud seeding suspension criteria would be implemented in wet years to ensure the incremental runoff generated by the project would be within the historical range of hydrologic variability for the target watersheds.
