Document Description
The Marin Municipal Water District (District) is proposing the Atmospheric River Capture Project (Project) to deliver water under the District’s existing agreement with the Sonoma County Water Agency (Sonoma Water) to Nicasio Reservoir for storage to improve water supply reliability under dry conditions. The Project would include construction and operation of an approximately 13.2-mile-long, 36-inch diameter water transmission pipeline within Wood Hollow Drive, Redwood Boulevard, San Marin Drive, Novato Boulevard, Point Reyes–Petaluma Road, and Nicasio Valley Road. The pipeline, referred to as the Nicasio Aqueduct, would convey water from the existing North Marin Aqueduct to Nicasio Reservoir. In addition, the Project would include two pump stations and a dechlorination facility. The Project would not increase the existing storage capacity of Nicasio Reservoir and would not modify the District’s existing agreement with Sonoma Water. The Project would deliver contract water from Sonoma Water for storage in Nicasio Reservoir during periods of high-flow events (i.e., atmospheric river events) for use by the District during dry conditions to improve water supply reliability.
