View of Strawberry Peninsula and Richardson Bay in Mill Valley, California.  San Pablo Bay is in the background and the Richmond-San Rafael Bridge is in the upper right corner. With bedrock at or close to the surface in most of southern Marin County, mountain reservoirs on Mount Tamalpais in the Marin Municipal Water District's water shed serve most of the residents.

Conservation measures as well as more recycling of wastewater at the various Marin treatment plants, and other technical and engineering innovations, political cooperation and regional water alliances between water agencies will be part of the solution of providing a more dependable water supply during periods of drought.
