Strategic Water Supply Assessment
Improving our water supply security to address the impacts of climate change
Severe conditions brought on by the drought over the last several years have intensified the district’s focus on strengthening the reliability of its water supply. The District is currently conducting a Strategic Water Supply Assessment intended to evaluate the Districts current baseline water supply in the context of climate-change-driven droughts and to evaluate the impact of potential future water management alternatives that could improve the District’s long term water supply resiliency. These efforts will help the district ultimately determine which options are viable, affordable, and make the most sense for our community and the region. This webpage will be periodically updated as there is new information to share.

Strategic Assessment
The District has initiated a strategic assessment of various water management alternatives that could support community water needs in times of future shortages. The effort is intended to:
- Build on extensive previous water supply planning efforts and incorporate new options
- Evaluate current risk to District’s water delivery reliability under recent and future extended drought scenarios
- Determine a timeline for developing alternative water management options to maintain resiliency
- Water Transfers with Conveyance through Bay Interties
- Sonoma-Marin Partnerships
- Local Supply Enhancements
- Desalination
- Recycled Water
- Water Conservation
About Our Water Supply & Usage
The district provides 100 percent locally sourced drinking water to its 191,000 customers. A total of 75 percent of that water supply is captured and stored in the district’s seven reservoirs, which include Phoenix, Lagunitas, Bon Tempe, Alpine and Kent on Mt. Tamalpais, and Nicasio and Soulajule in west Marin. Together, these reservoirs hold 79,566 acre-feet of water, or about 30 billion gallons. The remaining 25 percent of our water supply comes from neighboring Sonoma County’s Russian River water system.
