The Water Challenge: Doing More with Less

Hydrologic Context and Volatility

• California's hydrologic conditions have shifted from "happy land" to "red zone" conditions, with precipitation consistently falling below long-term averages.
• Tree ring studies reconstruct 1,100 years of hydrologic history in the Sacramento Valley, revealing that the 100-year average is flat-lined but the volatility in water supply has increased dramatically.
• The state has transitioned from a low-risk water environment to a high-risk world due to rising water demand coupled with natural volatility.
• State and federal water projects, the backbone of the Central Valley, provided zero allocations last year except for specific existing water users.
• The Central Valley economy and real estate development have historically relied on these unreliable project deliveries.

Agricultural Adaptation and Crop Economics

• Secretary Karen Ross projects that California's agricultural sector will adapt through continual changes in cropping patterns and a commitment to improved efficiency.
• California produces over 90% of the US broccoli, strawberries, and grapes, nearly 100% of tree nuts, and 75% of leafy greens, making these high-nutrition crops essential for global food security.
• Between 1967 and 2007, agricultural water use declined by 14.5%, while productivity per acre-foot of water increased by over 85%.
• Sensor technology, weather stations, and plant-level data on evapotranspiration and humidity are expected to drive future efficiency gains.
• Farmers are adapting by growing higher-value crops to maximize economic return per unit of water used.
• Moss Masumoto, a family farmer, notes that drought stress can increase flavor intensity in wine grapes and peaches, suggesting a potential market shift toward "stressed" produce.
• The concept of "fallowing" (taking land out of production) is expected to increase as capital investment shifts to crops with higher water value.

Water Rights, Regulation, and Groundwater

• Western water rights operate on a "first in time, first in right" seniority system, similar to senior debt holders versus junior creditors.
• The State Water Resources Control Board is currently managing the first large-scale curtailment of junior surface water rights (acquired after 1914) due to drought.
• New legislation requires the integrated management of surface water and groundwater, moving away from managing groundwater solely at the local level without state oversight.
• Groundwater management plans have a two-and-a-half-year deadline for initial stakeholder engagement, though full implementation will take longer.
• Meters are currently missing in many areas where water is used, a gap identified as a critical barrier to creating functional water markets.
• Curtailments on surface water users have largely been lifted, with only two areas (Scott Valley and one other) remaining under active restrictions at the time of the transcript.

Urban Water Management and Conservation

• Potable reuse is currently "stuck" in California due to a lack of proactive leadership, despite successful models in Orange County (since 2008) and San Diego.
• San Diego is aggressively investigating direct potable reuse, which augments drinking water with treated wastewater without an environmental buffer.
• Los Angeles currently hemorrhages nearly half of its rainfall, wasting 28 billion gallons in runoff even during the state's driest recorded year.
• Australia reduced per capita water use from 80 gallons to 33 gallons per day through a combination of incentives, penalties, and public education.
• Australian municipalities have installed millions of rainwater tanks ranging from 5,000 liters (residential) to 30,000 gallons (commercial), doubling local supplies.
• Direct potable reuse allows for the integration of highly treated recycled water directly into the drinking supply, removing the need for groundwater recharge buffers.
• Los Angeles Department of Water and Power (DWP) is developing a stormwater capture master plan aiming for a 30% increase in local supplies via distributed rainwater harvesting.
• Los Angeles is offering incentives of $375 per square foot for the permanent removal of turf to reduce landscape water consumption.

Pricing Strategies and Market Mechanisms

• Water utilities face a challenge where 90% of costs are fixed, creating a mismatch between traditional pricing models and drought-era rationing.
• Water rates have increased from an average of $30 to $60–$70 over the last 12 years, with projections suggesting the average bill could exceed $100 within four to five years.
• "Water budget" rate structures are being implemented (e.g., Elsinore Valley, El Toro) to price essential health needs cheaply while progressively increasing costs for wasteful or excessive outdoor use.
• Desalination is identified as the most expensive water source, likely to be adopted only after conservation, stormwater capture, and recycling options are exhausted.
• In a recent auction, agricultural users bid $1,000 per acre-foot for water to protect permanent crops, signaling a new valuation of reliability.
• The "water-energy nexus" is a critical focus, as pumping water for Los Angeles is the largest single electricity use in the state; saving energy by harvesting local rainwater could be a priority for utilities.
• Behavioral economics research highlights "left digit bias," where consumers ignore bills unless the left-most digit crosses a certain threshold, suggesting pricing and feedback mechanisms need psychological optimization.

Infrastructure and Future Investment

• The Bay Delta Conservation Plan (BDCP), a $25 billion project, is a high priority for Governor Brown to modernize the fragile ecosystem and ensure water conveyance.
• The BDCP is designed to increase efficiency and protect wildlife, not to create new water supplies.
• Above-ground storage projects are being evaluated, with the consensus that integrated storage (groundwater, reservoirs, recycled water) is essential for drought resilience.
• Graywater systems are gaining traction following plumbing code changes, though installation is difficult in existing homes and relies on local district support.
• Australia's experience with desalination serves as a cautionary tale: plants built during peak drought panic were largely unused once conservation lowered demand, yet remain as insurance policies.
• A December 9–10 event in Sacramento will bring Australian water authorities and technology companies to California to share lessons from the "sea change" in Australian water management.
• The California Water Action Plan emphasizes a comprehensive, integrated approach over the next 5–10 years rather than relying on a single "silver bullet" solution.
