🔔 SJV WATER: The uneven toll of California’s groundwater law

Maven’s Notebook — Sat, 27 Jun 2026 18:57:34 +0000

By Hannah Johansson, SJV Water For Amrik “Mickey” Singh Basra, owning 300 acres of almonds in Madera County was more success than he ever expected to achieve in the United States. Approaching retirement age, he could let his trucking business go and envision the last decades of his life sustained by his orchard. Then two years ago, as his land value plummeted and he couldn’t repay a crop loan, he …

🔔 Betting on Lake Mead’s Demise

Circle of Blue — Sun, 28 Jun 2026 12:30:00 +0000

Reading Summary: “Betting on Lake Mead’s Demise”

Key Facts

As of June 27, Lake Mead sits at 1,044.9 ft., just 4.3 ft. above its record low of 1,040.6 ft. (set July 2022); the reservoir is 28% full
Below 1,035 ft., hydropower generation at Hoover Dam drops 70% because 12 of 17 turbines cannot safely operate at low water levels
The Bureau of Reclamation was authorized to spend $52 million on Hoover Dam infrastructure upgrades, including up to three “wide-head” turbines operable down to 950 ft. elevation
Winning turbine bidders have two years to deliver; Reclamation’s June projections show Mead could fall to 1,015 ft. by July 2027
Prediction market Kalshi is offering wagers on Mead’s end-of-June water level, a rare water-specific financial instrument

Who Is Affected

Bureau of Reclamation (dam manager, contracting authority)
Cities, farms, and high-tech industries dependent on Colorado River system water
Downstream ecosystems tied to river flows
Power customers reliant on Hoover Dam hydropower

Policy/Legal Angle

No specific legislation or court decisions cited, but the $52 million authorization for Hoover Dam upgrades reflects a federal infrastructure response to crisis conditions
Bureau of Reclamation’s request for proposals (RFP) process (issued June 10) is the active regulatory/procurement mechanism; additional RFPs are described as ongoing due to varying turbine design requirements

Blog Angles

The 1,035 ft. threshold as a policy trigger: What contingency plans exist if Mead breaches this level before the new turbines are delivered? A two-year delivery timeline vs. a projected 2027 low of 1,015 ft. raises urgent questions about the gap in protection.
Who bears the hydropower loss?: If generation drops 70%, which utilities, states, or ratepayers absorb that hit — and are there existing contracts or shortage-sharing agreements that govern this?
Prediction markets as water data: Does Kalshi’s thinly traded Lake Mead market reflect genuine risk pricing, and could deeper prediction markets eventually serve as a policy signal or complement to official forecasting tools like Reclamation’s own projections?

Commentary by Sacramento County Supervisor Patrick Hume & Contra Costa County Supervisor Shanelle Scales-Preston California’s water system depends on a simple principle: everyone plays by the same rules. Assembly Bill 2215 (Calderon) would break that principle and set a troubling precedent for the future of water management in our state. If you take water from a lake, river, stream, or creek, or f…

NOAA FISHERIES: New eDNA tool to help track recovery of sunflower sea star, a Pacific Coast ‘apex predator’

Maven’s Notebook — Sat, 27 Jun 2026 18:53:09 +0000

From NOAA Fisheries: A wasting disease that surged during the intense 2013-2016 Pacific marine heatwave known as the Blob decimated numerous species of sea stars and triggered the collapse of vast coastal kelp forests from the Aleutians to the Baja Peninsula. One of the species most affected was the sunflower sea star, an apex predator that feeds on kelp grazers like sea urchins. As captive breedi…

🔔 A Tributary Approach to Learning the Colorado River

CA Water Blog (UC Davis) — Sun, 28 Jun 2026 11:00:00 +0000

Reading Summary: A Tributary Approach to Learning the Colorado River

Key Facts

The article was written by three UC Davis graduate students (a groundwater researcher, a water modeler, and a policy nerd) who rafted the Yampa River as part of the Climate Adaptation Science Academy Experiential Learning Expedition (CASA ELE), organized by Secure Water Future.
The Colorado River supplies water to approximately 40 million people across two countries, seven U.S. states, and 30 federally recognized tribal nations.
Existing rules governing the Colorado River’s reservoir operations are set to expire at the end of 2026, with negotiators deadlocked on a consensus replacement agreement.
As of winter 2026, projected inflow into Lake Powell was nearing record lows, compounding two decades of declining hydrology and reservoir storage.
California’s Colorado River and Sacramento-San Joaquin Delta systems are functionally linked: bad Colorado years increase Delta water demands, and good Northern California years allow water to remain in the Colorado system.

Who Is Affected

40 million water users across the Southwest, including irrigators in the Imperial Valley and urban users in Southern California
30 federally recognized tribal nations within the Basin
UC Davis graduate students and the broader academic/research community
California’s Colorado River Board, represented by Commissioner JB Hamby
Aquatic and terrestrial ecosystems, including along the Yampa River (one of the West’s few remaining free-flowing rivers)
Farmers relying on the Sacramento-San Joaquin Delta when Colorado River supply tightens

Policy/Legal Angle

The article references a Record of Decision for the Near-Term Colorado River Operations Supplemental Environmental Impact Statement, governing current operational rules
Current interstate operating guidelines are expiring end of 2026, triggering high-stakes renegotiation among seven basin states
Legal water rights across the basin far exceed actual supply — the foundational tension underlying all negotiations
JB Hamby (California’s top negotiator) participated in the seminar, offering insight into closed-door interstate talks — suggesting California’s negotiating posture is a live policy flashpoint

Blog Angles

The 2026 deadline as a pressure point: With operating rules expiring and negotiators deadlocked, what are the realistic scenarios — a new consensus agreement, federal intervention, or litigation? What would California’s fallback position look like under each?
The Delta-Colorado linkage: The article briefly but provocatively notes that Northern and Southern California water systems are operationally interdependent. How often is this connection discussed in public water policy debates, and what does it mean for Delta water users when the Colorado River struggles?
Tribal inclusion in negotiations: The Basin spans 30 federally recognized tribal nations, yet the seminar’s framing of equity and fairness raises the question — how meaningfully are tribes represented in the closed-door interstate talks JB Hamby described?
