Indian Wells Goes to Trial, Kern Tightens Subsidence Rules — Jun 15, 2026

A California court enters Phase 2 of the Indian Wells Valley safe-yield trial — testing how a court-adjudicated number will line up against a GSA's SGMA sustainable-yield. Kern Subbasin moves to a stricter "critical head" subsidence standard tied to DWR's January 2026 BMPs. Plus: Tule advances a 20-year land repurposing program, Salinas weighs a deep-aquifer pumping moratorium, and the well-registration enforcement era gets real across multiple basins.

McMullin's $56M Vote, $176M Federal Awards, and a Brewing Aqueduct Cost Fight — Jun 8, 2026

McMullin Area GSA's Proposition 218 election just passed in a landslide to fund a $56M flood capture expansion. The Bureau of Reclamation announced $176M in fresh Aging Infrastructure awards for the Delta-Mendota Canal and O'Neill Pumping Plant, with a $37.5M Kiewit contract approved to start the first canal subsidence fix. And a federal letter to DWR just opened up the larger ~$3B California Aqueduct Subsidence Program cost-share fight. Plus: White Wolf sharpens subsidence rules along the Aqueduct, Salinas Valley faces an August DWR deadline on a controversial brackish project, snowpack collapses to 6% of normal, and federal grant paperwork lags the cash.

Federal Canal Money, Snowpack Collapse, and Oakley's Data-Center Pause — Jun 1, 2026

Federal canal-repair money just hit California in a big way: $200M to Friant-Kern, $235M to Delta-Mendota, and $50M to the San Luis Canal — totaling $485M+ in OBBB / Bureau of Reclamation investments discussed across this week's board meetings. Meanwhile, the snowpack supplying it all just collapsed to 3.5% of normal in the Tuolumne basin — a depth-of-collapse not seen since 1977. And Oakley extended its data-center moratorium another 10½ months, landing right inside Diablo Water District's service area.

Allocations Climb, Storage Slips, and Southwest Kings Closes Loopholes — May 24, 2026

DWR raised the State Water Project allocation from 30% to 45% on May 15 and Reclamation lifted the CVP South-of-Delta agricultural allocation from 20% to 25% — but statewide groundwater storage still declined by roughly 1.5 million acre-feet in Water Year 2025, with 83% of extractions concentrated in the San Joaquin Valley. Pajaro Valley, Omochumne Hartnell, and Mound Basin all surfaced selective cost-relief signals for ratepayers this week, while Southwest Kings GSA stayed implementation of its allocation policy to close out-of-county and carryover loopholes ahead of a coordinated Tulare Lake single-GSP push targeting Q1 2027. Plus the Prop 4 Climate Bond ($368M statewide, no local match) starts driving real grant-prep across agencies, and the next wave of SGMA fee adoptions and Prop 218 hearings rolls through Yolo, Wyandotte Creek, Mound Basin, Desert Water Agency, Pajaro Valley, and South Fork Kings.

Tule Interim Plan by the Board, Metropolitan Banking Deal, Karla to ACWA — May 18, 2026

The State Water Board's Tule interim plan is taking shape — staff revealed it could limit allocations to native safe yield only (under 0.25 AF/acre) with a 2-mile pumping moratorium and $20/AF probationary fees. Plus: four Valley GSAs hired Ewell Group to formalize a ~100,000 AF banking deal with the Metropolitan Water District; DWR Director Karla Nemeth departs July 2 to run ACWA; and golden mussels hit peak spawning with Arvin-Edison's Phase 1 copper treatment killing >90% at ~$3M. Trends: AB 2447 (nitrogen-limits bill) held in Appropriations, snowpack collapse compresses delivery windows, and Prop 4 funding prep moves from awareness to project lists.
