    The SGMA Weekly · Jun 29, 2026 · Friant-Kern's $200M Hits the Ground

    After years of slow restoration, federal dollars are about to meet dirt on the Friant-Kern Canal. This week's SGMA Weekly covers four Must Knows and three Trends from the past week of California water-agency board action. In this episode: • Friant Water Authority locks in a real groundbreaking date for the $200M Friant-Kern Canal subsidence fix — Phase 2A bid period July–August, October construction start, formal groundbreaking the week of August 17 • Five districts update their long-range water outlooks — the coast comes in flush (Carpinteria selling $840K of surplus state water with Cachuma at 94%, Amador with a 10–12K AF surplus), the valley sharpens (SSJID facing up to 26% dry-year shortfalls, San Benito's 2045 deficit driven by water quality not supply) • Cross Valley Canal expansion comes down to a tough choice — a parallel canal that keeps 500 CFS flowing during construction, or a widened channel that demands a 140-day shutdown • Golden mussel response moves from emergency awareness to month-by-month operations across the connected canals — Dudek evaluating chlorine dioxide and sodium hypochlorite for the Cross Valley Canal Plus three Trends: 2027 demand-management triggers getting drafted (Colusa, Arroyo Seco, Vina each picking their own logic), GSP five-year periodic evaluations opening public comment windows this summer, and Kern locking in dedicated capital funds for its 50-year-old conveyance assets.

  2. Subsidence Goalposts, Sites Reservoir at $1.36B, $200K Basin Fee — Jun 22, 2026

    Subsidence Goalposts, Sites Reservoir at $1.36B, $200K Basin Fee — Jun 22, 2026

    This week the Department of Water Resources is treating subsidence as "irreparable harm" requiring immediate action — a stance shift surfaced at three different boards this week (Chowchilla, North Kern, Omochumne Hartnell). The California Water Commission lifted Sites Reservoir's conditional funding ceiling to $1.36 billion as a September water-rights decision looms. The State Water Board is floating a $200,000 application fee just to request a basin exclusion — comments due July 10. Plus: Pajaro Valley and Desert Water Agency rate decisions hitting binding action, San Antonio Basin enforcement letters going out, the Tulare Lake sub-basin consolidating to a single state liaison, federal "One Big Beautiful Bill" money landing on Delta-Mendota Canal repairs, and conjunctive-use recharge gaining momentum across three different boards.

    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.

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

    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.

    Tule Allocation Math Under Audit, GEARS Bug, Prop 4 Push — May 11, 2026

    The State Water Board's denial of the remaining Tule Subbasin exclusion requests is opening into a deeper audit — state officials are now questioning local agencies' 34-year rolling precipitation averages, native sustainable yield calculations, and recharge-credit treatment, which could force structural changes to Basin Safe accounting in coming years. Porterville staff also reported the state is backing off the May 1 GEARS penalty after acknowledging a platform bug that doubled extraction totals for many manual filers (no formal State Water Board notice yet — sourced to PID staff). Plus: Kings and Kaweah growers face a compressed irrigation season with Kings River runoff in the mid-40% range, Mid-Kaweah pushes mandatory well registration with an October 31 target deadline, and the Prop 4 funding cycle starts pulling agencies into project-list mode while modeling and consulting costs become budget pressure points across subbasins.
