🔔 Tulare water managers brace for state action on excessive groundwater pumping

SJV Water — Thu, 16 Jul 2026 01:09:39 +0000

Reading Summary: Tulare Groundwater Pumping Crackdown

Key Facts

A closed-door meeting is scheduled between 12 Tule subbasin GSAs and State Water Resources Control Board member Nichole Morgan to discuss next steps in the state’s groundwater enforcement action
Local managers had nearly two years following a 2024 probationary ruling to produce a cohesive groundwater plan — none has materialized
State-mandated pumping limits are the next potential consequence, and would come with a $35 per acre-foot charge
The subbasin is targeting a rewritten Groundwater Sustainability Plan submission by June 2027; 11 of 12 GSAs have signed on to a unified plan effort
“Wild west” overpumping continues in the former Eastern Tule GSA where a lapse in oversight has left no enforceable rules in place

Who Is Affected

12 Tule subbasin GSAs (split from 6 following the 2024 ruling), including Tea Pot Dome, Pixley, and Lower Tule River GSAs
Friant Water Authority and users of the Friant-Kern Canal, which is suffering subsidence damage
Farmers in southern Tulare County, including Pixley-area growers like Mike Faria
Domestic well users whose water quality and access are at risk

Policy/Legal Angle

The meeting is a procedural step under California’s Sustainable Groundwater Management Act (SGMA), which empowers the State Water Board to intervene when local GSAs fail to manage overdraft
The 2024 probationary designation triggered a two-year compliance window that has not produced a new plan
Active lawsuits exist between multiple GSAs and Friant Water Authority over canal subsidence damage
A proposed zero-pumping buffer zone of 2–3 miles on either side of the Friant-Kern Canal is under negotiation

Blog Angles

The $35/acre-foot charge as a policy lever: How does this fee compare to actual water costs in the region, and is it punitive enough to change behavior — or just a pass-through cost for large growers?
The Eastern Tule governance vacuum: How did oversight collapse entirely in one GSA, who is pumping there now, and what legal mechanism can actually stop it?
Communication breakdown between locals and the Water Board: The “silo” complaint is notable — is this a structural flaw in SGMA implementation statewide, or specific to this subbasin’s conflict dynamics?

WELL Accepting Applications for Two Leadership Programs

ACWA — Wed, 15 Jul 2026 20:19:33 +0000

Reading Summary: WELL Accepting Applications for Two Leadership Programs

Key Facts

Water Education for Latino Leaders (WELL) is accepting applications for two programs simultaneously
Educate 2 Lead: targets mid-level managers in California’s water and energy sectors; involves four in-person sessions; application deadline is July 24
UnTapped Fellowship: a six-month, in-person program for local elected leaders focused on California water challenges and policy decision-making; application deadline is October 1
Both programs aim to build leadership capacity within Latino communities connected to California water governance
More information available at latinosforwater.org

Who Is Affected

Mid-level managers in California’s water and energy sectors (Educate 2 Lead)
Local elected officials across California (UnTapped Fellowship)
Latino communities underrepresented in water leadership and policy roles

Policy/Legal Angle

No specific laws or regulations cited; programs address an equity and representation gap in California water governance broadly covered under diversity and inclusion policy discussions

Blog Angles

Representation gap: How well are Latino leaders currently represented on California water boards, and do programs like WELL measurably change that?
Elected vs. staff training: Why does the UnTapped Fellowship specifically target elected officials rather than agency staff, and what does that reveal about where water policy knowledge gaps are greatest?
Pipeline to leadership: Are Educate 2 Lead alumni advancing into senior water agency roles, and can WELL document measurable career outcomes?

Pixley Irrigation District ‘hacking’ incident still under investigation

SJV Water — Wed, 15 Jul 2026 21:53:46 +0000

Reading Summary: Pixley Irrigation District ‘Hacking’ Incident

Key Facts

On June 22, the first day of Pixley Irrigation District’s summer water run, a gate at the district’s main turnout off Deer Creek was stuck in “manual” mode, preventing remote automatic operation
General Manager Alex Peltzer confirmed unauthorized access “jumbled the programming” for the gates; the problem was fixed within two hours and programming fully restored a couple of days later
Water Resources Superintendent Kirk Masters said he was told Iranian hackers were responsible, but this has not been confirmed; an FBI investigation is ongoing with no results reported yet
A separate Iranian hacker group attempted to breach California Water Service’s systems in Bakersfield, Visalia, and Chico on June 11, limited to one customer account and an external GPS website
No Pixley landowners were denied or delayed water delivery; remote access security has since been upgraded

Who Is Affected

Pixley Irrigation District (primary victim)
California Water Service customers in Bakersfield, Visalia, and Chico
Friant Water Authority (Friant-Kern and Madera canals) — proactively mentioned manual backup capability
Delano-Earlimart Irrigation District — neighboring agency expressing concern
San Joaquin Valley agricultural water users broadly

Policy/Legal Angle

No specific laws, regulations, or court decisions are cited in the article
The FBI investigation implies potential federal criminal jurisdiction over critical infrastructure cyberattacks
The Alliance of California Water Agencies (ACWA) is noted as an alert network for such incidents, suggesting an informal mutual-notification framework rather than a codified regulatory requirement

Blog Angles

How vulnerable is San Joaquin Valley water infrastructure? The near-simultaneous incidents at Pixley ID and Cal Water suggest a pattern — are Iranian state-sponsored actors specifically targeting California agricultural and municipal water systems, and what is the state or federal government doing systematically in response?
The manual backup gap: Friant Water Authority emphasized it can operate the Friant-Kern Canal manually if automated systems fail — do most small irrigation districts like Pixley have that same redundancy, or are they dangerously dependent on remote automation?
Transparency vs. security tension: Delano-Earlimart’s GM explicitly refused to discuss security details (“you never tell the adversary what you’re ready for”) — how much public disclosure should water agencies provide after a cyberattack, and does California have any reporting requirements for critical water infrastructure breaches?
