AB 1146 creates a new prohibition on releases of stored water from reservoirs owned and operated by the United States in California when those releases are made "under false pretenses," defined as knowingly and intentionally misrepresenting the purpose or intended use of the water. The bill shifts enforcement away from misdemeanor prosecution toward civil enforcement: the State Water Resources Control Board may issue interim relief orders to stop suspected unlawful releases, and the Attorney General or the board may seek injunctive relief in court.
The bill imposes civil liability of up to $10,000 per day for each violation and expressly provides that those penalties apply to the United States only to the extent federal law permits. It also spells out collection options if the federal government declines payment, including allocating fees to water contractors or refusing to process applications tied to unpaid fees.
For professionals in water management, environmental compliance, and municipal water delivery, the measure creates a new cause of action, emergency remedy, and an unusual interface between state enforcement and federal reservoir operations.
At a Glance
What It Does
AB 1146 forbids releases of stored water from U.S.-owned reservoirs in California made under "false pretenses" and defines that term as knowingly and intentionally misrepresenting the purpose or intended use of the water. It empowers the State Water Resources Control Board to issue interim relief orders (including emergency orders without prior hearing) and authorizes civil penalties up to $10,000 per day, plus injunctive suits by the board or Attorney General.
Who It Affects
Federal reservoir operators (e.g., Bureau of Reclamation, Army Corps of Engineers), California water contractors and districts that receive federally stored water, the State Water Resources Control Board and Attorney General, downstream legal water users and environmental beneficiaries reliant on instream flows.
Why It Matters
The bill inserts California enforcement tools into the management of federally owned reservoirs, creates daily civil liability tied to intent, and builds procedural mechanisms to halt suspected fraudulent releases quickly—raising novel state-federal interaction issues and operational risks for federal reservoir managers and their contractors.

What This Bill Actually Does
The bill makes a narrow but potentially powerful change: it prohibits any release of stored water from a reservoir owned and operated by the United States in California when the release is made under false pretenses. "False pretenses" is defined as an intentional, knowing, and designedly fraudulent misrepresentation about the purpose or intended use of the water. That focused definition ties the new prohibition to the operator's state of mind rather than to incidental mistakes or disagreements about allocation.
Enforcement shifts away from criminal misdemeanor treatment to civil remedies and emergency administrative orders. The State Water Resources Control Board (the board) can issue an interim relief order to stop a release suspected of violating the new prohibition and can start that proceeding on its own motion.
The usual procedure requires at least 10 days’ notice before a hearing, but the board can issue an interim order without a prior hearing if it finds immediate compliance is necessary to prevent public harm, harm to other legal users, or to instream beneficial uses. A party subject to an emergency order can demand a hearing within 15 days, and any interim order generally expires after 30 days unless extended by agreement.Civil penalties replace the misdemeanor route for these violations.
The bill imposes civil liability of up to $10,000 for each day the violation continues and expressly states that these penalties apply to the United States only to the extent federal law permits. The board gets several practical tools for situations where the federal government declines to pay: pursue collection actions when federal law allows, allocate the obligation to parties with delivery contracts, enter reimbursement contracts with the United States, or refuse to process certain applications if unpaid fees would not conflict with federal law or the public interest.
Finally, the bill authorizes the board and the Attorney General (either on behalf of the board or independently) to seek temporary restraining orders, preliminary injunctions, or permanent injunctions when a release is threatened, occurring, or has occurred in violation of the new rule.Taken together, AB 1146 creates a fast-moving enforcement pathway for the State to stop and remedy releases it views as fraudulently motivated, ties liability to proof of intent, and builds mechanisms to try to recover penalties even when the federal government asserts immunity or declines to pay. That package alters the enforcement landscape for federal reservoir operations within California's borders and forces operators and contractors to factor state administrative and civil remedies into operating decisions.
The Five Things You Need to Know
The bill defines "false pretenses" as a release that is knowingly, designedly, and intentionally made under false or fraudulent representations about the purpose or intended use of the water.
The State Water Resources Control Board may issue an interim relief order to prohibit a stored-water release and can commence the proceeding on its own motion.
The board must provide at least 10 days' notice before a hearing unless it issues an emergency interim order; if the board issues an emergency order, the affected party can request a hearing within 15 days and the order lasts up to 30 days unless extended by agreement.
Civil liability is capped at $10,000 for each day a violation occurs, and those penalties apply to the United States only to the extent allowed by federal law (including reference to the McCarran Amendment).
If the United States declines to pay, the board may try to collect where federal law permits, allocate fees to water delivery contractors, contract for reimbursement, or refuse to process applications tied to unpaid fees when consistent with federal law and the public interest.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Prohibits releases under 'false pretenses' from U.S.-owned reservoirs
This section creates the substantive offense: a release of stored water from a reservoir owned and operated by the United States in California is prohibited when carried out under "false pretenses." The definition requires proof that the release was knowingly, designedly, and intentionally based on a false or fraudulent representation of purpose or intended use. That narrow mens rea focuses enforcement on deceptive conduct rather than operational disagreements.
Board may issue interim relief orders and set emergency procedures
The board receives a new administrative enforcement tool: it can issue interim relief orders to prohibit releases it believes violate Section 6033 and may initiate those proceedings without an external complaint. The bill sets procedural guardrails: typically 10 days' notice before a hearing, but the board can issue an interim order without prior hearing if it finds immediate compliance is necessary to avoid public harm, injury to other legal water users, or harm to instream beneficial uses. A party subject to an emergency order can demand a hearing within 15 days, and the interim order expires after 30 days unless extended by agreement. Practically, this provision lets the board act quickly to stop a release while preserving prompt post-order process.
Board and Attorney General can seek temporary or permanent injunctions
Complementing the administrative remedy, the statute authorizes the board, the Attorney General on behalf of the board, or the Attorney General independently to bring actions for temporary restraining orders, preliminary injunctions, or permanent injunctions when a release is threatened, occurring, or has occurred in violation of Section 6033. That dual pathway—administrative emergency orders plus judicial injunctive relief—gives California both quick-stop and longer-term remedies to halt or reverse unlawful releases.
Moves enforcement from misdemeanor to civil penalties and addresses federal recoveries
This amendment removes Section 6033 and board orders under Section 6034 from the misdemeanor penalty regime in Section 6425 and instead imposes civil liability up to $10,000 per day for each day a violation continues. The amendment expressly applies those penalties to the United States only to the extent federal law allows (citing the McCarran Amendment). It also gives the board practical options if the United States declines to pay: initiate collection when law allows, allocate fees to water contractors with delivery contracts, enter reimbursement contracts, or refuse to process certain applications tied to unpaid fees—subject to federal-law constraints and public-interest considerations.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Downstream legal water users (municipalities, irrigation districts) — gain a state enforcement avenue to stop releases they believe were fraudulently diverted and to protect contracted deliveries.
- Instream and environmental beneficiaries (fish, habitat protection groups) — receive a quicker administrative tool the board can use to prevent releases that would harm instream beneficial uses.
- State regulators (State Water Resources Control Board and Attorney General) — obtain explicit statutory authority to act rapidly (interim orders) and pursue civil remedies and injunctions against suspected fraudulent releases.
Who Bears the Cost
- Federal reservoir operators (Bureau of Reclamation, U.S. Army Corps of Engineers) — face potential daily civil exposure and administrative interference from state orders, subject to federal-law limits and likely litigation.
- Water contractors who receive deliveries from federal reservoirs — risk being allocated fees or assessed portions of penalties if the board exercises its allocation authority when the federal government declines payment.
- The State Water Resources Control Board and Attorney General — bear increased enforcement workload, administrative hearing responsibilities, and litigation obligations; those activities may require resources and prompt decision-making under short deadlines.
Key Issues
The Core Tension
The bill pits California's interest in preventing and remedying fraudulent water releases and protecting downstream and instream uses against limits on state authority over federally owned reservoirs: it aims for strong, quick enforcement but must operate within federal supremacy, sovereign-immunity constraints, and the practical realities of proving intentional deception without disrupting legitimate federal operations.
The bill confronts a difficult enforcement boundary: it asserts state-level civil and administrative tools against releases from federally owned reservoirs while acknowledging that penalties apply to the United States only where federal law permits. That caveat is meaningful—federal sovereign immunity and supremacy issues, plus the McCarran Amendment's narrow waiver limited to certain suits, will govern how far California can collect or enforce penalties against federal operators.
The practical reach of the bill's remedies depends on complex federal-law questions and likely litigation over whether the board can impose or allocate fees tied to federal operations.
The intent-based definition of "false pretenses" narrows the target but creates evidentiary challenges: proving release was "knowingly, designedly, and intentionally" misrepresented will often require internal agency records, communications, or admissions. The board's emergency-order authority lowers the procedural bar for immediate relief, which helps prevent imminent harm but also risks freezing necessary operational releases (for flood control or compliance with federal environmental mandates) while parties litigate.
Allocating penalties to water contractors or refusing to process applications as collection tools could shift fiscal burdens onto local entities that may have no role in the alleged misrepresentation, raising fairness and contractual risk concerns.
