Why It Matters
Dozens of Butte County farmers who planted crops this spring remain unable to turn on their irrigation pumps after the state ordered wells shut off to protect senior water rights holders. A last-minute joint request filed Friday could restore water access while technical negotiations continue, potentially saving this season’s harvests.
The dispute centers on three groundwater districts in the Big Lost and Little Lost River basins that state regulators say missed a November deadline to join a mitigation plan required under Idaho’s water priority system.
What Happened
The Surface Water Coalition and Idaho Ground Water Appropriators submitted a joint petition to the Idaho Department of Water Resources on April 17 requesting a temporary pause in enforcement of the curtailment order. The filing came one day after IDWR Director Matt Weaver denied an earlier motion to stay the shutdown.
The joint request asks the state to allow groundwater users to resume pumping through at least May 4 while all parties complete a technical review. The review would determine whether the three districts can be added to an existing 2024 mitigation plan without harming current participants.
Alan Hansten, chairman of the Surface Water Coalition, said his group recognizes the hardship facing Butte County producers. The coalition had previously defended the curtailment decision, praising Director Weaver for following constitutional water law.
By the Numbers
181,600 acre-feet: Projected water shortfall for senior surface water rights holders this season
April 17, 2026: Date of joint stay request filing at 2:00 p.m.
May 4, 2026: Proposed deadline for completing technical review
November 2025: Deadline the three districts allegedly missed for joining mitigation plan

Zoom Out
Idaho operates under the prior appropriation doctrine, which grants water access based on seniority of claims. During drought conditions, junior rights holders must curtail pumping to ensure senior users receive their full allocation.
Senate Bill 1341 required junior groundwater users in the affected basins to join approved mitigation plans by last November to avoid curtailment. State regulators determined the three districts failed to meet that deadline, triggering the shutdown order.
The Idaho Ground Water Appropriators disputes that timeline. Executive Director Lara Herway said member farmers acted in good faith and completed all required steps. Kirk Nickerson, chairman of the Little Lost River Ground Water District, expressed disappointment that the curtailment went forward despite his district’s efforts to join the mitigation framework.
State Representative Stephanie Mickelsen, who also serves as IGWA president, called the joint request an example of water users setting aside disagreements to protect Idaho agriculture during a critical period.
What’s Next
The Idaho Department of Water Resources will review the joint petition and decide whether to grant the temporary stay. If approved, affected farmers could resume irrigation immediately while technical experts evaluate whether adding the three districts to the existing mitigation plan is feasible.
Surface Water Coalition leadership emphasized that any agreement must comply with Idaho constitutional law protecting senior water rights and maintain the integrity of the 2024 Mitigation Plan. Hansten said all parties remain committed to reaching a solution grounded in sound data and fair to all water users across the state.
