Idaho's biggest water story

August 30, 2024: ESPA curtailment

In response to a 2015 SWC settlement breach, IDWR issued a curtailment order shutting off ~6,400 ESPA-area junior groundwater rights. Within hours, holders began filing mitigation plans — the legal mechanism that lets a junior pumper continue pumping if they can demonstrate firm replacement water for the senior surface user. By November, the major GWDs had approved plans and pumping resumed. WMIS NextGen tracks every plan, every annual review, and every breach in one place — so leadership always knows who's protected and who isn't.
