315 P.3d 828
Idaho2013Background
- The dispute concerns a 2005 delivery call by senior surface water right holders (Surface Water Coalition) alleging material injury from junior groundwater pumping (Idaho Ground Water Appropriators) in the hydraulically connected Snake River Basin.
- IDWR Director issued a series of orders adopting a baseline methodology (initially called “minimum full supply,” later “reasonable in-season demand”) projecting senior needs and using predicted shortfalls from that baseline to identify material injury; replacement-water plans were ordered of juniors.
- A hearing officer largely approved the baseline approach but recommended refinements and procedural protections; the Director adopted much of that report but issued bifurcated final orders and declined to treat replacement plans as formal mitigation plans.
- The district court affirmed use of a baseline but found the Director abused his discretion by: (1) approving replacement plans that circumvent mitigation-plan procedures, (2) limiting carryover storage protection to one year, (3) misapplying evidentiary burdens on a headgate-delivery measure, and (4) issuing separate final orders; it remanded for refinements.
- On further proceedings the Director issued a methodology order; this appeal challenges (a) the permissibility of a predictive baseline in determining material injury, (b) whether out-of-priority diversions require a properly enacted mitigation plan, (c) whether bifurcated final orders were improper, and (d) the applicable evidentiary standard (Coalition argued for clear-and-convincing; juniors and City urged preponderance).
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| 1. May the Director use a predictive baseline (minimum full supply / reasonable in-season demand) to determine material injury? | Coalition: Baseline re-adjudicates decreed/licensed rights and improperly shifts burden to seniors to re-prove their rights. | Director / Groundwater users: Baseline is a reasonable management tool; Director may predict senior needs for allocation and administration. | Held: Director may use a baseline as a starting point for management and administration, provided it accords with prior-appropriation principles, is published in advance and updated, and evidentiary presumptions/burdens are observed. |
| 2. Do Conjunctive Management Rules permit out-of-priority diversions absent a properly adopted mitigation plan? | Coalition: Replacement plans used here improperly circumvent Rule requirements; seniors need assurances for carryover protection. | Director: Replacement plans are necessary to make seniors whole during proceedings and juniors would be harmed by immediate mitigation-plan requirements. | Held: Rules require out-of-priority diversions only pursuant to a properly approved mitigation plan that includes contingency assurances; Director abused discretion by approving replacement plans that bypass mitigation procedures. |
| 3. Did the Director err by bifurcating his final order (issuing separate final orders) instead of a single final order? | Coalition: Bifurcation undermines judicial review and violates APA timing/procedural rules. | Director: Subsequent methodology order addressed issues; later process cured defects. | Held: Coalition failed to preserve the issue on appeal (did not timely object to the later methodology order); court did not grant relief on bifurcation. |
| 4. What evidentiary standard applies to junior’s proof that a delivery call is unfounded or futile? | Groundwater users & City: Preponderance of evidence is sufficient. | Coalition / District Court: Clear and convincing standard applies to justify changes to decreed rights. | Held: Clear and convincing evidence is the required standard; this Court had affirmed that rule in A & B Irr. Dist. v. IDWR. |
