Planner reasoning

This is a niche regulatory question about Idaho Department of Water Resources curtailment orders in the long-running Surface Water Coalition delivery call against ground water users. Resolution depends on (a) whether the 2024/2025 mitigation settlement between IDWR, IGWA, and the SWC holds through 2027, (b) hydrologic conditions (snowpack, reservoir carryover, Eastern Snake Plain Aquifer levels) driving predicted shortfall, and (c) historical counts of rights listed in curtailment orders. The Kalshi price is the primary anchor; news search is essential since IDWR actions are covered by Idaho outlets but not major national corpora.

# Current state IDWR's operative curtailment orders under the Surface Water Coalition delivery call have listed 743 groundwater rights (2025 order) and 924 groundwater rights (May 2026 order); both are far above the 500 threshold. Kalshi currently prices "Above 500" at 94% for the 2027 season. The underlying 2024 mitigation settlement remains in effect but is up for renewal review in fall 2027, and 2026 drought/shortfall conditions were the worst on record, with poor snowpack heading into 2027. # Timeline of key events - 2024 (irrigation season start): Four-year Stipulated Mitigation Plan/settlement between IGWA, SWC, and IDWR takes effect, replacing 2015 pact (confirmed, postregister.com). - 2025-07 (reported): IDWR July 2025 order lists 743 groundwater rights subject to curtailment; 469 later resolved via approved mitigation plans (aginfo.net, confirmed). - 2025-11-21 (confirmed): Curtailment order takes effect for Big Lost/Little Lost basins; three districts fail to join approved mitigation plan by deadline. - 2026-03 to 2026-04 (confirmed): IDWR checks wells, finds continued non-compliance; localnews8.com reports IDWR denies stay request (2026-04-16), Butte County pumps remain off. - 2026-04 (confirmed): IDWR issues drought declaration; predicted 2026 shortfall of 181,600 AF (~2.4x 2025's 75,300 AF). - 2026-05-14 (confirmed): IDWR Final Order Curtailing Ground Water Rights junior to Oct 11, 1900 — headline figure 924 groundwater rights targeted (eastidahonews.com). - 2026-05-01 (confirmed): Joint Motion filed for Amended 2026-2027 Interim Stipulation (docket CM-MP-2026-003) — active mitigation stipulation mechanics continuing into 2027. - 2026-05 (reported): East Idaho snowpack at 16-35% of normal; moderate-to-exceptional drought across south-central/eastern Idaho. - 2026-06 (confirmed, multiple outlets): SWC announces "drastic water cuts" amid one of worst water outlooks on record; farmers abandoning fields. - 2026-07-24 (confirmed): Idaho curtailment order "ups expected shortfall" (capitalpress.com). - 2026-08-19/21 (confirmed): IGWA/SWC/IDWR stakeholders begin early discussions on renewing Eastern Snake water pact ahead of fall 2027 review; parties say settlement "working well." # Event Will IDWR's operative 2027-season curtailment orders under the SWC delivery call list more than 500 groundwater rights as of Oct 31, 2027? # Outcomes to forecast - Yes (>500 rights listed) - No (≤500 rights listed) # Kalshi market anchor **94% YES** (Above 500), up +1% over both 7-day and 30-day windows; range 93-94%; avg daily volume 619 contracts. Market is confident curtailment lists will again exceed 500. # Sub-question answers 1. **Historical curtailment size**: 2025 order = 743 rights; 2026 order = 924 rights (eastidahonews.com, aginfo.net). 500 is a low threshold relative to recent history — both recent years cleared it by 240-425 rights. 2. **Settlement status**: The 2024 four-year mitigation settlement remains active through 2027 and is described as "working well" (capitalpress.com, Aug 2026); it's due for renewal review in fall 2027. Compliance is imperfect — Butte County districts fell out of compliance in 2025-26, showing safe harbor doesn't universally prevent curtailment even under an active pact. 3. **2027 predicted shortfall**: No explicit 2027 methodology-order figure found; 2026 shortfall was 181,600 AF (2.4x 2025). No signal 2027 will be materially better; poor snowpack (16-35% normal, May 2026) suggests continued/comparable severity risk. 4. **Hydrologic conditions**: Severe drought across south-central/eastern Idaho; East Idaho snowpack 16-35% of normal (May 2026); water managers explicitly warn 2027 risk depends on winter 2026-27 snowpack recovery (postregister.com). No 2027 winter data yet available in research. 5. **Legal/administrative changes**: No pending court rulings or rule changes found that would reduce curtailment scope; active stipulation amendments (CM-MP-2026-003) are procedural, not structural rollbacks. Settlement renewal negotiations starting but outcome undetermined. 6. **Past order scale/fate**: Both 2025 and 2026 orders numbered in the hundreds (743, 924), not just low hundreds; some rights get resolved intra-season via mitigation plan enrollment (469 of 743 in 2025) but starting lists remain listed as "subject to curtailment" — relevant to how the question counts "listed" rights, which appears to capture the gross order figure, not the post-resolution net. # Key facts (high-confidence, factual) 1. [aginfo.net] 2025 order: 743 groundwater rights subject to curtailment. 2. [eastidahonews.com] 2026 order (May 14, 2026): 924 groundwater rights targeted. 3. [eastidahonews.com] 2026 predicted shortfall: 181,600 AF, ~2.4x 2025's 75,300 AF. 4. [capitalpress.com] Mitigation settlement (2024-2027) remains in effect and functioning as of Aug 2026; review scheduled fall 2027. 5. [postregister.com] East Idaho snowpack 16-35% of normal as of May 2026; drought risk for 2027 hinges on winter 2026-27 recovery. 6. [localnews8.com] Some districts (Butte County) failed compliance and faced curtailment despite active settlement (2025-26). # Cross-market signals - Kalshi related: No direct related IDWR series markets found; unrelated Idaho Senate market surfaced (no signal). - Polymarket: No matching markets found. - Sportsbook implied: N/A (not applicable to this event type). # Analyst opinions and speculation - claude_news synthesis: given base rates well above 500 in both preceding years and severe/worsening drought trajectory, a sub-500 2027 order would require an unusually wet 2026-27 winter or major mitigation-compliance expansion — neither confirmed. - Stakeholders (IGWA attorney) characterize settlement as generally successful, implying continued incentive to maintain mitigation compliance, but this hasn't prevented list sizes from growing 2025→2026. # Directional lean per outcome - **Yes (>500)**: Strongly supported — two consecutive years (2025, 2026) each far exceeded 500; worsening drought/shortfall trend; settlement renewal uncertain for fall 2027; Kalshi prices 94%. - **No (≤500)**: Would require a sharp reversal — exceptional winter 2026-27 snowpack, expanded mitigation plan compliance, or settlement renewal that materially shrinks curtailment scope. No current evidence supports this; 2026-27 winter data not yet available. # Gaps / unknowns - No 2027-specific methodology order or predicted shortfall figure yet (order likely issues later in 2026/early 2027). - Winter 2026-27 snowpack/precipitation data not available in research — key swing factor. - Uncertain whether "listed" count in question means gross initial order figure or year-end net after mitigation resolutions (2025 saw 743→469 resolved), which could affect edge cases but unlikely to swing below 500 given magnitude. - Fall 2027 settlement renewal outcome unknown as of research cutoff. # Calibration anchors - Kalshi current YES price: 94% (anchor). - Precedents: 2025 order = 743 rights; 2026 order = 924 rights — both far above 500 threshold, supporting continuation of trend.

1. Both forecasters anchor tightly at 94% but neither explores the fall 2027 settlement renewal as a genuine tail risk — the brief notes the review is "scheduled fall 2027" with "outcome undetermined," and a renegotiated pact expanding safe-harbor/mitigation enrollment could sharply cut the *operative* curtailment list even if underlying shortfall risk stays high; this scenario deserves more explicit weight than a passing mention. 2. Neither forecast adequately addresses the measurement ambiguity flagged in the brief: "listed" could mean the gross initial order (743, 924) or a mid/end-season net-of-mitigation figure (2025 saw 743→469 after resolutions). If the 2027 question is resolved using an October 31 snapshot that reflects post-mitigation-enrollment counts rather than the initial order, the effective number could be much closer to 500, and this interpretation risk is understated as "unlikely to swing below 500" without much justification given 469 rights (63%) resolved in 2025 alone. 3. Both forecasters treat the 500 threshold as a low bar given 2025-2026 history, but don't discuss whether the year-over-year trend (743→924) is likely to continue, plateau, or reverse — if settlement renewal or mitigation plan expansion follows the 2025 pattern (many districts eventually enrolling), the resolved/net figure trend is actually less monotonic than the "worsening drought" narrative implies. 4. Neither addresses that the close time (Oct 31, 2027, end of irrigation season) is after mitigation enrollment deadlines typically resolve some rights — as happened in 2025 (743 at order issuance, 469 resolved) — so the true comparison point matters a lot and wasn't rigorously pinned down before setting probabilities. 5. Both forecasts are essentially identical in structure and confidence to the market price (94%) with no independent reasoning stress-test — this is reasonable given strong base rates, but neither considers even a modest downward adjustment for the resolution-definition ambiguity, which is the single largest identified source of uncertainty in the brief itself. 6. Given the two consecutive years of overwhelming excess (743, 924) and no credible mechanism identified for a >45% single-year drop below 500, 94% may actually be too conservative rather than too aggressive — neither forecaster considers whether YES should be priced even higher (e.g., 96-97%) given the lack of any concrete evidence pointing to No.

94% (73% confidence)

Yes: 94% No: 6%

Both preceding orders (743 rights in 2025, 924 in 2026) far exceeded the 500 threshold, drought and shortfall conditions worsened into 2027, and no legal or structural changes reducing curtailment scope were identified. The critique's two counterweights roughly offset: the resolution ambiguity (gross order figure vs. post-mitigation net, given 469 of 743 resolved in 2025) and the fall 2027 settlement renewal argue for keeping meaningful No mass, while the overwhelming base-rate excess argues YES could be even higher. The question's phrasing ('listed as subject to curtailment under operative orders') most naturally captures the gross order figure, which would need a >45% single-year collapse to fall below 500 — no mechanism for that is evidenced. Staying at the Kalshi anchor of 94% YES, with ~6% on No covering the interpretation risk and an unexpectedly wet 2026-27 winter or reshaped settlement.
