Southeast Colorado alfalfa price forecasts, graded in public.

Research

Background the monthly reports stand on.

SE Colorado Hay Price Primer
What a ton of premium alfalfa costs, bale-weight math, and how quality grades map to price.
Irrigation Water in the Lower Arkansas Valley
How the Fort Lyon Canal, Fry-Ark Project, and John Martin Reservoir actually deliver (or don't deliver) water.
Snowpack & Runoff, Water Year 2026
Why 2026 is the worst water year on record for the lower Ark, and what 2002 teaches about hay prices in a drought.
Water Rights Primer
Prior appropriation, mutual ditch companies, and the compact call — the plumbing behind every price in these reports.
Pre-Registered Predictions — October 2026 Releases
Twelve predictions frozen Sep 19 for the Sep 24 / Oct 8 / Oct 22 Colorado reports, the Oct 8 ENSO discussion, the Oct 9 hay re-forecast, and the Oct 30 USDA price print. Local rows are now categorical with the base rate stated (the target prints ~2.5% of the time); state-price rows use a separate, tighter family; weekly volume is dropped.
Two Reports Compared — September 19, 2026
The corrected September report set against an independent seller report from the same data: which is better for the seller, which for the public product, and the merge that became the final report.
Correction After Independent Review — September 19, 2026
Same-day correction to the September report: a $170 Oklahoma lot left out of parity, a netback computed from an origin price, a mixed-product 'peak' claim, and holes in the calibration enforcement. What was wrong, what was fixed, the recomputed valuation.
Independent Review of the September 19 Report
A second model's review of the September 19 report against the saved primary data. Verdict: request changes. Published unedited.
Grading Record — September 2026 Releases
Rows #20–27 graded by hand against the Sep 10 Colorado report and the Sep 10 CPC discussion, every outcome tied to a quoted line; scorecard from the ledger.
Pre-Registered Predictions — September 2026 Releases
Eleven predictions frozen Aug 27 for the Sep 10 AMS/ENSO releases and the ~Sep 30 USDA price print — every range at our full calibrated width (±$65 on prices), and for the first time each numeric row records its mechanical anchor and the judgment adjustment separately, so the judgment layer itself can be graded.
Pre-Registered Predictions — Aug 12 USDA Print
Written down BEFORE the Aug 12, 2026 USDA Crop Production report, so the grading can't be fudged.
The Lessons Ledger
Every rule this project has paid for with a graded miss, newest first — binding on future reports. Bought most recently with the August 2026 production miss.
Grading Record — August 2026 Releases
Every pre-registered row graded against the actual Aug 12–13 releases, source line cited. Interval coverage 2/10 (corrected same day from 3/10 — one row was graded against the wrong metric); the economically central cluster went 0-for-3.
Independent Forecast Audit — August 2026
An outside audit of this project: the facts check out, the precision doesn't. Where we overclaim, the auditor's own confidence table, and the fixes we're adopting.
