water year 2026 — the snow that fed this year's pool
5 highest active SNOTEL stations in the basin (Stump Lakes, Red Mountain Pass, Taos Powderhorn, …), NRCS AWDB REST (SNOTEL), station set pinned 2026-09-17. Daily snow-water equivalent against the stations' own 30-year medians; off season the percent is withheld rather than divided by zero.

Where these numbers come from
Readings at Abiquiu Reservoir are the measuring agencies' own: each value above names its source (USGS gage, Bureau of Reclamation daily record, Army Corps project data, or this desk's committed copy) and its observation time in the reservoir's own time zone. No capacity figure ships for this reservoir until one is verified on the same basis as its storage series — so this page shows measurements, not a percent.
