Juab County Water Intelligence Brief

Eastern Juab Valley Agricultural Corridor — September 14, 2026

Situation Summary

Salt Creek at Nephi is running at 2 cfs and falling, signaling that the local irrigation season is in its final stage — hay growers and alfalfa producers in the Nephi, Mona, and Levan corridor should plan accordingly for end-of-season delivery availability. Currant Creek near Mona shows 0 cfs with a rising trend, offering no meaningful supplemental supply at this time. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

No active SNOTEL stations are operating within Juab County. Mount Nebo (11,928 ft), the highest peak in the Wasatch Range and the primary snowmelt source for Salt Creek and Currant Creek, has no in-county snowpack monitoring. Irrigators should consult the Payson Ranger Station SNOTEL site in neighboring Utah County to the north for the nearest proxy reading.

For the 2026 season, the broader regional signal is timing rather than current depth: mountain snowpack across the Wasatch melted out approximately 4–6 weeks ahead of the historical median meltout date, driven by an anomalous March heat wave. At this point in mid-September, all stations — including any Mount Nebo snowfield — are at their normal seasonal condition of zero snow water equivalent. The early meltout is background context for why late-season streamflows are limited; it is not an active current condition. Contact the Utah Division of Water Resources for seasonal snowpack assessment records relevant to the Salt Creek watershed.

Streamflow Conditions

Salt Creek at Nephi (primary local indicator): 2 cfs, falling (09/13). This gauge directly reflects Mount Nebo melt and Salt Creek watershed runoff available to Nephi-area irrigators. At 2 cfs and declining, deliveries are at minimum late-season levels.

Salt Creek Below Nephi Powerplant Diversion near Nephi: 2 cfs, falling (09/13). Consistent with the upstream reading, confirming limited flow through the local delivery reach.

Currant Creek near Mona: 0 cfs, rising (09/14). No meaningful flow contribution at present; the rising trend is noted but does not represent a reliable supply signal at this volume.

The Sevier River near Juab (60 cfs, rising) reflects conditions across the full upstream Sevier basin — a 5,000-plus square mile drainage — and is not a Juab County supply indicator. It is relevant as regional basin context near Yuba Lake, which sits at the Juab/Sanpete county line and serves the broader Sevier system. For Yuba Lake storage status, contact the Utah Division of Water Resources.
