Juab County Water Intelligence Brief

Eastern Juab Valley Agricultural Corridor — October 26, 2026

Situation Summary

Salt Creek at Nephi is running at 5 cfs and rising, with an additional 8 cfs recorded below the Nephi Powerplant diversion — both gauges trending upward as of today, suggesting modest late-October inflow into the local system. Currant Creek near Mona reads 2 cfs and falling, signaling reduced contribution from that drainage as the season winds down. With irrigation season largely concluded for hay and alfalfa producers, current flows are more relevant to late-season stock water and any remaining field work than to active crop deliveries. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Monitoring Gap — Mount Nebo: Mount Nebo (11,928 ft), the highest peak in the Wasatch Range and the primary source of snowmelt feeding Salt Creek and Currant Creek, has no active SNOTEL station within Juab County. No in-county snowpack data is available for this brief.

No SNOTEL data was provided for this reporting period. Current SWE readings at nearby stations show 0.0" — consistent with normal seasonal conditions for late October, when snowpack has not yet accumulated meaningfully at monitoring elevations. This reflects typical pre-accumulation timing, not a below-normal condition.

For snowpack context relevant to Juab County's 2026–27 water year outlook, consult the Payson Ranger Station SNOTEL (Utah County, to the north) and the Utah Division of Water Resources seasonal assessments. The 2026 season was characterized by meltout occurring 4–6 weeks ahead of the historical median meltout date due to an anomalous March heat wave — that event is now background history as the new accumulation season begins.

Streamflow Conditions

Local Juab County gauges — primary supply indicators:

  • Salt Creek at Nephi, UT: 5 cfs, rising (10/26) — the primary supply reference for Nephi-area agriculture, reflecting direct Mount Nebo watershed runoff
  • Salt Creek below Nephi Powerplant Diversion near Nephi, UT: 8 cfs, rising (10/26) — reflects flow after powerplant diversion; the spread between the two Salt Creek readings indicates active diversion activity
  • Currant Creek near Mona, UT: 2 cfs, falling (10/26) — secondary local drainage; declining trend is consistent with late-season recession

    • Regional basin context (not local Juab County supply indicators):

  • Sevier River near Juab, UT: 0 cfs, stable (10/26) — this gauge reflects the full upstream Sevier basin (5,165 sq mi) at Yuba Lake; the zero reading reflects system storage or diversion conditions basin-wide, not local Juab County conditions
  • Sevier River near Lynndyl, UT: 30 cfs, rising (10/26) — downstream context only
  • Manti Creek below Dugway Creek, near Manti, UT: 4 cfs, stable (10/26) — adjacent Sanpete County reference
  • Sevier River at Hatch, UT: 82 cfs, rising (10/26) — upper basin reference
  • Sevier River near Kingston, UT: 116 cfs, rising (10/26) — mid-basin reference
  • Sevier River near Sigurd, UT: No recent data

    • Seasonal Guidance

  • Contact Nephi Irrigation Company to confirm end-of-season delivery schedules and verify your account status before the system transitions to winter operations.
  • Check Utah Division of Water Resources (water.utah.gov) for current Yuba Lake / Sevier Bridge Reservoir storage status, which provides regional Sevier basin context entering the winter.
  • Monitor the NRCS Utah Snow Survey (utahsnow.nrcs.usda.gov) through November for first accumulation reports at the Payson Ranger Station SNOTEL, the nearest proxy for Mount Nebo snowpack.
  • Contact Utah Division of Water Rights (waterrights.utah.gov) before any expanded groundwater pumping from the Juab Valley alluvial aquifer, which is hydraulically connected to Salt Creek and Currant Creek surface flows.

    • Subscribe for the full brief including reservoir storage, weather forecasts, depletion analysis, and detailed operational recommendations.
