Juab County Water Intelligence Brief

Eastern Juab Valley Agricultural Corridor — Nephi / Mona / Levan / Mills

*July 20, 2026*

Situation Summary

Salt Creek is running at 4 cfs and falling — a low midsummer flow that reflects the primary challenge for eastern Juab Valley irrigators this season. Snowpack across the Mountain West melted out 4–6 weeks ahead of the historical median meltout date, meaning the Mount Nebo watershed delivered its runoff pulse earlier in the season than typical, and that early supply is now behind you. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Juab County has no active SNOTEL station on or near Mount Nebo. This is a meaningful monitoring gap. Mount Nebo (11,928 ft), the highest peak in the Wasatch Range, sits directly above the eastern Juab Valley and provides the primary snowmelt that feeds both Salt Creek and Currant Creek — the two water sources that matter most to local irrigators. Because no in-county SNOTEL data exists, there are no station readings to report for Juab County today.

For seasonal snowpack context, local irrigators should consult the Payson Ranger Station SNOTEL site (Utah County, to the north) and the Utah Division of Water Resources seasonal assessments, which cover the Mount Nebo massif as part of their broader Wasatch Range reporting. What is known for 2026: an anomalous March heat wave drove meltout across the Mountain West 4–6 weeks ahead of the historical median. That early meltout signal is consistent with the falling flows now observed on Salt Creek — the snowmelt contribution to local streams is effectively exhausted for the season.

Streamflow Conditions

Salt Creek at Nephi, UT — 4 cfs (falling) is the primary supply indicator for eastern Juab Valley agriculture. A falling trend at 4 cfs in mid-July signals that the seasonal snowmelt pulse has passed and flows are declining toward late-summer baseflow. Local irrigators drawing from Salt Creek should treat current deliveries as the operational ceiling for the near term.

Salt Creek Below Nephi Powerplant Diversion, near Nephi — 5 cfs (stable) reflects conditions immediately below the powerplant diversion point. The slight difference between the two Salt Creek readings is consistent with normal diversion and return-flow dynamics in this reach.

Currant Creek near Mona — 1 cfs (rising) is a secondary local indicator. At 1 cfs, Currant Creek is at minimal flow. The rising trend is a modest positive signal but does not indicate significant supply availability at this level.

Sevier River near Juab — 242 cfs (stable) reflects the full Sevier River system upstream of Yuba Lake, draining approximately 5,165 square miles of basin. This gauge is a regional basin indicator, not a Juab County supply gauge — local irrigators drawing from Salt Creek and Currant Creek are not served by this flow. It is noted here for regional context only.

Additional Sevier basin gauges for broader context: Manti Creek below Dugway Creek, near Manti — 5 cfs (stable); Sevier River near Lynndyl — 244 cfs (stable); Sevier River at Hatch — 56 cfs (rising); Sevier River near Kingston — 9 cfs (rising); Sevier River near Sigurd — no recent data available.
