Juab County Water Intelligence Brief

Eastern Juab Valley Agricultural Water Conditions | June 15, 2026

Situation Summary

Salt Creek is running at 6 cfs as of June 15, reflecting stable Mount Nebo melt contributions to local Nephi-area irrigators, while the 2026 water year is defined by an anomalous March heat wave that drove snowpack meltout across the region 4–6 weeks ahead of the historical median meltout date. Local hay, alfalfa, and cattle operations should treat active irrigation season as well underway with no additional snowmelt recharge expected from Mount Nebo. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Mount Nebo and Local Watershed Status

Mount Nebo (11,928 ft), the highest peak in the Wasatch Range, sits directly above eastern Juab County and provides the primary snowmelt source feeding Salt Creek and Currant Creek. However, Juab County has no active SNOTEL station — there is no in-county snowpack monitoring on or near Mount Nebo. This is a meaningful data gap for local irrigators.

The 2026 regional signal is clear: an anomalous March heat wave accelerated snowmelt across the Mountain West, and snowpack stations throughout the broader Wasatch and Sevier River headwaters melted out approximately 4–6 weeks ahead of the historical median meltout date. For Mount Nebo and the Salt Creek watershed, this means the annual snowmelt pulse almost certainly peaked and passed well before its typical late-May to early-June window. As of mid-June, no meaningful snowpack recharge to Salt Creek or Currant Creek should be anticipated.

For the most current snowpack assessment relevant to Mount Nebo, local irrigators should consult:

The practical takeaway: the snowmelt-driven portion of the 2026 irrigation season is effectively complete for the Salt Creek watershed. Available water is now a function of what is stored locally and what baseflow Salt Creek sustains through the summer.

Streamflow Conditions

Local Juab County Indicators

Salt Creek at Nephi, UT — 6 cfs, stable (June 15). This is the primary supply indicator for Nephi-area irrigators. The stable reading indicates that active snowmelt pulses have passed and Salt Creek has settled into summer baseflow conditions. Nephi Irrigation Company and local ditch operators should plan deliveries around this stable but modest flow rate.

Salt Creek below Nephi Powerplant Diversion, near Nephi, UT — 6 cfs, stable (June 15). The matching reading at this downstream gauge indicates that the powerplant diversion is currently not significantly altering the flow regime between the two measurement points, or that flows are balanced across the diversion. Local irrigators drawing below the powerplant should note parity with the upper gauge.

Currant Creek near Mona, UT — 1 cfs, rising (June 15). Currant Creek is contributing minimal flow to the local system. The rising trend is noteworthy but from a very low base — this small uptick may reflect local soil moisture drainage or minor late-season tributary input rather than significant additional supply. Do not plan for meaningful additional delivery from Currant Creek under current conditions.

Regional Basin Context (not local supply indicators)

Sevier River near Juab, UT — 313 cfs, rising (June 15). This gauge at Yuba Lake reflects the entire upstream Sevier River basin (approximately 5,165 square miles of drainage). It is a regional basin indicator, not a Juab County agricultural supply indicator. The rising trend reflects upstream basin-wide conditions. For Yuba Lake / Sevier Bridge Reservoir storage status, contact the Utah Division of Water Resources.

Sevier River near Lynndyl, UT — 123 cfs, falling (June 15). Downstream of Yuba Lake; reflects reservoir operations and release patterns. Not a local Juab supply reference.

Manti Creek below Dugway Creek, near Manti, UT — 11 cfs, falling (June 15). Located in adjacent Sanpete County; provides context for conditions in the broader Sevier headwaters upstream of Juab County.
