Juab County Water Intelligence Brief

Eastern Juab Valley Agricultural Corridor — October 19, 2026

Situation Summary

Salt Creek at Nephi is running at 4–5 cfs and falling, signaling the expected end-of-season decline in local supply across the Nephi, Mona, and Levan corridor. With the 2026 irrigation season effectively closing, hay growers and ranchers should finalize any remaining delivery needs now, as flows will continue to taper through late October. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

No SNOTEL stations are active 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 dedicated in-county snowpack monitoring. This is a known data gap for local irrigators.

All SNOTEL stations across the region currently show 0.0" snow water equivalent — consistent with normal mid-October conditions, when the historical median SWE is also 0.0". This is not a below-normal signal; it reflects the routine pre-accumulation period before winter snowpack begins to build. The relevant 2026 context is timing: snowpack across the broader region melted out 4–6 weeks ahead of the historical median meltout date, which compressed the spring and early-summer runoff window for Salt Creek.

For current Mount Nebo snowpack assessment as the season transitions, consult the Payson Ranger Station SNOTEL (Utah County, immediately north of Juab County) and the Utah Division of Water Resources seasonal outlook reports.

Streamflow Conditions

Salt Creek at Nephi (primary local indicator): 4 cfs, falling. This is the direct supply signal for Nephi-area irrigators and reflects Mount Nebo watershed runoff conditions.

Salt Creek below Nephi Powerplant Diversion near Nephi: 5 cfs, falling. The slightly higher reading downstream of the powerplant diversion reflects combined local contributions; both readings confirm the late-season declining trend.

Currant Creek near Mona: 2 cfs, falling. This secondary local source is at minimal late-season flow, consistent with normal October drawdown.

For regional basin context only: the Sevier River near Juab (gauge 10219000) reads 0 cfs. This gauge reflects the full upstream Sevier basin at Yuba Lake and is not a Juab County supply indicator — it reflects system-wide conditions across the entire 5,165-square-mile Sevier drainage, not local Salt Creek or Currant Creek conditions.
