Juab County Water Intelligence Brief

Eastern Juab Valley Agricultural Corridor | August 17, 2026

Situation Summary

Salt Creek is running at 3 cfs as of August 17 — a low but stable late-season flow consistent with typical August conditions in the Nephi/Mona agricultural corridor, though the 2026 season was shaped by an anomalous March heat wave that drove snowmelt across the Wasatch 4–6 weeks ahead of the historical median meltout date, effectively shortening the runoff window for local irrigators. Currant Creek near Mona is reading 0 cfs and falling, indicating that supplemental flow from that drainage has ceased for the season. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Juab County has no active in-county SNOTEL station. 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 snowpack monitoring instrumentation on or near its summit. This is a genuine monitoring gap for local irrigators.

No SNOTEL data was returned for Juab County stations in this reporting period. For the current date of August 17, an absence of reported snow water equivalent (SWE) is seasonally normal — median SWE at nearby mountain stations is also at or near 0.0" by mid-August under typical conditions. The meaningful signal for 2026 is not today's SWE reading, but meltout timing: snowpack across the broader Wasatch melted out approximately 4–6 weeks ahead of the historical median meltout date, driven by the anomalous March heat event. That early meltout is the primary reason late-season streamflows are at the low end of the range entering the critical August irrigation window.

Local irrigators should consult the Payson R.S. SNOTEL station (Utah County, to the north of Mount Nebo) for the nearest available snowpack reference, and the Utah Division of Water Resources for seasonal snowpack assessments relevant to the Salt Creek watershed.

Streamflow Conditions

Salt Creek at Nephi, UT is the primary supply indicator for the eastern Juab Valley corridor.

Salt Creek is holding at 3 cfs at both gauge points, though the below-powerplant reading is trending falling, suggesting modest continued decline. Currant Creek has effectively ceased surface flow for the season. At these levels, available surface water supply for Juab Valley irrigators is at the low end of late-season norms. Hay growers and alfalfa producers completing final cuttings should plan around the current 3 cfs Salt Creek reading as the baseline available supply.
