Juab County Water Intelligence Brief

Eastern Juab Valley Agricultural Corridor | August 10, 2026

Situation Summary

Salt Creek and Currant Creek are both running at low late-season levels, consistent with an early-melt year in which Mount Nebo snowpack melted out 4–6 weeks ahead of the historical median meltout date — meaning the seasonal snowmelt pulse that feeds local diversions concluded earlier than normal and available surface supply is now limited to residual baseflow. Local irrigators in the Nephi, Mona, Levan, and Mills corridor should plan around continued declining stream conditions through the remainder of the irrigation season. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Mount Nebo and the Monitoring Gap

Mount Nebo (11,928 ft), the highest peak in the Wasatch Range, sits directly above eastern Juab County and provides the primary snowmelt recharge for Salt Creek and Currant Creek. However, Juab County has no active SNOTEL station on or near Mount Nebo — this is a genuine monitoring gap. No in-county snowpack data is available for this brief.

At this point in the calendar — mid-August — SNOTEL stations across the region read 0.0" snow water equivalent (SWE), which reflects normal seasonal conditions for this date, not an anomalous deficit. The accurate concern for 2026 is meltout timing: the anomalous March heat wave caused Mount Nebo's snowpack to melt out approximately 4–6 weeks ahead of the historical median meltout date. That early departure means the snowmelt-driven runoff window closed well before mid-July rather than extending into late July or early August as in typical years. The seasonal water that would normally have supported late-summer diversion is already gone.

Local irrigators should contact the Utah Division of Water Resources for seasonal snowpack assessments and consult SNOTEL data from the Payson Ranger Station (Utah County, to the north) as the nearest proxy indicator for Mount Nebo watershed conditions.

Streamflow Conditions

Salt Creek — Primary Local Indicator

Salt Creek is the primary water supply reference for Nephi-area agriculture. Both gauges show very low flows in a falling trend, indicating that snowmelt contribution from the Mount Nebo watershed has effectively ended and streamflow is tracking toward minimum late-season baseflow. Available diversion supply for local hay and alfalfa irrigators is limited and declining.

Currant Creek — Secondary Local Indicator

Currant Creek is similarly running at minimal baseflow levels with a falling trend — consistent with the early-melt seasonal picture across the local watershed.

Regional Sevier Basin Context

The Juab gauge reflects conditions across the full upstream Sevier River basin (over 5,000 square miles) entering Yuba Lake — it is a regional basin indicator, not a Juab County supply indicator. Local irrigators should not interpret this flow as available local supply.
