Sanpete County Water Intelligence Brief

July 13, 2026 | Sevier River Basin

Situation Summary

Snowpack across Sanpete County's mountain watersheds has fully melted out, with all SNOTEL stations reading 0.0" SWE — a condition that arrived 4–6 weeks ahead of the historical median meltout date due to an anomalous March heat wave. Streamflows on Manti Creek and the Sevier River system reflect mid-summer baseflow conditions, with several gauges trending downward. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

All six SNOTEL stations serving Sanpete County's mountain watersheds are fully melted out as of July 12, 2026:

A reading of 0.0" SWE on July 12 is consistent with normal seasonal conditions for this point in the calendar — the median SWE for this date is also 0.0" at these stations. The critical signal for 2026 is not today's reading but the timing: snowpack melted out 4–6 weeks earlier than the historical median meltout date. That early departure means snowmelt-driven streamflow peaked and declined well ahead of schedule, leaving the remainder of the irrigation season dependent on stored water and whatever monsoon precipitation arrives.

Streamflow Conditions

Active USGS gauge readings as of July 13, 2026 reflect mid-summer baseflow conditions across the Sevier River system:

Manti Creek at 5 cfs and falling is the only active in-county USGS streamflow gauge for Sanpete County. No active gauge exists on the San Pitch River mainstem — a known data gap that limits real-time visibility into a portion of local agricultural water supply. The falling trend on Manti Creek is consistent with seasonal recession following early meltout.

The Sevier River near Kingston at 1 cfs and falling reflects very low mainstem flows in the upper basin. The Sevier at Lynndyl (229 cfs, falling) is substantially higher, likely reflecting reservoir operations and tributary contributions downstream — that figure represents broader basin context rather than direct Sanpete County supply. No recent data is available from the Sigurd gauge, which would otherwise provide a useful mid-basin reference point.
