Sanpete County Water Intelligence Brief

August 3, 2026 | Sevier River Basin

Situation Summary

Snowpack across Sanpete County's contributing terrain has fully melted, with all six SNOTEL stations reading 0.0" SWE — consistent with normal seasonal conditions for early August, though the 2026 season was notable for snowpack melting out 4–6 weeks ahead of the historical median meltout date. Streamflow on Manti Creek and the Sevier River system is falling or flat, signaling the basin has transitioned fully into late-season irrigation mode with no remaining snowmelt recharge. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

All six SNOTEL stations monitoring Sanpete County's contributing terrain are reporting 0.0" snow water equivalent and 0.0" snow depth as of August 2, 2026. This is the expected seasonal condition for this point in the calendar — median SWE for these stations in early August is also 0.0", so current readings reflect normal late-summer status rather than a below-normal deficit.

Station readings:

The key seasonal signal for 2026 is not today's snowpack reading but meltout timing: these stations melted out 4–6 weeks ahead of the historical median meltout date, meaning the pulse of snowmelt runoff that typically supports streamflows into June and July arrived and was exhausted significantly earlier this season. There is no remaining snowpack contribution to streamflow, and none should be expected.

Streamflow Conditions

Manti Creek below Dugway Creek near Manti (the only active in-county USGS gauge) is running at 5 cfs with a falling trend as of July 31. This is the primary in-county streamflow indicator for Sanpete County agriculture. No active gauge exists on the San Pitch River mainstem — that remains a known data gap; contact Sanpete Water Conservancy District for additional local monitoring context.

Sevier River gauges in adjacent counties provide broader basin context:

The falling trend at Hatch and Kingston, combined with the absence of data at Sigurd, limits visibility into mid-basin conditions. The Lynndyl reading of 229 cfs stable is the most downstream available indicator and reflects cumulative basin contributions including reservoir releases and tributary inputs upstream. The contrast between very low flows at Kingston (4 cfs) and the higher Lynndyl reading underscores the importance of upstream storage operations in sustaining downstream supply at this point in the season.
