Sanpete County Water Intelligence Brief

August 24, 2026 | Sevier River Basin | Free-Tier Edition

Situation Summary

Sanpete County enters the final stretch of the 2026 irrigation season with snowpack fully melted across all monitored SNOTEL stations — consistent with an anomalous early-melt year in which mountain snowpack melted out 4–6 weeks ahead of the historical median meltout date. Streamflow on the Sevier River system is mixed, with some gauges stable and others falling, signaling tightening late-season supply conditions for hay, alfalfa, and livestock operations. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

All six SNOTEL stations reporting for the Sanpete County area recorded 0.0" snow water equivalent (SWE) and 0.0" snow depth as of August 23, 2026:

  • Beaver Dams: 0.0" SWE / 0.0" depth
  • GBRC HQ: 0.0" SWE / 0.0" depth
  • GBRC Meadows: 0.0" SWE / 0.0" depth
  • Mammoth-Cottonwood: 0.0" SWE / 0.0" depth
  • Mt Baldy: 0.0" SWE / 0.0" depth
  • Thistle Flat: 0.0" SWE / 0.0" depth

    • Zero SWE in late August is normal for this point in the calendar — the historical median SWE for these stations at this date is also 0.0". The concern 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 mountain snowmelt pulse that typically sustains late-season streamflow arrived and passed substantially earlier than usual. No snowmelt-driven streamflow contribution to the Sevier River system should be expected for the remainder of the irrigation season.

    Streamflow Conditions

    Streamflow across the Sevier River Basin is showing a divided picture as of August 24, 2026:

  • Manti Creek Below Dugway Creek, near Manti: 3 cfs (stable) — This is the only active in-county USGS gauge for Sanpete County and serves as the primary in-county streamflow indicator. At 3 cfs, flows are modest. No active gauge exists on the San Pitch River mainstem, representing a known data gap for county-level monitoring.
  • Sevier River at Hatch: 44 cfs (stable) — Stable flow at the upper Sevier provides some consistency at the basin's headwaters.
  • Sevier River near Kingston: 6 cfs (falling) — A falling trend at Kingston is notable; this mid-basin gauge suggests decreasing supply moving downstream from the upper reaches.
  • Sevier River near Lynndyl: 323 cfs (rising) — The Lynndyl reading is substantially higher and rising, which may reflect return flows, reservoir releases, or tributary contributions downstream of Sanpete County. Users should not interpret this gauge as indicative of upper-basin supply conditions.
  • Sevier River near Sigurd: No recent flow data available.

    • The combination of falling flows at Kingston, modest in-county flows on Manti Creek, and the absence of any remaining snowmelt input points to tightening surface water availability for the balance of the season. Turkey producers, ranchers, and hay growers dependent on surface diversions should monitor local delivery conditions closely. Contact Sanpete Water Conservancy District for additional local monitoring context beyond what USGS gauges capture.

    Seasonal Guidance

  • Contact Sanpete Water Conservancy District to check current local delivery status and whether any operational adjustments have been made for late-season conditions.
  • Contact the Utah Division of Water Rights (waterrights.utah.gov) to verify current water right priority and confirm your standing under the Sevier River Basin priority system before making any late-season operational decisions.
  • Check with the Sevier River Water Users Association regarding current Piute Reservoir operational status and delivery outlook for Sanpete County users served by the Sevier Valley–Piute Canal.
  • Contact the Utah Division of Water Resources for current status of Yuba Lake / Sevier Bridge Reservoir, the downstream regional storage facility at the Juab/Sanpete county line.
