Sanpete County Water Intelligence Brief

June 22, 2026 | Sevier River Basin

Situation Summary

Snowpack across Sanpete County's contributing watersheds has fully melted out, with all SNOTEL stations reading 0.0" SWE as of June 21 — conditions consistent with the seasonal norm for this date, but arriving 4–6 weeks ahead of the historical median meltout date due to an anomalous March heat wave across the Mountain West. Streamflow in the local Manti Creek system is low and falling, while broader Sevier River Basin gauge readings are mixed. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

All six SNOTEL stations reporting in Sanpete County's contributing watersheds show 0.0" snow water equivalent (SWE) and 0.0" snow depth as of June 21, 2026:

  • Beaver Dams: SWE 0.0", Depth 0.0"
  • GBRC HQ: SWE 0.0", Depth 0.0"
  • GBRC Meadows: SWE 0.0", Depth 0.0"
  • Mammoth-Cottonwood: SWE 0.0", Depth 0.0"
  • Mt. Baldy: SWE 0.0", Depth 0.0"
  • Thistle Flat: SWE N/A, Depth 0.0"

    • These readings reflect normal seasonal conditions for late June — the historical median SWE for these stations at this point in the calendar is also 0.0". The meaningful signal is not current SWE deficit but meltout timing: the snowpack that feeds summer streamflow and reservoir storage melted out 4–6 weeks earlier than the historical median meltout date. That early departure means the peak snowmelt pulse has already passed, and no additional snowpack-driven recharge to streams or reservoirs should be anticipated for the remainder of the summer season.

    Streamflow Conditions

    In-County:

  • Manti Creek below Dugway Creek, near Manti (10215900): 9 cfs, falling (June 22). Manti Creek is the only active USGS streamflow gauge within Sanpete County and serves as the primary in-county indicator. At 9 cfs and on a falling trend, flows are in the low range for mid-June and declining as snowmelt contributions diminish. No active gauge exists on the San Pitch River mainstem — that remains a known data gap for local monitoring.

    • Sevier River Basin Context:

  • Sevier River at Hatch, UT: 62 cfs, rising (June 22). This upper-basin gauge reflects conditions in the headwaters zone upstream of Sanpete County's influence area.
  • Sevier River near Kingston, UT: 3 cfs, falling (June 22). Very low flow in this mid-basin reach, with a falling trend.
  • Sevier River near Lynndyl, UT: 483 cfs, rising (June 22). This lower-basin gauge reflects aggregated system flows including reservoir operations and diversions well downstream of Sanpete County.
  • Sevier River near Sigurd, UT: No recent flow data available.

    • The combination of falling flows at Manti Creek and Kingston, the absence of data at Sigurd, and the early meltout timing collectively indicate that snowmelt-driven flow contributions are winding down across the basin. The rising reading at Lynndyl likely reflects reservoir operational releases or timing effects rather than natural snowmelt input at this stage of the season.

    Seasonal Guidance

  • Contact the Sanpete Water Conservancy District to check current delivery schedules and any updates to local canal and reservoir operational status for the remainder of the irrigation season.
  • Contact the Utah Division of Water Rights (waterrights.utah.gov) to verify your water right priority and confirm current administrative conditions on the Sevier River system before adjusting diversion volumes.
  • Check with the Sevier River Water Users Association regarding current Piute Reservoir storage status and projected delivery allocations for Sanpete County users served via the Sevier Valley–Piute Canal.
  • Contact Utah Division of Water Resources for current storage data on Yuba Lake (Sevier Bridge Reservoir) and Gunnison Reservoir, as downstream and local storage levels are the primary remaining supply buffer for the season.

    • Subscribe for the full brief including reservoir storage, weather forecasts, depletion analysis, and detailed operational recommendations.
