Sanpete County Water Intelligence Brief

October 26, 2026 | Sevier River Basin


Situation Summary

Streamflows across the Sevier River Basin are stable to rising this week, with the Sevier River showing upward movement at multiple gauges and Manti Creek holding steady at modest late-October levels — conditions consistent with seasonal transition into the dormant period as irrigation demand winds down. Turkey producers, ranchers, and hay operations should note that late-season delivery reliability is the operative question heading into winter, not immediate supply stress. Reservoir storage data and 7-day forecast details are available in the full brief.


Snowpack Conditions

All six SNOTEL stations in and around Sanpete County are reporting at or near zero snow water equivalent, which is normal for this point on the calendar — median SWE for late October at these elevations is also effectively zero, so current readings reflect seasonal conditions, not a deficit.

Station readings as of October 25, 2026:

  • Beaver Dams: 0.0" SWE, 0.0" depth
  • GBRC HQ: 0.0" SWE, 1.0" depth
  • GBRC Meadows: 0.0" SWE, 0.0" depth
  • Mammoth-Cottonwood: 0.1" SWE, 0.0" depth
  • Mt Baldy: 0.5" SWE, 0.0" depth
  • Thistle Flat: 0.1" SWE, 0.0" depth
  • Early-season snowpack accumulation is just beginning at the higher elevations, with Mt. Baldy showing the most meaningful reading at 0.5" SWE. The 2026 water year context: snowpack across the region melted out approximately 4–6 weeks ahead of the historical median meltout date following an anomalous March heat wave, which shaped summer streamflow conditions. That event is now background history. The forward-looking question is how robustly accumulation builds through November and December — a metric to watch as the season progresses.


    Streamflow Conditions

    Manti Creek below Dugway Creek near Manti (the only active in-county USGS gauge) is reading 4 cfs and stable as of October 26. This is a modest but steady late-season flow consistent with the dormant season transition. No active USGS gauge exists on the San Pitch River mainstem — that remains a known monitoring gap. Contact Sanpete Water Conservancy District for any supplemental local monitoring data.

    Sevier River gauges in adjacent counties provide broader basin context:

  • Sevier River at Hatch: 82 cfs, rising
  • Sevier River near Kingston: 116 cfs, rising
  • Sevier River near Lynndyl: 30 cfs, rising
  • Sevier River near Sigurd: No recent flow data available
  • The rising trend at Hatch, Kingston, and Lynndyl is a notable signal for this time of year. Basin-wide streamflow is moving upward across all reporting gauges, which may reflect recent precipitation or regional runoff — causal attribution is beyond the scope of this brief. The Sigurd gauge data gap limits visibility into the mid-basin reach most directly relevant to Sanpete County delivery infrastructure; users dependent on that reach should contact their water district for current operational status.


    Seasonal Guidance

  • Contact Sanpete Water Conservancy District to check current delivery system status and any end-of-season carryover or storage updates relevant to your operation.
  • Check Gunnison Reservoir and Piute Reservoir operational status through local irrigation companies and the Utah State Engineer's Office (waterrights.utah.gov) for current storage figures heading into winter.
  • Monitor NRCS Utah SNOTEL (nrcs.usda.gov/utah) through November and December for early accumulation signals at Mt. Baldy and other high-elevation stations — early-season snowpack trajectory will shape next spring's supply outlook.
  • Contact Utah Division of Water Rights (waterrights.utah.gov) for any water rights administration questions, including end-of-season accounting and planning for the 2027 irrigation season.

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