Wasatch County Water Intelligence Brief

October 26, 2026 | Provo River Basin

Situation Summary

Provo River flows are stable to rising across Heber Valley this week, with the Charleston gauge reading 157 cfs and the Hailstone gauge climbing to 242 cfs, signaling active late-October runoff contribution in the upper basin. For Heber Valley irrigators, the irrigation season is effectively closed — these flows reflect off-season channel conditions, not delivery demand — but the trajectory is relevant for reservoir fill heading into winter. Park City-area municipal users on the Wasatch side should continue monitoring Jordanelle operations as the system transitions into its winter storage accumulation period. Reservoir storage data and detailed operational context are available in the full brief.

Snowpack Conditions

Important disclosure: The three SNOTEL stations physically located within Wasatch County — Currant Creek, Daniels-Strawberry, and White River #1 — drain eastward to the Duchesne River and ultimately the Colorado River basin. They do not monitor snowpack that contributes to the Provo River system or Heber Valley water supply, and are excluded from this brief. Primary Provo River basin snowpack indicators are Trial Lake (Summit County, reporting since 1978) and Beaver Divide (Summit County, reporting since 1978). Wolf Creek Peak is located in Wasatch County and drains to the Provo River basin, but carries a short record — reporting only since August 2020, less than six years — and should be interpreted with that limitation in mind.

Current readings as of October 25, 2026:

Trial Lake is the one station showing a percent-of-median figure: 0% of a 0.7" median. A trace median this early in the season reflects the fact that measurable snowpack at this elevation in late October is not yet typical — the station is not dramatically below normal for this calendar date. Wolf Creek Peak's 1.0" of snow depth with 0.0" SWE suggests a very light, low-density snow layer with negligible water content. Beaver Divide shows no accumulation at this time.

Background context: the 2026 water year was defined by an anomalous March heat wave that drove snowmelt 4–6 weeks ahead of the historical median meltout date across the Mountain West. That event shaped the summer supply picture. As of late October, the basin is in the early accumulation window, and current SWE readings represent normal seasonal conditions for this point in the calendar — not a deficit signal. The critical variable going forward is whether November and December deliver above-normal accumulation to offset the compressed 2026 melt season.

Streamflow Conditions

Three active USGS gauges monitor the Provo River mainstem through Wasatch County as of October 26, 2026:

Flows increase from the upper Heber Valley reach (River Road Bridge) downstream through Charleston and into the Hailstone gauge near Jordanelle Reservoir, consistent with tributary contributions along the corridor. The rising signal at Hailstone is the most operationally significant reading this week — it indicates inflow to the Jordanelle pool is increasing, which is relevant for both USBR reservoir operations and Park City-side municipal system planning. The stable readings at River Road Bridge and Charleston suggest the upper basin is not experiencing unusual runoff pulses at this time. For Heber Valley agricultural users, these flows are well within the off-season range and do not require active irrigation management response.

Consult official sources including your local water district, U.S. Bureau of Reclamation Upper Colorado Region (administers Deer Creek, Jordanelle, and Strawberry Reservoir operations as part of the Provo River Project and Central Utah Project Bonneville Unit), and the Utah Division of Water Rights for regulatory decisions and water rights administration. Strawberry Reservoir (Bonneville Unit, Central Utah Project) is an inter-basin transfer facility that diverts water eastward from the Strawberry River — which would naturally drain to the Duchesne River and Colorado River basin — westward across the Wasatch divide into the Provo River system; users should monitor USBR announcements regarding Bonneville Unit operations, including Colorado River Compact implications.
