Summit County Water Intelligence Brief

June 9, 2026 | Free-Tier Edition

Situation Summary

Summit County sits at the top of two major water systems — the Weber River basin, draining northwest through Echo and Rockport Reservoirs toward the WBWCD delivery system, and the Provo River basin, draining south through Kamas Valley toward Jordanelle Reservoir in Wasatch County. Both systems experienced snowpack meltout 4–6 weeks ahead of the historical median meltout date, driven by an anomalous March heat wave, meaning the county entered peak irrigation season earlier than normal with no meaningful snowpack reserve remaining. Reservoir storage data, 7-day forecast details, and depletion analysis are available in the full brief.

Snowpack Conditions

All four in-county SNOTEL stations are at or near seasonal lows consistent with complete meltout.

Weber-side (Chalk Creek drainage): The Chalk Creek station recorded 0.1" SWE with 3.0" snow depth as of June 8. The station is currently experiencing data collection issues — readings should be treated with caution and cross-checked with NRCS directly. Beaver Divide recorded 0.0" SWE and 0.0" depth, indicating complete meltout. Because no percent-of-median figure is shown for either station, the median SWE for this date is also 0.0" — both stations are at their normal seasonal condition for early June. The significant story is not today's reading but timing: meltout occurred 4–6 weeks earlier than the historical median meltout date.

Provo-side (upper Provo headwaters): Trial Lake recorded 0.8" SWE at 800% of the 0.1" median, with 3.0" snow depth — the one station showing measurable above-median snowpack. This is a localized high-elevation remnant, not a basin-wide supply signal, but it indicates some residual snowmelt contribution to the upper Provo system may continue briefly.

Streamflow Conditions

Flows across both Summit County drainages reflect a system past peak runoff and declining.

Weber basin: Weber River near Oakley recorded 290 cfs (falling) as of June 9 — this is the uppermost mainstem reading within the county. Weber River near Coalville recorded 264 cfs (stable), and Weber River at Echo recorded 328 cfs (stable), representing the integrated upper Weber flow entering the WBWCD reservoir system at Echo Reservoir. Weber River at Gateway recorded 244 cfs (falling). East Canyon Creek near Jeremy Ranch, on the Park City side of the Weber drainage, recorded just 9 cfs (falling) — a notably low reading reflecting the near-complete cessation of snowmelt contribution from that sub-drainage.

Provo basin: Provo River near Woodland recorded 204 cfs (falling) as of June 9. This gauge measures what Summit County is contributing to the Provo system before flows enter Jordanelle Reservoir in Wasatch County. At 204 cfs falling, the upper Provo is still delivering meaningful flow to downstream users, but the declining trend warrants attention as Kamas Valley irrigation demand continues through summer.
