Summit County, UT — Water Intelligence Brief

July 13, 2026 | Free-Tier Edition

Situation Summary

Summit County sits at the headwaters of two major river systems — the Weber River flowing north and west through Echo and Rockport Reservoirs into the broader WBWCD network, and the upper Provo River flowing south toward Jordanelle Reservoir in Wasatch County — making it the source county for water that sustains communities and agriculture well beyond its borders. All four in-county SNOTEL stations have recorded 0.0" snow water equivalent, consistent with normal mid-July seasonal conditions, but the 2026 season was defined by an anomalous March heat wave that drove meltout 4–6 weeks ahead of the historical median meltout date, compressing the runoff window earlier in the spring. Reservoir storage data for Echo Reservoir, Rockport Reservoir, and East Canyon Reservoir, along with 7-day forecast details, are available in the full brief.

Snowpack Conditions

All four Summit County SNOTEL stations are reporting 0.0" snow water equivalent and 0.0" snow depth as of July 12, 2026 — consistent with normal bare-ground conditions for mid-July at these elevations. No below-normal language is warranted based on today's readings alone.

Weber-side stations (upper Chalk Creek drainage):

These stations monitor snowpack in the upper Weber River headwaters above Coalville. Both reached bare ground ahead of schedule this season.

Provo-side stations (upper Provo River headwaters):

Trial Lake and Beaver Divide are in-county stations monitoring the upper Provo River drainage — the snowpack that feeds the Kamas Valley agricultural corridor and ultimately Jordanelle Reservoir. Both are at their expected mid-July seasonal baseline.

The critical 2026 signal is not today's readings but timing: all four stations melted out 4–6 weeks ahead of the historical median meltout date. That earlier-than-normal meltout means the season's snowmelt contribution to streamflow and reservoir storage was concentrated into a shorter, earlier window than downstream operators and irrigators typically plan around.

Streamflow Conditions

Summit County's gauges reflect what is leaving the county toward both downstream reservoir systems — the defining hydrologic role of a headwaters county.
