Summit County, UT — Water Intelligence Brief

July 20, 2026 | Free-Tier Edition

Situation Summary

Summit County sits at the headwaters of two major Utah river systems — the Weber River flowing northwest through Echo and Rockport Reservoirs toward Ogden, and the Provo River flowing south through Kamas Valley toward Jordanelle Reservoir in Wasatch County. What happens in Summit County's snowpack and streams determines what Weber County, Davis County, and Wasatch County receive downstream. In 2026, all four in-county SNOTEL stations melted out 4–6 weeks ahead of their historical median meltout dates, compressing the runoff window and shifting peak supply earlier than the downstream reservoir system typically expects. 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 reporting 0.0" snow water equivalent (SWE) and 0.0" snow depth as of July 19, 2026 — a normal seasonal condition for mid-July, when the historical median SWE at each station is also 0.0". The hydrological concern for 2026 is not today's reading but the timing of this season's meltout.

Weber Basin headwaters (Chalk Creek drainage):

These two stations are the primary snowpack monitors for the upper Weber River corridor feeding into the WBWCD reservoir system at Echo Reservoir. Both melted out 4–6 weeks ahead of the historical median meltout date, meaning the Weber system's snowmelt pulse arrived and passed earlier than normal.

Provo Basin headwaters (upper Provo River):

Trial Lake and Beaver Divide are in-county stations monitoring the upper Provo River headwaters above Kamas Valley. Like the Chalk Creek stations, both reflect an early-melt season — the snowmelt contribution to the upper Provo River concluded ahead of schedule, with implications for summer baseflow in the Kamas/Woodland corridor.
