Summit County, UT — Water Intelligence Brief

August 3, 2026 | Free Tier

Situation Summary

Summit County sits at the top of two major river systems simultaneously: the Weber River, flowing northwest through Echo and Rockport Reservoirs toward the WBWCD delivery network, and the Provo River, flowing south through Kamas Valley toward Jordanelle Reservoir in Wasatch County. In 2026, all four in-county SNOTEL stations melted out 4–6 weeks ahead of the historical median meltout date, meaning the seasonal snowpack contribution to both systems concluded earlier than normal — a condition that now shapes late-summer streamflow across both watersheds. Reservoir storage data for Echo, Rockport, and East Canyon Reservoirs, along with 7-day forecast details, are available in the full brief.

Snowpack Conditions

All four in-county SNOTEL stations are reporting 0.0" snow water equivalent and 0.0" snow depth as of August 2, 2026. This is the expected seasonal condition for early August — the historical median SWE for these stations on this date is also 0.0", so current readings do not indicate a below-normal snowpack today. The meaningful signal for 2026 is timing: meltout occurred 4–6 weeks earlier than the historical median meltout date across all four stations.

Weber-side (upper Chalk Creek drainage):

These two stations monitor the Weber River headwaters above Coalville. The early meltout means snowmelt-driven recharge to Echo and Rockport Reservoirs concluded well ahead of schedule, with peak inflows arriving earlier in the season than the WBWCD system would typically expect.

Provo-side (upper Provo River headwaters):

Trial Lake and Beaver Divide are Summit County's home stations for the Provo watershed — they monitor the snowpack that becomes the Provo River flow measured at Woodland and ultimately delivered toward Jordanelle. Their early meltout is the primary upstream driver of current Kamas Valley streamflow conditions.

Streamflow Conditions

Summit County's six active USGS gauges span both watersheds and reflect the post-melt, late-summer baseflow regime now underway.
