Davis County Water Intelligence Brief

August 10, 2026 | Free-Tier Edition

Situation Summary

Davis County's municipal water supply is delivered via the Weber Basin Water Conservancy District (WBWCD) Davis Aqueduct, drawing from an upstream reservoir system that entered the 2026 irrigation season with accelerated drawdown following an anomalous early-spring melt event. Local canyon creeks — supplemental indicators rather than primary supply sources — are running at late-summer low flows consistent with seasonal expectations after snowpack melted out 4–6 weeks ahead of the historical median meltout date. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Both SNOTEL stations reporting for Davis County's local Wasatch Front drainages show complete melt-out as of August 9, 2026:

These readings are normal for this point in the calendar — the median SWE for both stations at this date is also 0.0", meaning current conditions are not below-normal for mid-August. The relevant 2026 signal is timing: snowpack at these elevations melted out approximately 4–6 weeks ahead of the historical median meltout date, driven by the anomalous March heat event. That earlier meltout compressed the runoff pulse into spring, reducing late-season supplemental recharge to local canyon drainages and accelerating the drawdown period for the broader WBWCD upstream storage system.

Streamflow Conditions

Three USGS gauges provide streamflow context for Davis County and the broader Weber River Basin:

Farmington Creek at 1 cfs is at a minimal late-summer flow — typical for a small Wasatch Front drainage (estimated watershed under 15 sq mi) at this point in the season, but the falling trend confirms that snowmelt contribution has fully exhausted and flows are sustained only by baseflow. Kays Creek at 6 cfs is somewhat higher, reflecting a larger drainage, though it too is trending downward. Neither creek is a primary supply source for Davis County's municipal system; both function as local supplemental sources and snowmelt-timing indicators, and their late-summer low flows are consistent with the early meltout pattern.

The Weber River at Gateway at 230 cfs and rising is the most operationally significant reading in this dataset. Gateway is an upstream Weber Basin indicator — rising flows at this location reflect conditions relevant to WBWCD system management, though the specific relationship to Davis Aqueduct delivery volumes requires direct confirmation from WBWCD. Municipal water providers should monitor WBWCD communications for any operational guidance tied to Weber River mainstem conditions.
