Davis County Water Intelligence Brief

September 21, 2026 | Free-Tier Edition

Situation Summary

Weber Basin Water Conservancy District project water deliveries via the Davis Aqueduct continue to sustain municipal and residential supply across Davis County's urbanized communities, while local canyon creek flows — including Kays Creek and Farmington Creek — are showing modest rising signals for mid-September. Supply conditions reflect a late-season transition typical for this point in the calendar, with upstream reservoir status via WBWCD remaining the operative variable for providers heading into fall. Reservoir storage data, 7-day forecast details, and WBWCD system delivery outlook are available in the full brief.

Snowpack Conditions

Both active SNOTEL stations in the Davis County area are reporting end-of-season conditions consistent with normal September meltout:

No percent-of-median figures are reported for either station, which reflects the expected condition: the historical median SWE for this date is also 0.0 inches at both locations. These readings indicate normal seasonal meltout status — not below-normal snowpack relative to this point in the calendar.

As background context: the 2026 water year was defined by an anomalous March heat wave that drove meltout across the Wasatch Front 4–6 weeks ahead of the historical median meltout date. That early-season event shaped summer supply — it is past context, not current operational news.

Streamflow Conditions

Three USGS gauges provide current flow data relevant to Davis County:

Farmington Creek and Kays Creek are small Wasatch Front drainages serving as supplemental local sources and snowmelt-timing indicators — they are not Davis County's primary supply mechanism. The rising signals on both local creeks are a modest late-season indicator but should not be interpreted as materially affecting municipal supply reliability, which depends on WBWCD Davis Aqueduct deliveries from the upstream reservoir system.

The Weber River at Gateway reads 134 cfs on a falling trend, reflecting normal late-season recession. Weber River mainstem conditions feed directly into WBWCD's upstream storage and delivery operations — providers should monitor WBWCD communications for any operational adjustments tied to mainstem flow trajectory.
