Davis County Water Intelligence Brief

Weber River Basin | September 14, 2026 | Free-Tier Edition

Situation Summary

Weber Basin Water Conservancy District project water deliveries via the Davis Aqueduct remain the dominant supply mechanism for Davis County's approximately 370,000 residents, with late-season flows on local canyon creeks and the Weber River mainstem providing supplemental indicators of system-wide conditions. Kays Creek is rising and the Weber River at Gateway is holding steady at 151 cfs, suggesting the broader basin has not yet entered critical low-flow territory for this point in the season. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Both SNOTEL stations monitoring Davis County's Wasatch Front drainages are reporting end-of-season conditions consistent with full seasonal meltout.

No percent-of-median figures are reported for either station, which indicates that the historical median SWE for this date is also 0.0" — both stations are at their normal seasonal condition for mid-September. These readings do not indicate below-normal snowpack for this point in the calendar. As background context: the 2026 season was defined by an anomalous March heat wave that drove meltout approximately 4–6 weeks ahead of the historical median meltout date across the region, shifting the seasonal supply pulse earlier than typical.

Streamflow Conditions

Three USGS gauges provide current flow data across the Weber River Basin relevant to Davis County water management.

Farmington Creek is running at 2 cfs — a modest but stable late-season reading for this local Wasatch Front drainage. Kays Creek at 6 cfs and rising is notable for mid-September; a rising signal at this point in the season may reflect recent precipitation or localized drainage response rather than snowmelt contribution. The Weber River at Gateway holding at 151 cfs stable is the most operationally significant reading: the mainstem is not in acute decline at present. Canyon creek flows on Farmington Creek and Kays Creek are supplemental local sources and seasonal indicators — they are not Davis County's primary supply. Municipal providers and suburban water systems should continue to track WBWCD Davis Aqueduct delivery status as the primary operational variable.
