Davis County Water Intelligence Brief

June 29, 2026 | Free-Tier Edition

Situation Summary

Davis County's municipal water supply enters peak summer demand backed by Weber Basin Water Conservancy District (WBWCD) project water delivered via the Davis Aqueduct from an upstream reservoir system including Pineview, Echo, Rockport, Lost Creek, and East Canyon. The 2026 season is defined not by low snowpack today, but by an anomalous March heat event that drove snowmelt 4–6 weeks ahead of the historical median meltout date across the Weber Basin, compressing the natural recharge window for that upstream system. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Both SNOTEL stations monitoring the Wasatch Front above Davis County have reached complete seasonal meltout, consistent with the early-melt character of 2026.

Both stations show effectively zero snow-water equivalent for this date. Importantly, the historical median SWE for late June at these elevations is also 0.0" — so current readings do not indicate below-normal conditions *today*. The meaningful signal is timing: meltout occurred 4–6 weeks ahead of the historical median meltout date, meaning the seasonal snowmelt pulse that recharges canyon creeks and contributes to upstream reservoir inflows concluded well before its typical window. No additional snowmelt contribution to local streamflow or WBWCD reservoir inflows should be anticipated.

Streamflow Conditions

Canyon creek flows serve as supplemental local sources and snowmelt timing indicators for Davis County. Primary municipal supply arrives via the Davis Aqueduct — canyon creek conditions do not define Davis County's supply posture, but they provide useful context for system state.

All three gauges are currently trending upward. Kays Creek at 27 cfs and Farmington Creek at 4 cfs represent active flow in the local Wasatch Front drainages, providing modest supplemental delivery context for the late-June period. The Weber River at Gateway (258 cfs, rising) reflects broader Weber Basin mainstem conditions upstream of the WBWCD diversion infrastructure that feeds the Davis Aqueduct system. Rising conditions across all gauges warrant monitoring but do not indicate flood or diversion concern at this stage. Given the early meltout, late-June rising flows may reflect localized precipitation or system variability rather than sustained snowmelt.
