Davis County Water Intelligence Brief

September 7, 2026 | Free-Tier Edition

Situation Summary

Canyon creek flows in Davis County are falling through early September, and the Weber Basin system is in its typical late-season drawdown phase — WBWCD project water deliveries via the Davis Aqueduct remain the dominant supply mechanism for the county's 370,000 residents and its small remaining agricultural community. Municipal and suburban providers should note that late-season delivery reliability hinges on upstream WBWCD reservoir storage status, not on local canyon creek conditions. Reservoir storage data, 7-day forecast details, and delivery outlook analysis are available in the full brief.

Snowpack Conditions

Both SNOTEL stations monitoring the Davis County portion of the Wasatch Front show conditions typical for early September:

No percent-of-median figures are reported for either station at this date — this reflects normal seasonal conditions, as the historical median SWE for this point in the calendar is also 0.0 inches. These stations are not below normal for early September; they are at their expected end-of-season baseline. The relevant 2026 signal is not current snowpack but meltout timing: both stations melted out approximately 4–6 weeks ahead of the historical median meltout date, driven by an anomalous heat event in March. That early meltout shaped the summer streamflow trajectory but is background context at this point in the season.

Streamflow Conditions

Three USGS gauges provide the current streamflow picture for the Davis County area and the broader Weber River Basin:

Farmington Creek and Kays Creek are small Wasatch Front canyon drainages that supplement WBWCD project deliveries and serve as local snowmelt timing indicators — they are not Davis County's primary water supply. Both are reading at low late-season flows and trending downward, consistent with normal early-September conditions following an early-melt year. These creeks drain into Farmington Bay, a sub-basin of the Great Salt Lake; Davis County's water use patterns and agricultural return flows have a direct, ecologically meaningful relationship with Farmington Bay elevation.

The Weber River at Gateway (137 cfs, falling) provides broader Weber Basin context. This mainstem reading reflects the combined influence of upstream reservoir operations managed by WBWCD — the same system delivering project water to Davis County via the Davis Aqueduct.
