Davis County Water Intelligence Brief

August 31, 2026 | Free-Tier Edition

Situation Summary

Canyon creek flows at Farmington Creek (3 cfs, rising) and Kays Creek (10 cfs, rising) are showing late-summer upticks, while Weber River at Gateway registers 299 cfs — conditions that reflect the tail end of the irrigation season with deliveries continuing through the Davis Aqueduct from the WBWCD upstream reservoir system. Municipal providers and western bench agricultural users should plan for the final weeks of the 2026 irrigation season under a supply picture shaped by an anomalously early meltout that drew down upstream storage ahead of schedule. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Both SNOTEL stations monitoring the Davis County–adjacent Wasatch Front report effectively no remaining snowpack, consistent with normal late-August conditions at these elevations.

No percent-of-median figures are reported for either station, which indicates the historical median SWE for this date is also at or near zero — these stations are at their normal seasonal condition for late August, not anomalously below normal. The operationally significant story for 2026 is not today's snowpack reading but meltout timing: both stations melted out approximately 4–6 weeks ahead of the historical median meltout date, driven by the March heat event. That early meltout is now background context — the snowpack-driven supply pulse for 2026 has fully concluded.

Streamflow Conditions

Local canyon creeks and the Weber River mainstem provide the primary late-season flow picture for Davis County.

Farmington Creek and Kays Creek are small Wasatch Front drainages that serve as supplemental local sources and snowmelt-timing indicators — they are not Davis County's primary water supply. Their rising readings in late August may reflect recent precipitation rather than snowmelt contribution. The Weber River at Gateway at 299 cfs and rising provides the broader basin context for WBWCD system inflows, though Davis County's supply arrives via the Davis Aqueduct from upstream reservoir releases managed by WBWCD — not directly from mainstem river flow.
