Davis County Water Intelligence Brief

October 26, 2026 | Free-Tier Edition

Situation Summary

Canyon creek flows in Davis County are rising this week — Farmington Creek at 4 cfs and Kays Creek at 6 cfs — reflecting early autumn precipitation rather than any meaningful snowmelt contribution, while WBWCD project water deliveries via the Davis Aqueduct remain the county's primary supply backstop as the 2026 irrigation season winds down. For the small remaining agricultural community on the western bench, this late-October period typically marks the transition to post-irrigation dormancy, and current conditions do not indicate any immediate delivery emergency. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Farmington SNOTEL (10/25): Snow water equivalent (SWE) 0.2 inches; snow depth 0.0 inches.

Farmington Lower SNOTEL: Data collection issues; no reading available.

At this point in the calendar, trace or zero SWE at Wasatch Front SNOTEL stations is the expected seasonal condition — the historical median SWE for late October at these elevations is also effectively 0.0 inches, so current readings do not indicate a below-normal snowpack anomaly for this date. The meaningful 2026 snowpack story is one of timing: the spring snowpack melted out approximately 4–6 weeks ahead of the historical median meltout date, driven by an anomalous March heat wave. That early meltout shaped reservoir filling and WBWCD project water availability through the summer and fall. Snowpack accumulation season is now beginning; conditions through November and December will establish the early trajectory for water year 2027.

Streamflow Conditions

Farmington Creek above Diversion near Farmington: 4 cfs, rising (10/26).

Kays Creek near Layton: 6 cfs, rising (10/26).

Weber River at Gateway: 53 cfs, stable (10/26).

Both Farmington Creek and Kays Creek are posting rising flows consistent with recent autumn precipitation, not snowmelt. These small Wasatch Front drainages — each draining roughly 4–15 square miles — serve as local hydrologic indicators and supplemental sources, but they are not Davis County's primary water supply. WBWCD deliveries via the Davis Aqueduct provide the county's foundational municipal supply, independent of local canyon creek conditions. The Weber River at Gateway, at 53 cfs and stable, reflects late-season baseflow on the mainstem — a reasonable late-October condition that provides context for the broader Weber Basin system feeding WBWCD's upstream reservoir network. Return flows from Davis County's canyon creeks and agricultural lands drain into Farmington Bay, a sub-basin of the Great Salt Lake; late-season flow conditions in these drainages carry ecological relevance beyond local water supply.
