Davis County Water Intelligence Brief

October 12, 2026 | Weber River Basin | Free-Tier Edition

Situation Summary

Streamflows across Davis County's Wasatch Front drainages are rising this week, with Farmington Creek at 10 cfs and Kays Creek at 72 cfs — conditions consistent with mid-October precipitation response rather than snowmelt contribution. Weber Basin Water Conservancy District project water deliveries via the Davis Aqueduct remain the county's primary supply mechanism; suburban providers should contact WBWCD directly for current system delivery status as the county transitions into the low-demand shoulder season. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Both SNOTEL stations in the Davis County monitoring network are reporting conditions typical for mid-October:

The depth/SWE relationship at Farmington Lower — showing 2.0 inches of depth with 0.0 inches of SWE — indicates very low-density early-season precipitation, likely a light dusting that has not yet consolidated into measurable water equivalent. Neither station shows a percent-of-median figure, meaning the median SWE for this date is also effectively 0.0 inches; both stations are at normal seasonal condition for mid-October, not below normal.

For context, 2026 was marked by an anomalous March heat wave that drove meltout 4–6 weeks ahead of the historical median meltout date across the Weber Basin — a factor that shaped spring and early-summer supply conditions. That seasonal pattern is now background history. Meaningful snowpack accumulation for the 2027 water year is not expected to begin until November at the earliest.

Streamflow Conditions

Three USGS gauges provide current flow data relevant to Davis County's supply picture:

Farmington Creek at 10 cfs is within the range expected for a small Wasatch Front drainage in mid-October. As a watershed of limited area, Farmington Creek responds quickly to precipitation events; its rising status likely reflects recent rainfall rather than snowmelt. It functions as a supplemental local source and a snowmelt timing indicator — not Davis County's primary supply driver.

Kays Creek at 72 cfs is notably elevated for a canyon creek of its size and warrants attention. The rising trend, concurrent with Farmington Creek's rise, suggests a basin-wide precipitation response. Municipal providers and the Davis & Weber Counties Canal Company should note that such pulses are typically short-duration in October.

The Weber River at Gateway at 130 cfs and rising provides the broader basin context. This mainstem reading reflects combined upstream contributions and informs WBWCD's operational picture for Davis Aqueduct deliveries. Contact WBWCD for current project water delivery status.

Davis County's canyon creek flows and agricultural return flows drain into Farmington Bay, a sub-basin of the Great Salt Lake. County water use and return flow patterns carry ecological relevance for Farmington Bay elevation — a consideration relevant to both municipal and agricultural operators.
