Weber County Water Intelligence Brief

September 28, 2026 | Free Tier

Situation Summary

Flows on the Ogden River below Pineview Reservoir are running at just 8 cfs and falling, signaling that late-season releases are tapering as the 2026 irrigation season winds down — Ogden Valley dairy operators, hay growers, and cattle farms should plan for continued delivery tightening through season's end. The Weber River at Ogden reads 35 cfs (falling), confirming basin-wide recession across the full Weber system. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Both SNOTEL stations in the Weber County area are at their normal end-of-season condition for late September:

  • Ben Lomond Peak (09/27): SWE 0.2", snow depth 0.0"
  • Ben Lomond Trail (09/27): SWE 0.3", snow depth 1.0"

    • No percent-of-median figures are shown for either station, which is expected — the historical median SWE for these stations at this date is also at or near 0.0", so current readings reflect normal seasonal drawdown, not an anomalous deficit. The accurate 2026 story is timing: Ben Lomond Peak was among the most stressed stations in Utah this water year, running 13 inches below normal at peak SWE, and both stations melted out 4–6 weeks ahead of the historical median meltout date following an anomalous March heat wave. That early meltout is the reason basin flows have been on a prolonged declining trajectory throughout summer and into fall.

    Streamflow Conditions

    All active gauges in the Weber basin show falling conditions:

  • Ogden River below Pineview Reservoir (09/27): 8 cfs, falling — this is the critical delivery gauge for Ogden Valley irrigators; at 8 cfs, available supply for dairy operations, alfalfa, and hay fields is extremely limited
  • Weber River at Gateway (09/28): 118 cfs, falling — upper mainstem indicator reflecting upstream basin recession
  • Weber River at Ogden (09/28): 35 cfs, falling — the basin integrator gauge capturing total system flow after upstream diversions and reservoir releases; falling conditions here confirm system-wide late-season decline

    • The divergence between Gateway (118 cfs) and Ogden (35 cfs) reflects diversions and consumptive use along the mainstem corridor. Weber River inflow is a significant contributor to Great Salt Lake elevation; continued low-flow conditions through fall reduce GSL inflows during a period when every acre-foot matters environmentally.

    Seasonal Guidance

  • Contact Weber Basin Water Conservancy District (WBWCD, Ogden) to check current Pineview Reservoir storage status and projected Ogden River release schedule through end-of-season.
  • Reach out to the Ogden River Water Users Association for delivery scheduling and any end-of-season curtailment notices affecting Ogden Valley agricultural users.
  • Check with Utah Division of Water Rights (waterrights.utah.gov) before any changes to groundwater pumping from the Weber Valley basin-fill aquifer, as pumping is hydraulically connected to senior Ogden and Weber River surface rights.
  • Western benchland alfalfa growers in Pleasant View, Farr West, and Harrisville should contact their local canal company or WBWCD to confirm remaining delivery windows before the season closes.
