Weber County Water Intelligence Brief

September 7, 2026 | Free-Tier Edition

Situation Summary

Ogden River flows below Pineview Reservoir are running at 304 cfs and rising as of this morning, providing active late-season supply to Ogden Valley dairy, hay, and alfalfa operations — a stronger-than-expected pulse for early September. Meanwhile, the Weber River mainstem is declining: 137 cfs at Gateway and 34 cfs at Ogden reflect the expected late-season taper as upstream system inputs diminish. Pineview Reservoir's release schedule remains the controlling variable for Ogden Valley irrigators this week — contact Weber Basin Water Conservancy District and the Ogden River Water Users Association for current gate operations and anticipated delivery windows. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Both SNOTEL stations reporting for Weber County show nominal residual snowpack as of September 6, consistent with normal conditions for this point in the water year:

At this date on the calendar, the historical median SWE at both stations is also effectively 0.0" — meaning current readings reflect normal seasonal conditions, not a below-normal anomaly. The critical 2026 snowpack story is one of timing, not current depth: Ben Lomond Peak was approximately 13 inches below normal at peak SWE earlier this water year, and both stations melted out 4–6 weeks ahead of the historical median meltout date following an anomalous March heat event. That early meltout is now background context. Its operational consequence — accelerated runoff that front-loaded streamflow into spring while compressing late-season reservoir recharge — is what irrigators are managing through now.

Streamflow Conditions

Three active USGS gauges provide current basin coverage:

The Ogden River reading is the most operationally significant figure for Ogden Valley irrigators. At 304 cfs and rising, Pineview releases are delivering meaningful flow to valley hay and dairy operations this week — above what would typically be expected at this point in a stressed water year. Whether this reflects active reservoir management or residual system drainage warrants direct confirmation with the Ogden River Water Users Association.

The Weber mainstem tells a different story: falling conditions at both Gateway (137 cfs) and Ogden (34 cfs) reflect the normal late-season decline. The Weber at Ogden gauge functions as the basin integrator — capturing total mainstem flow after upstream diversions and reservoir contributions. Its continued decline signals tightening supply for western benchland users in Pleasant View, Farr West, and Harrisville, where remaining alfalfa acreage faces the most exposure to late-season curtailment pressure. Note that Weber River flows are among the inflows sustaining Great Salt Lake elevation — continued late-season consumption efficiency matters beyond the farm gate.
