Weber County Water Intelligence Brief

October 5, 2026 | Free-Tier Edition

Situation Summary

Ogden River flows below Pineview Reservoir are running at 10 cfs and rising as of October 5, signaling that end-of-season releases are sustaining minimal late-season deliveries to Ogden Valley irrigators — but with irrigation demand winding down for dairy hay and alfalfa operations, the operational question now shifts to how the system closes out the 2026 water year. Weber River flows at Ogden (102 cfs, falling) reflect declining mainstem supply as the basin transitions out of the active irrigation season. Reservoir storage trajectory through Pineview and the upstream system is the defining variable for how Weber Basin enters the 2026–2027 carry-over period — reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Both SNOTEL stations reporting for Weber County show 0.0" snow water equivalent and 0.0" snow depth as of October 4, 2026 — conditions that are normal for this date, as the historical median SWE at these elevations is also 0.0" in early October. The absence of snowpack at Ben Lomond Peak and Ben Lomond Trail is not a current anomaly; it reflects typical seasonal meltout timing at this point in the calendar.

The 2026 water year context, however, is significant: Ben Lomond Peak melted out approximately 4–6 weeks ahead of the historical median meltout date, driven by an anomalous March heat wave. That early meltout compressed the spring runoff window and reduced the total volume delivered into Pineview and the broader Weber Basin reservoir system during the critical April–June fill period.

New snowpack accumulation at these stations — which would signal the start of the 2026–2027 snowpack season — has not yet begun as of this report date.

Streamflow Conditions

Ogden River Below Pineview Reservoir (nr Huntsville): 10 cfs, rising. This is the critical delivery gauge for Ogden Valley irrigators. A rising signal at 10 cfs in early October suggests ongoing but minimal managed releases from Pineview. Ogden Valley dairy, hay, and pasture operations should coordinate directly with the Ogden River Water Users Association regarding any remaining delivery commitments and end-of-season schedule.

Weber River at Gateway: 89 cfs, falling. This upstream Weber mainstem reading reflects declining natural and managed inflows as runoff season concludes.

Weber River at Ogden: 102 cfs, falling. As the basin integrator gauge, this reading captures total system flow after upstream diversions and reservoir contributions. The falling trend at both Weber River gauges confirms the basin is in seasonal recession — consistent with normal October hydrology, though the 2026 water year's early meltout means less residual storage buffer than typical entering this period.

*Note: The Weber River is a major inflow source for the Great Salt Lake. Late-season flow volumes at the Weber at Ogden gauge contribute to GSL elevation — a relevant environmental consideration as basin managers evaluate end-of-year operations.*
