Box Elder County Water Intelligence Brief

Bear River Basin | September 7, 2026 | Free-Tier Edition

Situation Summary

Bear River flows through Box Elder County are falling, with the near-Corinne gauge reading 239 cfs on a declining trend, signaling tightening late-season supply for canal company diversions across the Tremonton area and surrounding agricultural lands. Irrigators dependent on Bear River Canal Company and direct Bear River diversions should monitor delivery schedules closely as flows continue to recede heading into the final weeks of the irrigation season. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

All SNOTEL stations monitoring the Bear River Basin watersheds above Box Elder County show snowpack conditions consistent with normal seasonal meltout for early September. No actionable snowpack-derived inflow should be expected from the mountains at this point in the calendar year.

Station readings as of September 6, 2026:

The trace readings at Emigrant Summit (0.2" SWE) and Giveout (0.4" SWE) represent minimal early-season accumulation or instrument artifacts and carry no meaningful supply implication. Stations showing depth values with 0.0" SWE reflect residual soil or ground conditions, not snow water. As background context, the 2026 season was characterized by meltout occurring 4–6 weeks ahead of the historical median meltout date across the Bear River Basin — a factor that shaped this season's streamflow timing.

Streamflow Conditions

Bear River flows are falling at the key agricultural delivery gauges serving Box Elder County. The mainstem picture shows a clear declining trajectory from the Wyoming border through the lower valley.

Gauge readings as of September 7, 2026:

The 239 cfs reading at Corinne is the most operationally relevant figure for Box Elder County irrigators — it reflects what is available in the lower Bear River for direct diversions and canal company deliveries. The falling trend at both the Border and Corinne gauges indicates continued flow decline without near-term relief from upstream inflow. The Pescadero reading of 775 cfs reflects upstream Idaho conditions and suggests Bear River Commission and canal company managers should monitor how much of that flow reaches lower-river users after losses and diversions through the system. Tributary gauges on the Blacksmith Fork, Little Bear River, and Logan River are holding stable, offering some modest buffer for Cache Valley contributions entering the lower system. The Malad River near Bear River City is reporting only a May 15 reading — current conditions at that location are unknown and should be confirmed directly with USGS or local water managers.
