Water Intelligence Brief — Box Elder County, UT

July 20, 2026 | Bear River Basin | Free-Tier Edition

Situation Summary

Box Elder County enters the peak irrigation demand window of mid-July with no meaningful snowpack remaining in the Bear River Basin — all SNOTEL stations melted out 4–6 weeks ahead of their historical median meltout dates, reflecting the anomalous March heat event that characterized the 2026 water year across the Mountain West. Streamflows on the Bear River near Corinne are modest and falling, signaling that canal companies drawing from direct Bear River diversions should plan around continued seasonal decline through August. Reservoir storage data, 7-day precipitation forecasts, and detailed operational recommendations for Bear Lake and Cutler Reservoir are available in the full brief.

Snowpack Conditions

All eight SNOTEL stations reporting within the Bear River Basin show zero or negligible snow water equivalent (SWE) as of July 19, 2026 — a normal condition for this calendar date, as the historical median SWE at all of these stations is also 0.0" by mid-July. The meaningful story for 2026 is not the current reading but the timing: these stations melted out 4–6 weeks earlier than the historical median meltout date, driven by the anomalous March heat wave. That early meltout exhausted the snowpack-driven runoff pulse well before peak summer demand, leaving streamflows now entirely dependent on groundwater baseflow contributions and any monsoon precipitation.

Station-by-station readings (July 19, 2026):

No additional snowmelt-driven streamflow contributions should be anticipated from the basin headwaters for the remainder of the irrigation season.

Streamflow Conditions

Bear River Basin streamflows present a mixed but generally declining picture across the system as of July 20, 2026. The most directly relevant gauge for Box Elder County agricultural users is the Bear River near Corinne, UT, which recorded 158 cfs and falling — the primary indicator of water available for direct diversion by Bear River Canal Company and other lower-valley canal users. A falling trend at this gauge during peak July demand is an important planning signal.

The Bear River at Border, WY — the upstream entry point to the system — recorded 68 cfs and falling, indicating that inflows from the upper basin continue to decline. The contrast between the Border gauge (68 cfs) and the Pescadero, ID gauge (1,390 cfs, stable) reflects the significant regulatory and storage management activity occurring mid-system in Idaho, including operations associated with Bear Lake and intervening diversions, before flows reach Utah.

Tributary gauges provide supporting context:

The tributary gauges on Blacksmith Fork, Logan River, and Little Bear River are stable but at modest levels consistent with late-season baseflow conditions. The Malad River near Bear River City reading is dated May 15 and should not be used for current planning without an updated reading from USGS. Box Elder County agricultural users dependent on direct Bear River diversions should note the falling trend at Corinne and adjust expectations for available flow through August accordingly.
