Bear Lake County, ID — Water Intelligence Brief

August 17, 2026 | Bear River Basin

Situation Summary

Bear Lake County enters the final weeks of the 2026 irrigation season with snowpack fully melted out across all monitored SNOTEL stations — a condition that arrived 4–6 weeks ahead of the historical median meltout date, compressing this year's snowmelt-driven streamflow pulse earlier in the season. Bear River flows at key downstream gauges remain in a moderate range for mid-August, though the earlier-than-normal meltout means late-season buffer from snowmelt is effectively exhausted. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

All eight SNOTEL stations monitoring the Bear River Basin show complete or near-complete melt as of August 16, 2026:

At this point in the calendar, a median SWE of 0.0" is expected at these elevations — stations reading 0.0" are at their normal seasonal condition for mid-August, not below normal. The notable signal for 2026 is timing: these stations melted out 4–6 weeks ahead of the historical median meltout date, driven by the anomalous March heat wave. Small residual readings at Emigrant Summit (0.2") and Giveout (0.3") and a 1.0" snow depth at Franklin Basin reflect trace amounts or instrument-level anomalies and do not represent meaningful seasonal storage. No snowpack contribution to streamflow should be anticipated for the remainder of the irrigation season.

Streamflow Conditions

Seven USGS gauges provide current flow data across the Bear River Basin:

The Bear River at Pescadero — the most directly relevant gauge for Bear Lake County agricultural users — is reading 805 cfs and falling, consistent with late-season drawdown following the early meltout. The substantial spread between the upper watershed gauge at Border, WY (67 cfs) and Pescadero (805 cfs) reflects reservoir management operations, tributary inputs, and storage releases along the system rather than direct snowmelt contribution. The Malad River near Bear River City reading of 6 cfs is outdated (last updated 05/15) and should not be used for current planning purposes. Stable readings on the Blacksmith Fork, Little Bear River, and Logan River suggest baseflow conditions have largely stabilized on those tributaries. With no snowpack remaining and flows generally on a falling or stable trend, irrigators should not anticipate additional late-season flow increases absent significant precipitation events.
