Franklin County, ID — Water Intelligence Brief

October 26, 2026 | Bear River Basin

Situation Summary

Bear River flows are rising across the basin this week, with the Border, WY gauge reading 78 cfs and Pescadero, ID at 37 cfs — conditions consistent with late-October baseflow as the irrigation season winds down. For Franklin County producers, the operational focus has shifted from in-season delivery management to offseason planning and storage outlook heading into the 2027 season. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Mountain snowpack in the Bear River Basin is in its early accumulation phase, with most stations reporting minimal or no snow-water equivalent as of October 25.

Readings of 0.0" SWE at most stations are normal for this point in the calendar — the median SWE for late October at these elevations is also at or near zero, meaning stations are at their expected seasonal condition. USU Doc Daniel's 0% of 0.9" median reading warrants attention as the season develops. Background context: the 2026 season was defined by an anomalous March heat wave that drove meltout 4–6 weeks ahead of the historical median meltout date — a condition that affected summer supply. Early snowpack accumulation this fall will be the signal to watch heading into winter.

Streamflow Conditions

Bear River flows are broadly rising across the basin as of October 26, reflecting typical late-season and early-fall precipitation response patterns.

The widespread rising trend across mainstem and tributary gauges suggests basin-wide response to recent precipitation. The Malad River near Bear River City reading is stale (May 15 data) and should not be used for current operational decisions. Franklin County irrigators should note that late-October flows are primarily of planning interest rather than active delivery concern, as the irrigation season has largely concluded.
