Franklin County, ID — Water Intelligence Brief

June 15, 2026 | Bear River Basin

Situation Summary

Franklin County enters mid-June with snowpack fully melted out across all monitored SNOTEL stations in the Bear River Basin, reflecting an extremely early melt year driven by anomalous warmth earlier in the season — stations melted out approximately 4–6 weeks ahead of the historical median meltout date. Streamflow conditions across the basin are mixed, with the Bear River at Pescadero showing elevated flows while upper-basin inputs have declined, signaling a transition away from snowmelt-driven supply toward base-flow and reservoir-release-dependent conditions. Reservoir storage data, 7-day forecast details, and detailed operational recommendations are available in the full brief.

Snowpack Conditions

All eight SNOTEL stations monitored in the Bear River Basin are reporting at or near zero snow water equivalent (SWE) as of June 14, 2026:

No percent-of-median figures are reported for these stations on this date, which is consistent with normal seasonal conditions — the historical median SWE for mid-June at these elevations is also 0.0". The accurate concern for 2026 is not that snowpack is below normal *today*, but that meltout occurred approximately 4–6 weeks earlier than the historical median meltout date. The practical consequence is that the snowmelt pulse contributing to streamflow and reservoir filling concluded well ahead of schedule, compressing the recharge window and shifting the basin into a storage- and baseflow-dependent supply regime earlier in the irrigation season than typical. The trace readings at Emigrant Summit (0.1") and Giveout (0.3") are residual and inconsequential at this stage of the season.

Streamflow Conditions

Seven USGS gauges provide coverage across the Bear River Basin as of June 15, 2026:

The upper-basin picture — Bear River at Border falling to 156 cfs — confirms that snowmelt-driven inflows from Wyoming have largely concluded. The contrast with Bear River at Pescadero (1,220 cfs, rising) reflects reservoir operations and tributary contributions through the mid-basin reach; that rising trend warrants monitoring as it may reflect managed releases rather than natural runoff. Bear River near Corinne (498 cfs, rising) similarly suggests active management influence in the lower system.

Logan River (206 cfs, falling) and Little Bear River at Paradise (25 cfs, falling) are both on declining trajectories consistent with post-peak seasonal recession. Blacksmith Fork (60 cfs, stable) is holding steady, which is a modestly positive signal for that tributary's contribution.

The Malad River reading (6 cfs) carries a significant caveat: the most recent data point is from May 15, 2026 — a full month prior to this brief. That gauge should not be used for current operational decisions without verification against real-time sources.

For Franklin County irrigators, the falling trend at the upper Bear River boundary combined with the early meltout timing means that natural streamflow contributions to the system are declining and will continue to do so through the summer. Supply reliability for the remainder of the irrigation season will depend increasingly on stored water in Bear Lake and Glendale Reservoir.
