Map of USGS gauge 10039500 and the river around it
Where BEAR RIVER AT BORDER, WY sits, with 3 other gauges on the same river and our water's map point.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Idaho Fish and Game uses are 66°F and 73°F.
Normal for Nov 5: 142–242 ft³/s (middle half of 89 years of record). Now: 129 ft³/s, below normal.
Below normal for this date. 129 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 89 years of record (1938–2026): 10th 115, 25th 142, median 185, 75th 242, 90th 299 ft³/s.
Daily means on record for Nov 5: lowest 35.6 ft³/s, highest 680 ft³/s.
Classes as USGS labels them (hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) ); percentiles from the USGS daily statistics (U.S. Geological Survey) (approved daily means; the reading is provisional and instantaneous).
Steady over 24 hours (+0% discharge). Rising or falling means a change of more than 10% in discharge (or 0.2 ft of gauge height) over 24 hours; our rule of thumb, not a USGS class.
Species the agency lists for Bear River: Brown Trout, Catfish, Cutthroat Trout, Mountain Whitefish, Rainbow Trout, Smallmouth Bass, Walleye.
