Map of USGS gauge 13037500 and the river around it
Where SNAKE RIVER NR HEISE ID sits, with 5 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: 1,680–3,290 ft³/s (middle half of 116 years of record). Now: 1,560 ft³/s, below normal.
Below normal for this date. 1,560 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 116 years of record (1911–2026): 10th 1,420, 25th 1,680, median 2,740, 75th 3,290, 90th 4,090 ft³/s.
Daily means on record for Nov 5: lowest 567 ft³/s, highest 5,350 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 (−1.3% 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 South Fork of the Snake River: Brown Trout, Cutthroat Trout, Mountain Whitefish, Rainbow Trout, Cutbow - Cutthroat x Rainbow Trout.
