Map of USGS gauge 12322000 and the river around it
Where KOOTENAI RIVER AT PORTHILL ID sits, with 3 other gauges on the same river and our water's map point.
Normal for Nov 5: 5,470–10,800 ft³/s (middle half of 13 years of record). Now: 7,500 ft³/s, normal.
Normal for this date. 7,500 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 13 years of record (2014–2026): 10th 4,910, 25th 5,470, median 7,370, 75th 10,800, 90th 12,000 ft³/s.
Daily means on record for Nov 5: lowest 4,690 ft³/s, highest 12,100 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).
Falling over 24 hours: discharge down 34.8%, from 11,500 to 7,500 ft³/s. 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.
Under 66°F. Water 50°F now; the highest in the last 24 hours was 50.2°F. In the study Idaho Fish and Game cites, trout landed in water under 66°F survived best: mortality “was 69% higher for trout landed at 73°F water temperatures than for those landed when waters were less than 66°F.” In summer, “early-mornings are typically best while the water is still cool.”
Perspective: Trout fishing during low water and high temperatures (25 July 2024; archived copy) (Idaho Department of Fish and Game) The heat is on, but trout and other coldwater fish have been around the block a time or two (9 Aug 2022; archived copy) (Idaho Department of Fish and Game)Species the agency lists for Kootenai River: Bluegill / Pumpkinseed / Sunfish, Cutthroat Trout, Largemouth Bass, Mountain Whitefish, Rainbow Trout.

Cold water. Water 50°F. NWS: “Cold shock can be just as severe and dangerous from water temperatures of 50-60°F (10-15°C) as it is from water at 35°F (2°C).” “Always wear a life jacket in and around the water.”
Cold Water Hazards and Safety (National Weather Service)Turn Around Don't Drown. “A mere 6 inches of fast-moving flood water can knock over an adult.” No flow number makes a crossing safe; if in doubt, stay out.
