Map of USGS gauge 13211205 and the river around it
Where BOISE RIVER AT CALDWELL, ID sits, with 5 other gauges on the same river and our water's map point.
Normal for Nov 5: 559–598 ft³/s (middle half of 10 years of record). Now: 520 ft³/s, below normal.
Below normal for this date. 520 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 10 years of record (2017–2026): 10th 503, 25th 559, median 584, 75th 598, 90th 636 ft³/s.
Daily means on record for Nov 5: lowest 497 ft³/s, highest 640 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 (+2.2% 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.
Under 66°F. Water 53.1°F now; the highest in the last 24 hours was 53.6°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)This gauge is on our page for Boise River, but no agency page we read lists its species.
Cold water. Water 53.1°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.
Turn Around Don't Drown (National Weather Service)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
NWS observed 6.41 ft stage, 516 ft³/s at Nov 5, 7:45 PM MST (NWS gauge CDWI1; its stage datum can differ from the USGS gauge height).
NWS has not set flood categories for this gauge.
Graphical forecasts are not available during times of high water, forecast crest information can be found in the local WFO web page.
