Map of USGS gauge 13190500 and the river around it
Where SF BOISE RIVER AT ANDERSON RANCH DAM ID sits, with 2 other gauges on the same river and our water's map point.
Under 66°F. Water 51.4°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.”
Normal for Nov 5: 284–320 ft³/s (middle half of 83 years of record). Now: 304 ft³/s, normal.
Normal for this date. 304 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 83 years of record (1944–2026): 10th 199, 25th 284, median 303, 75th 320, 90th 613 ft³/s.
Daily means on record for Nov 5: lowest 1.2 ft³/s, highest 1,540 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.

Cold water. Water 51.4°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.

NWS observed 3.1 ft³/s at Nov 5, 7:15 PM MST (NWS gauge ANDI1; its stage datum can differ from the USGS gauge height).
NWS has not set flood categories for this gauge.
