Boise River is a freestone river in Idaho.
Pick one of its USGS gauges and hear from us when the flow moves into or out of its usual range for the date, or crosses a flow you set. We check the public USGS reading every 2 hours and email only when it crosses, at most once every 6 hours. Flow alone is not a fishing forecast or a safety call.
Signed in: one step. Otherwise we email a confirmation link first. Every alert has one-click links to stop it.
Start from the agency's public access map. Nothing on this page grants or implies access: check the agency map, posted signs and landowner permission before you fish.

Normal for Nov 5: 348–460 ft³/s (middle half of 115 years of record). Now: 334 ft³/s, below normal.
Below normal for this date. 334 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 115 years of record (1912–2026): 10th 309, 25th 348, median 407, 75th 460, 90th 586 ft³/s.
Daily means on record for Nov 5: lowest 260 ft³/s, highest 1,080 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 (−2.3% 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.
NWS observed 5.33 ft stage, 334 ft³/s at Nov 5, 4:30 PM MST (NWS gauge BTSI1; its stage datum can differ from the USGS gauge height).
NWS has not set flood categories for this gauge.

Normal for Nov 5: 200–273 ft³/s (middle half of 44 years of record). Now: 239 ft³/s, normal.
Normal for this date. 239 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 44 years of record (1983–2026): 10th 170, 25th 200, median 258, 75th 273, 90th 295 ft³/s.
Daily means on record for Nov 5: lowest 105 ft³/s, highest 1,380 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 (+1.7% 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.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 3.2 ft³/s at Nov 5, 3:45 PM MST (NWS gauge BIGI1; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 8:41 AM MST. Highest point: 3.3 ft³/s on Nov 15, 5:00 AM MST (Below NWS action stage).

USGS publishes no daily statistics for this gauge, so the reading is not compared with the record.
Steady over 24 hours (+1.1% 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.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
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.
This gauge is on our page for Boise River, but no agency page we read lists its species.
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.

Much below normal for this date. 502 ft³/s is below the 10th percentile 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.

Under 66°F. Water 53.6°F now; the highest in the last 24 hours was 54.1°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 53.6°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.”
