Map of USGS gauge 12321500 and the river around it
Where BOUNDARY CREEK NR PORTHILL ID sits.
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: 33–94 ft³/s (middle half of 96 years of record). Now: 20.1 ft³/s, much below normal.
Much below normal for this date. 20.1 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 96 years of record (1931–2026): 10th 23, 25th 33, median 47, 75th 94, 90th 236 ft³/s.
Daily means on record for Nov 5: lowest 11 ft³/s, highest 423 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).
Rising over 24 hours: discharge up 12.9%, from 17.8 to 20.1 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.
Rising water. Rising over the last 24 hours (discharge up 12.9%). Keep your way back to the bank in sight and watch the level while you fish. “Rising” is our rule of thumb: more than 10% in discharge or 0.2 ft of gauge height in 24 hours, not a USGS or NWS class.
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.

The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
