Map of USGS gauge 13074400 and the river around it
Where Portneuf R. at Inkom, ID sits, with 5 other gauges on the same river and our water's map point.
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.
USGS publishes no daily statistics for this gauge, so the reading is not compared with the record.
Steady over 24 hours (−2.9% 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.
Species the agency lists for Portneuf River: Brown Trout, Cutthroat Trout, Rainbow Trout.

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.
