USGS keeps no flow statistics at this gauge, so there is no normal range for flow; the chart shows gauge height as USGS publishes it.

No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Nevada Department of Wildlife uses are 65°F.
Species list not on file for this gauge. Check the Nevada Department of Wildlife: Nevada fishing and stocking reports · Nevada fishing rules and regulations.
Falling over 24 hours: gauge height down 0.26 ft. 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.
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.
