Steady over 24 hours (+5% 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.

• 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.
