Rising over 24 hours: gauge height up 1.03 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.

• Above NWS action stage. Above action stage: high, fast water. Don't wade.

  Flood categories: action stage, minor, moderate and major flooding (National Weather Service)

• Rising water. Rising over the last 24 hours (gauge height up 1.03 ft). 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.
