No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. Florida Fish and Wildlife Conservation Commission publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Florida rule: 68°F.

Rising over 24 hours: discharge up 804.5%, from 4.19 to 37.9 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 805%). 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.

Water clarity: Turbidity measures the relative clarity of water: higher means murkier. No agency publishes a fishing threshold for it; compare with this gauge's own recent readings.
