Monongahela R at L&D4 Upper Pool at Charleroi, PA

Steady over 24 hours (gauge height +0.11 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.

No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Pennsylvania Fish and Boat Commission uses are 60°F, 70°F and 72°F.

Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
