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.
Map of USGS gauge 01401750 and the river around it
Where Millstone River at Griggstown NJ sits, with 3 other gauges on the same river.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. New Jersey Fish and Wildlife publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a New Jersey rule, with New Jersey Fish and Wildlife's own figure added: 68°F and 72°F.
Steady over 24 hours (gauge height +0.01 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.
