New Jersey river levels: common questions

Is any river flooding in New Jersey right now?

No gauge in the state is above flood stage. No gauge is above action stage either.

Which rivers are gauged in New Jersey?

3 in total, listed above. The most heavily instrumented is the Delaware River, with 20 gauges. A river appears under every state it runs through, so a page reached from here may cover reaches outside New Jersey as well.

What is the difference between flood stage and action stage?

Action stage is the level at which the Weather Service starts paying attention and agencies begin preparing. Flood stage is the level at which water starts affecting property or roads at that specific location. Both are set per gauge by the local Weather Service office, which is why two gauges on the same river can have very different numbers.
