Massachusetts river levels: common questions

Is any river flooding in Massachusetts right now?

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

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.
