New Hampshire river levels: common questions

Which rivers are gauged in New Hampshire?
3 in total, listed above. The most heavily instrumented is the Saco River, with 5 gauges. A river appears under every state it runs through, so a page reached from here may cover reaches outside New Hampshire 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.
