Merrimack River: water levels along the river

We have 7 gauges on the Merrimack River. 1 of them reads above normal for the date, and none is low.

The gauges on this page are spread across New Hampshire and Massachusetts. Reading the gauges in order shows how a rise or a dry spell travels downstream, usually over a day or more on a big river. Fall is often a low point for rivers after the summer, until steady rain returns.
