Merrimack River: water levels along the river

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

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.
