Potomac River: water levels along the river

We have 9 gauges on the Potomac River. Every gauge with a normal range is reading within it.

The gauges on this page are spread across Maryland, West Virginia and District of Columbia. 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.
