Monongahela R: water levels along the river

We have 4 gauges on the Monongahela R. 2 of them read above normal for the date, and none is low.

The gauges are in Pennsylvania. 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.
