River Monitoring

A variety of governmental agencies at the Federal level, as well as in Pennsylvania and West Virginia, gather data on the Monongahela River and its tributaries. The purpose of this page is to provide a consolidated set of links to that information.

Much of the information is raw data. While we may provide suggestions on the interpretation of that data, this is a "use at your own risk" area.

West Virginia Water Research Institute

The West Virginia Water Research Institute is undertaking a comprehensive water quality monitoring and reporting project for the Monongahela River. Bi-weekly samples will be collected and lab-analyzed. The resultant data will be presented a useful manner via this website utilizing a Geographic Information System database to organize and present the assembled water quality data. The project is being funded by the WV Water Research Institute and by grants from the U.S. Geological Survey, Longview Power and supporting organizations such as the West Virginia Division of Natural Resources, Allegheny Power, U.S. Army Corps of Engineers, Pennsylvania Fish & Boat Commission and others.

Navigation Reports

NOTE: You should check a river map or chart to determine which data covers your area of interest. i.e. Flooding in Morgantown is primarily determined by the stage of the Point Marion Dam, while flooding in Point Marion is primarily determined by the stage of the Grays Landing Dam. Currents at Morgantown are a function of the flow at Morgantown Dam, etc. Charts can be found here Monongahela River Navigation Charts.

Stage and Flow Data by River Basin

NOTE: Flows are typically given in cubic feet per second (cfs) passing through the gates and are not a direct measure of current speeds. Currents at most places below the dams will usually change proportionally to the flow data.

Other Information

Pennsylvania Department of Environmental Protection information:

Since October 2008 the Pennsylvania Department of Environmental Protection has been posting water quality data for the Monongahela River in Pennsylvania.

NOTE: TDS (Total Disolved Solids) is a measure of the ions (primarily sulphate, chloride, calcium and sodium) present in the water, not a measure of the particulate count.
