Potomac Basin Water Quality Data Inventory

Interstate Commission on the Potomac River Basin

Five people standing in a stream looking at a net used for stream monitoring.Water quality managers, researchers, and decision-makers depend on available water quality data, but it can be a challenge just to find the data collected for a specific waterway. To this end, ICPRB staff members produced an inventory of available water quality data sources in the Potomac River basin that includes information on watershed characteristics such as land use, zoning, elevation, and precipitation to help explain water quality patterns seen in the data.

Data Inventory

The following products have been developed as part of the data inventory effort:

  • Interactive Tool (Please note that the tool may take a few moments to load)—users can use an interactive tool that provides access to existing water quality monitoring efforts in the Potomac River basin.
  • Project Report (2014) —provides a summary of the inventory, a description of data sources and how to obtain data, an identification of gaps in the inventory, and a discussion of next steps.


Efforts are made by ICPRB to keep this information up-to-date. As water quality data inventory collection efforts in the basin are extensive, however, the information provided here is for informational purposes only and is not guaranteed to be complete or appropriate for any particular use.
