Port Tobacco River
In 1998, the Maryland Clean Water Action Plan identified the Port Tobacco River watershed as one of the State’s waterbodies that did not meet water quality requirements. In response
to this finding, the Maryland Department of the Environment (MDE) and Charles County formed a
partnership to develop a Watershed Restoration Action Strategy (WRAS) for the Port Tobacco River watershed. The following Stream Corridor Assessment (SCA) survey is part of the WRAS development process.
The SCA survey provides descriptive and positional data for potential environmental problems
along a watershed’s non-tidal stream network. Developed by the Maryland Department of
Natural Resources (DNR) Watershed Services, the survey is a watershed management tool to
identify environmental problems and prioritize restoration opportunities on a watershed basis.
As part of the survey, trained personnel walk a watershed’s streams and record data and locations
for environmental problems that can be easily observed within the stream corridor. Each
potential problem site is ranked on a scale of one to five for its severity, correctability, and
access for restoration work.
