Map of Potomac River basin
The study area within the Potomac River basin of eastern North America. Open circles show sample site locations on streams within the C&O Canal National Historical Park. Shaded areas show physiographic regions within Maryland from west to east as the Ridge and Valley, Blue Ridge, and Piedmont, and the stippled areas show regions of karst geology.

Community index score of stream condition
Community metric index score of stream condition (mean metric decile) for 2001, 2006, 2011, and 2016. Higher values (teal shades) indicate less altered conditions while lower values indicate a higher degree of alteration (brown shades).
