Stream Corridor Assessment (SCA) in the Anacostia Watershed

The Stream Corridor Assessment (SCA) survey was developed by Maryland DNR's Watershed Restoration Division as a tool to help environmental managers identify environmental problems and prioritize restoration opportunities on a watershed basis. As part of the survey, trained personnel walk the watershed's entire stream network and record information on a variety of environmental problems that can be easily observed within the stream corridor. Common environmental problems documented in the survey include: eroding stream banks, inadequate stream buffers, exposed pipes, altered stream channels, fish migration barriers, pipe outfalls, in-stream construction sites and trash dumping locations. (Each of these terms are officially defined in the report downloads below and in the State of Maryland’s SCA Survey Protocols document available for download from Maryland’s Department of Natural Resources, Watershed Restoration Division.

Sligo Creek SCA

The map and report linked below show problems identified by the SCA protocol on the Anacostia River’s Sligo Creek tributary. AWS encourages citizens to visit listed sites to see environmental damage firsthand. Since stream banks change constantly, the features you see may differ from pictures shown in our report or on our map.
