Anne Arundel County Department of Public Works - Watershed, Ecosystems and Restoration Service, MD requested the Chesapeake Bay Field Office to develop standard protocols for stream assessment and to provide instruction and training on applying the protocols. Currently, there are numerous methods used to assess stream conditions, which made review of these assessments difficult. The benefits of utilizing this stream assessment protocol include: standardized methods, consistent and comparable data, improved quality of data and reduced review efforts and time.

 

The stream assessment protocol consists of limits of investigation, rapid stream assessment and detailed stream assessment. Currently county regulations require a developer to determine the limits based on a man-made or natural restriction point downstream of a project. This protocol determines the limits based on the potential total downstream effects from the proposed development.

 

The rapid assessment has two components: stream characterization and stability assessment. The data collected includes general watershed characteristics, bankfull determination, stream classification, vertical stability lateral stability and overall reach stability.  The detailed assessment follows the methodology developed by David Rosgen. Its four main components include bankfull determination, stream characterization, reference reach survey, and stability condition assessment.

 

This protocol can be used by stream practitioners to document and evaluate the existing condition of streams throughout the United States.
