Upper Patuxent River Watershed Assessment

Biohabitats, along with the prime contractor, Limnotech, Inc., was contracted to perform an assessment of 171 miles of perennial streams within the Upper Patuxent River watershed. The Upper Patuxent River watershed includes 19 subwatersheds. It is primarily agricultural in nature, with some areas of residential, commercial and forested land. Portions of the watershed lie within the Patuxent National Wildlife Refuge.

The effort consisted of mapping perennial streams, breaking the streams down into reaches and performing habitat assessment on each reach, all while identifying other significant stream characteristics. Biohabitats was tasked with identify parameters such as debris jams, head cuts, dumpsites, culverts and utility crossings, just to name a few. The data was collected using hand-held GPS devices for entry into a database created by Anne Arundel County. The data is being used by the County to identify capital improvement projects and to provide an overall view of the condition of individual subwatersheds.
