From the Mountains to the Bay
Maryland's freshwater streams are unique in that they run to the largest estuary in the United States. The fingers of the Chesapeake Bay reach every corner of the state, from the Appalachians to the Eastern Shore. In turn, the health of our freshwater resources directly influences the health of the Bay. Monitoring these resources is essential in determining what we can do to preserve and protect not only the Bay, but also the waters in our backyard. Our streams provide recreation opportunities such as canoeing and fishing, grow our crops, feed our reservoirs, and provide valuable habitat for wildlife.
The Monitoring and Non-Tidal Assessment Division (MANTA)
This section of the Department of Natural Resources website contains scientific information about the non-tidal freshwater streams and rivers of Maryland, DNR monitoring programs, and volunteering opportunities with the Stream Waders. You can request data collected from the Maryland Biological Stream Survey, browse publications and reports from other projects, and view agendas for upcoming talks and meetings.
