Swan Creek Wetlands | Cox Creek Dredged Material Containment Facility
CLOSED FOR DROP-IN BIRDING UNTIL FURTHER NOTICE
1000 Kembo Road, Curtis Bay, Maryland 21226
Swan Creek Wetlands and Cox Creek Dredged Material Containment Facility (DMCF) is CLOSED FOR DROP-IN BIRDING UNTIL FURTHER NOTICE. The facility is undergoing heavy construction and for safety reasons has been closed for drop-in birding. During the construction phase, which may last several years, there may be limited opportunities for organized birding trips with local clubs. Such trips will have a restricted number of participants and will require advance reservations. Check the calendar on the MOS website for possible trips.
Swan Creek and Cox Creek are located just south of the Francis Scott Key Bridge and the Baltimore Beltway (I-695), on the Patapsco River near its junction with the Chesapeake Bay. The site is known as a magnet for shorebirds and waders and is one of three dredged material sites in Maryland that are open to birding, the others being Hart-Miller Island State Park (Baltimore County) and Poplar Island (Talbot County). Visiting any of these facilities is always a great treat for birders because of their propensity to attract hard-to-find shorebirds and rarities. Cox Creek became famous in 2017 when it hosted a state first-record Sharp-tailed Sandpiper that dropped in for a couple of days during fall migration.
Upon arrival at Swan Creek/Cox Creek, the first thing you will see are the Cox Creek dredged material containment cells, not accessible to the public but visible from the visitor area by the office trailer. Cox Creek was built to hold material dredged from the shipping channels that lead to the Baltimore Harbor. The resulting slurry of mud and water in the two large impoundments provides an attractive stopover for migrants, and rarities frequently occur, especially in the shorebird category. If you are visiting on your own, as opposed to being on a guided tour with a bird club, you are not permitted to walk the dikes around the containment cells (aka impoundments). Instead, you must view the impoundments from a spot near the flagpole outside the office trailer. A scope will absolutely be needed, as the impoundments are large and most of the interesting birds have the annoying habit of being on the far side. While scoping, spend sometime carefully examining the metal struts on top of and under the Key Bridge: sometimes a Peregrine Falcon or two can be found there.
The adjoining Swan Creek Wetlands cannot be seen from the area near the office trailer; the wetlands are just to the south, on the other side of a little wooded strip. To reach the wetlands, walk south (to the right as you enter the facility) on the rock-rubble road that leads away from the office trailer. The trail to the wetland doubles as a heavy-equipment road and has minor slopes, and can be challenging because of mud, rock rubble, and water flowing over one section, so wear sturdy, closed-toe waterproof footwear. Here, over 100 acres have been permanently preserved for wildlife habitat, and 11 acres of tidal wetlands have been enhanced and restored. Habitats include open water, low marsh with non-vegetated tidal flats, saltbush assemblages, woodlands, and a beach/sand bar area. A viewing platform overlooks part of the wetland. Don’t forget to bird the woods on the way to the wetland; this small woodlot often attracts flycatchers, vireos, warblers, and orioles in season. Also be sure to scan the water from the beach area, looking for loons, grebes, and waterfowl in winter, terns in summer, and gulls all year long. The industrial facility on the shoreline to the south of Swan Creek has a long pier that attracts roosting gulls. Far off-shore, historic Fort Carroll, a Civil War-era fortification, can be seen on a small island just south of the Key Bridge, and the Fort also attracts gulls.
Occasionally, special field trips at Swan Creek/Cox Creek are scheduled through local bird clubs and these trips are given special permission to walk the dikes around the containment facility cells, affording great views of birds in the impoundments. Such field trips have limited capacity and always require advance registration. Check the calendar on the Maryland Ornithology Society website to see if any such trips are coming up.
When the facility is operating normally and is open to drop-in birding, birders are required to complete a Release Form (one time) and sign the Registration Book (each visit) in the Maryland Environmental Service (MES) office trailer (to the left of the flag pole as you enter the site). Please be sure to leave promptly by the posted closing time. Visitors on the property after hours may be arrested or fined.

For birders who are mobility-impaired, Swan Creek offers good views of the impoundments from the area near the flagpole next to the administration office/trailer. Parking is located just a short distance away and the area between the parking and the flagpole is paved or gravel. The trail to the restored wetland is not wheelchair-accessible. ◾ Swan Creek/Cox Creek DMCF often hosts visiting school groups for environmental education activities. ◾ The local chapter of the Maryland Ornithological Society is the Anne Arundel Bird Club, which offers field trips and meetings with informative programs, all free and open to the public.
From the southern portion of the Baltimore Beltway/I-695: Take exit 1 (exit is immediately west of the Key Bridge). From the exit, head south on MD Route 173 South/Fort Smallwood Road. Drive two miles, passing the Under Armour complex on the left, and turn left to go east on Kembo Road. Follow Kembo Road to near its end and park along the chain link fence on the right, outside of the gate. Walk through the gate and sign in at the office (metal trailer near the flagpole). Also complete a release form if you have not already done so.
