Dismal Swamp State Park is a North Carolina state park in Camden County, North Carolina in the United States.
 The park was created as a state natural area in 1974 with the help of The Nature Conservancy, and on July 28, 2007 the NC General Assembly re-designated it as a state park.
 It opened to the public in 2008.
 This marked the first time that public access to Great Dismal Swamp was made possible in North Carolina.
 The park covers 14432 acre of protected land on the North Carolina/Virginia border.
 Park offices are three miles (5 km) south of the border on U.S. Route 17 near South Mills.
 Features of the park include the canal which is used regularly by boaters using the Intracoastal Waterway and several miles of hiking and biking trails.
The Bayport Container Terminal, or simply the Bayport Terminal, is a major deep water port in the Greater Houston area in Texas (United States).
 This relatively new terminal, part of the Port of Houston, is designed to handle standardized cargo containers and offload the nearby Barbours Cut Terminal, which has no further room for expansion.
 The Bayport Terminal is situated along the Bayport Ship Channel off Galveston Bay, between La Porte, Texas and Seabrook, Texas (adjacent to Shoreacres and El Jardin).
 This channel itself feeds into to the larger Houston Ship Channel, which runs from Houston, through Galveston Bay, to the Gulf of Mexico.
Currituck Sound is a protected inlet of the Atlantic Ocean, located in northeastern part of North Carolina and extreme southeastern Virginia.
 Thirty miles N-S and 3–8 miles wide, this shallow, island-filled sound is separated from the ocean by the Currituck Banks Peninsula (formerly Bodie Island), part of the Outer Banks.
 On the NE, it extends to Back Bay in Virginia Beach, Virginia.
 A fork on the northwest leads to the Albemarle and Chesapeake Canal, which is a part of the Atlantic Intracoastal Waterway that connects the sound to Hampton Roads and the Chesapeake Bay.
 Although several inlets connected it directly to the Atlantic at one time or another, they have all since closed and there is now no direct access to the Ocean from the Sound.
 This has caused the salinity levels to be significantly lower than they had been historically.
 Currently, the only access to the Ocean is through the Albemarle Sound, which joins the Currituck to the South.
 Currituck County's Mackay Island and Currituck National Wildlife Refuge as well as Back Bay National Wildlife Refuge and False Cape State Park in Virginia Beach border the sound and are winter habitats on the Atlantic Flyway.
 Many watersports activities occur in the sound, including parasailing, sea kayaking, and jet skiing.
 An area of barrier beaches, it is also noted for its duck and goose hunting.
The Manasquan Inlet is an inlet that connects the Atlantic Ocean with the Manasquan River, dividing the counties of Ocean County and Monmouth County in the state of New Jersey.

 It was completed in late 1925 to connect the Manasquan Inlet and Manasquan River with Bay Head Harbor on the northern end of the Barnegat Bay.
 It is also a section of the Intracoastal Waterway.
The Port of Lake Charles is an industrial port based in the city of Lake Charles, Louisiana, U.S.A.

The Dismal Swamp Canal is located along the eastern edge of the Great Dismal Swamp in Virginia and North Carolina in the United States.
 It is the oldest continually operating man-made canal in the United States, opened in 1805, and closed in October 2016.
 It is part of the Intracoastal Waterway, an inland route, which parallels the east coast and offers boaters shelter from the Atlantic Ocean from Manasquan Inlet, New Jersey, to Brownsville, Texas.

The Manasquan River is a 26.5 mi waterway in central New Jersey.
 It flows from central Monmouth County, beginning in Freehold Township, to the Atlantic Ocean, where it empties between the communities of Manasquan and Point Pleasant via the Manasquan Inlet.
 It widens greatly as it nears the ocean, making it ideal for boating, and is a very popular recreational area of the Jersey Shore.
 The Manasquan River and Inlet is the unofficial northernmost terminus of the Intracoastal Waterway.
