Chain of Rocks Lock Chain of Rocks Lock, also known as Locks No. 27, is a lock situated at the southern end of Chouteau Island near St. Louis, Missouri on the Upper Mississippi River. Its associated dam is just downstream of the Chain of Rocks Bridge, and the lock is located over 3 mi southeast on the Chain of Rocks canal. The canal and locks allow river traffic to bypass a portion of the river that is unnavigable in low water due to an anticlinal exposure of bedrock in the river—a "chain of rocks".

Dismal Swamp Canal 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 route runs through bays, lakes, rivers, streams, and canals, and includes the Intracoastal Waterway running from Norfolk, Virginia, to the Florida Keys.

North Walsham &amp; Dilham Canal The North Walsham and Dilham Canal is a waterway in the English county of Norfolk. It was authorised by Parliament in 1812, but work on the construction of a canal which ran parallel to a branch of the River Ant did not start until 1825. It included six locks, which were sized to accommodate wherries, and was officially opened in August 1826. It was 8.7 mi long and ran from two bone mills at Antingham to a junction with the River Ant at Smallburgh. It carried offal for the bone mills and agricultural products, as it proved cheaper to land coal on the beach at Mundesley and cart it overland than to use the canal.

James T. Staples James T. Staples, officially registered as the Jas. T. Staples and also known as the Big Jim, was a Tombigbee River sternwheel paddle steamer that ran a route between Mobile and Demopolis, Alabama, during the early 20th century. She was destroyed during 1913 in an explosion while docked on the Tombigbee roughly six miles (10 km) north of the current Coffeeville Lock and Dam. It was the last major maritime disaster involving a steamboat in Tombigbee River history. The disaster saw the ship enter southwestern Alabama folklore, with tales that its sinking had been foretold by supernatural occurrences.

Chain boat navigation Chain-boat navigation or chain-ship navigation is a little-known chapter in the history of shipping on European rivers. From around the middle of the 19th century, vessels called chain boats were used to haul strings of barges upstream by using a fixed chain lying on the bed of a river. The chain was raised from the riverbed to pass over the deck of the steamer, being hauled by a heavy winch powered by a steam engine. A variety of companies operated chain boat services on rivers such as the Elbe, Rhine, Neckar, Main, Saale, Havel, Spree and Saône as well as other rivers in Belgium and the Netherlands. Chain boats were also used in the United States.

St. Johns River The St. Johns River (Spanish: "Río San Juan" ) is the longest river in the U.S. state of Florida and its most significant one for commercial and recreational use. At 310 mi long, it winds through or borders twelve counties, three of which are the state's largest. The drop in elevation from headwaters to mouth is less than 30 ft ; like most Florida waterways, the St. Johns has a very low flow rate 0.3 mph and is often described as "lazy". Popular belief in the St. Johns area holds that it is one of the few rivers that flow north, although north-flowing rivers are common. Numerous lakes are formed by the river or flow into it, but as a river its widest point is nearly 3 mi across. The narrowest point is in the headwaters, an unnavigable marsh in Indian River County. The St. Johns drainage basin of 8840 sqmi includes some of Florida's major wetlands. It is separated into three major basins and two associated watersheds for Lake George and the Ocklawaha River, all managed by the St. Johns River Water Management District.

Baillie-Grohman Canal The Baillie-Grohman Canal was a shipping canal between the headwaters of the Columbia River and the upper Kootenay River in the East Kootenay region of British Columbia at a place now known as Canal Flats, BC. The construction of the canal was required by the provincial government of British Columbia as a condition of the canal's promoter receiving substantial land concessions from the provincial government of British Columbia in the area of Creston, BC. The promoter, William Adolf Baillie-Grohman (1851–1921), was a wealthy adventurer, hunter author, and business promoter. He declared the canal to be complete in 1889. The canal was an expensive failure, being used only three times during its entire existence. In 1902, on the last use by a vessel, the sternwheeler "North Star", the sternwheeler's captain, Frank P. Armstrong deliberately blew out the canal's lower lock gates with dynamite to allow the transit of his vessel.

Cape Florida Light The Cape Florida Light is a lighthouse on Cape Florida at the south end of Key Biscayne in Miami-Dade County, Florida. Constructed in 1825, it guided mariners off the Florida Reef, which starts near Key Biscayne and extends southward a few miles offshore of the Florida Keys. It was operated by staff, with interruptions, until 1878, when it was replaced by the Fowey Rocks lighthouse. The lighthouse was put back into use in 1978 by the U.S. Coast Guard to mark the Florida Channel, the deepest natural channel into Biscayne Bay. They decommissioned it in 1990.

Newichawannock Canal The Newichawannock Canal is a man-made canal which drains Great East Lake into Horn Pond at the border between Wakefield, New Hampshire, and Acton, Maine, in the northeastern United States. It is at the head of the Salmon Falls River, which the Abenaki called "Newichawannock", meaning "river with many falls". Begun in 1850 by the Great Falls Company to increase the water available for its mills in Somersworth, New Hampshire, the 0.75 mi canal is unusual as it was built for strictly industrial purposes in an area remote from the actual industrial site. The canal forms the boundary between the states of New Hampshire and Maine, and is spanned by a stone bridge built at the same time. The canal and bridge, along with related artifacts, were listed on the National Register of Historic Places in 2014.
