The Chelmer and Blackwater Navigation is the canalisation of the Rivers Chelmer and Blackwater in Essex, in the east of England. The navigation runs for 13.75 miles (22.13 km) from Springfield Basin in Chelmsford to the sea lock at Heybridge Basin near Maldon. Initial plans faced spirited opposition from Maldon, which were overcome by avoiding the town and terminating at Heybridge, and the navigation opened in 1797. There were some teething problems, and the engineer John Rennie was called back on two occasions to recommend improvements. The impact of the railways was less severe than on many canals, as there was never a direct line between Chelmsford and Maldon. The sea lock at Heybridge was enlarged after the Second World War, but trade gradually declined and ceased in 1972.
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a fixed chamber in which the water level can be varied; whereas in a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself that rises and falls.
The Lake Washington Ship Canal, which runs through the city of Seattle, connects the fresh water body of Lake Washington with the salt water inland sea of Puget Sound. The Hiram M. Chittenden Locks accommodate the approximately 20-foot (6.1 m) difference in water level between Lake Washington and the sound. The canal runs east–west and connects Union Bay, the Montlake Cut, Portage Bay, Lake Union, the Fremont Cut, Salmon Bay, and Shilshole Bay, which is part of the sound.
The St. Marys River, sometimes written St. Mary's River, drains Lake Superior, starting at the end of Whitefish Bay and flowing 74.5 miles (119.9 km) southeast into Lake Huron, with a fall of 23 feet (7.0 m). For its entire length it is an international border, separating Michigan in the United States from Ontario, Canada.
The Welland Canal is a ship canal in Ontario, Canada, and part of the St. Lawrence Seaway and Great Lakes Waterway. The canal traverses the Niagara Peninsula between Port Weller on Lake Ontario, and Port Colborne on Lake Erie, and was erected because the Niagara River—the only natural waterway connecting the lakes—was unnavigable due to Niagara Falls. The Welland Canal enables ships to ascend and descend the Niagara Escarpment, and has followed four different routes since it opened.
The Chesapeake & Delaware Canal is a 14-mile (22.5 km)-long, 450-foot (137.2 m)-wide and 35-foot (10.7 m)-deep ship canal that connects the Delaware River with the Chesapeake Bay in the states of Delaware and Maryland in the United States.
The River Weaver is a river, navigable in its lower reaches, running in a curving route anti-clockwise across west Cheshire, northern England. Improvements to the river to make it navigable were authorised in 1720 and the work, which included eleven locks, was completed in 1732. An unusual clause in the enabling Act of Parliament stipulated that profits should be given to the County of Cheshire for the improvement of roads and bridges, but the navigation was not initially profitable, and it was 1775 before the first payments were made. Trade continued to rise, and by 1845, over £500,000 had been given to the county.
The Calumet River is a system of heavily industrialized rivers and canals in the region between the south side of Chicago, Illinois, and the city of Gary, Indiana. Historically, the Little Calumet River and the Grand Calumet River were one, the former flowing west from Indiana into Illinois, then turning back east to its mouth at Lake Michigan at Marquette Park in Gary. Now the system is part of the Chicago Area Waterway System and through the use of locks flows away from Lake Michigan to the Cal-Sag Channel.
The Fox–Wisconsin Waterway is a waterway formed by the Fox and Wisconsin Rivers. First used by European settlers in 1673 during the expedition of Marquette & Joliet, it was one of the principal routes used by travelers between the Great Lakes and the Mississippi River until the completion of the Illinois and Michigan Canal in 1848 and the arrival of railroads. The western terminus of the Fox–Wisconsin Waterway was at the Mississippi at Prairie du Chien, Wisconsin. It continued up the Wisconsin River about 116 miles (187 km) until reaching Portage, Wisconsin. There travelers would portage to the Upper Fox River, or eventually, use the Portage Canal. It continued about 160 miles (260 km) down the Fox River, following it through Lake Winnebago and continuing on the Lower Fox over 170 feet of falls to the eastern terminus of Green Bay.
The Montgomery Canal, known colloquially as "The Monty", is a partially restored canal in eastern Powys and northwest Shropshire. The canal runs 33 miles (53 km) from the Llangollen Canal at Frankton Junction to Newtown via Llanymynech and Welshpool and crosses the England–Wales border.
Neptune's Staircase is a staircase lock comprising eight locks on the Caledonian Canal. Built by Thomas Telford between 1803 and 1822, it is the longest staircase lock in Britain. The system was originally hand-powered but has been converted to hydraulic operation.
The Millennium Ribble Link is a linear water park and new navigation which links the once-isolated Lancaster Canal in Lancashire, England to the River Ribble. The Lancaster Canal was never connected to the rest of the English waterways network, because the planned aqueduct over the River Ribble was never built. Instead, a tramway connected the southern and northern parts of the canal. An idea for a connecting link following the course of the Savick Brook was proposed in 1979, and the Ribble Link Trust campaigned for twenty years to see it built. The turn of the Millennium, and the funds available from the Millennium Commission for projects to mark the event was the catalyst for the project to be implemented, and although completion was delayed, the navigation opened in July 2002.
The Hennepin Canal State Trail, also just called the Hennepin Canal, is an abandoned waterway in northwest Illinois, between the Mississippi River at Rock Island and the Illinois River near Hennepin. The entire canal is listed on the National Register of Historic Places.
The Industrial Canal is a 5.5 mile (9 km) waterway in New Orleans, Louisiana, United States. The waterway's proper name, as used by the U.S. Army Corps of Engineers and on NOAA nautical charts, is Inner Harbor Navigation Canal (IHNC). The more common "Industrial Canal" name is used locally, both by commercial mariners and by landside residents.
The Inner Harbor Navigation Canal Lock—commonly known as Industrial Canal Lock or simply Industrial Lock—is a navigation lock in New Orleans. It connects the Lower Mississippi River to the Industrial Canal and other sea-level waterways. Because it is shorter and narrower than most modern locks on the Mississippi River System, the 1920s vintage lock has become a bottleneck between the nation's two highest-tonnage waterways—the Mississippi and the Gulf Intracoastal Waterway.
The Sault Ste. Marie Canal is a National Historic Site in Sault Ste. Marie, Ontario, and is part of the national park system, managed by Parks Canada. It includes a lock to bypass the rapids on the St. Marys River.
The Willamette Falls Locks are a lock system on the Willamette River in the U.S. state of Oregon. Opened in 1873 and closed since 2011, they allowed boat traffic on the Willamette to navigate beyond Willamette Falls and the T.W. Sullivan Dam. Since their closure in 2011 the locks are classified to be in a "non-operational status" and are expected to remain permanently closed.
The Stroudwater Navigation is a canal in Gloucestershire, England which linked Stroud to the River Severn. It was authorised in 1776, although part had already been built, as the proprietors believed that an Act of Parliament obtained in 1730 gave them the necessary powers. Opened in 1779, it was a commercial success, its main cargo being coal. It was 8 miles (13 km) in length and had a rise of 102 ft 5 in (31.22 m) through 12 locks. Following the opening of the Thames and Severn Canal in 1789, it formed part of a through route from Bristol to London, although much of its trade vanished when the Kennet and Avon Canal provided a more direct route in 1810. Despite competition from the railways, the canal continued to pay dividends to shareholders until 1922, and was not finally abandoned until 1954.
Starved Rock Lock and Dam, also known as Lock and Dam No. 6, is a lock and dam facility managed by the U.S. Army Corps of Engineers along the Illinois River. It is part of the Illinois Waterway and was constructed between 1926 and 1933. The lock and dam was added to the National Register of Historic Places as the Starved Rock Lock and Dam Historic District in 2004.
The Kaukauna Locks Historic District is a lock and dam system in Kaukauna, Wisconsin, United States, that carried boat traffic around a rapids of the Fox River starting in the 1850s as part of the Fox–Wisconsin Waterway. It was added to the National Register of Historic Places in 1993 for its significance in engineering and transport.
