Navigable in the context of Under keel clearance

Lake Titicaca (/tɪtɪˈkɑːkə/; Spanish: Lago Titicaca [ˈlaɣo titiˈkaka]; Quechua: Titiqaqa and Aymara: Titiqaqa) is a large freshwater lake in the Andes mountains on the border of Bolivia and Peru. It is often called the highest navigable lake in the world. Titicaca is the largest lake in South America, both in terms of the volume of water and surface area. It is the 18th largest lake in the world. It has a surface elevation of 3,812 m (12,507 ft).

A sea lane, sea road or shipping lane is a regularly used navigable route for large water vessels (ships) on wide waterways such as oceans and large lakes, and is preferably safe, direct and economic. During the Age of Sail, they were determined by the distribution of land masses but also by the prevailing winds, whose discovery was crucial for the success of long maritime voyages. Sea lanes are very important for seaborne trade.

Pumping stations, also called pumphouses, are public utility buildings containing pumps and equipment for pumping fluids from one place to another. They are critical in a variety of infrastructure systems, such as water supply, drainage of low-lying land, canals and removal of sewage to processing sites. A pumping station is an integral part of a pumped-storage hydroelectricity installation.

Pumping stations are designed to move water or sewage from one location to another, overcoming gravitational challenges, and are essential for maintaining navigable canal levels, supplying water, and managing sewage and floodwaters. In canal systems, pumping stations help replenish water lost through lock usage and leakage, ensuring navigability. Similarly, in land drainage, stations pump water to prevent flooding in areas below sea level, a concept pioneered during the Victorian era in places like The Fens in the UK. The introduction of "package pumping stations" has modernized drainage systems, allowing a compact, efficient solution for areas where gravity drainage is impractical.

The Strait of Magellan (Spanish: Estrecho de Magallanes), also called the Straits of Magellan, is a navigable sea route in southern Chile separating mainland South America to the north and the Tierra del Fuego archipelago to the south. Considered the most important natural passage between the Atlantic and Pacific oceans, the strait is approximately 570 km (310 nmi; 350 mi) long and 2 km (1.1 nmi; 1.2 mi) wide at its narrowest point. In 1520, the Spanish expedition of the Portuguese navigator Ferdinand Magellan, after whom the strait is named, became the first Europeans to discover it.

Magellan's original name for the strait was Estrecho de Todos los Santos ("Strait of All Saints"). The King of Spain, Emperor Charles V, who had sponsored the Magellan-Elcano expedition, changed the name to the Strait of Magellan in honor of Magellan.

The Intracoastal Waterway (ICW) is a 3,000-mile (4,800 km) inland waterway along the Atlantic and Gulf of Mexico coasts of the United States, running from Massachusetts southward along the Atlantic Seaboard and around the southern tip of Florida, then following the Gulf Coast to Brownsville, Texas. Some sections of the waterway consist of natural inlets, saltwater rivers, bays, and sounds, while others are artificial canals. Maintained, improved, and extensively dredged where necessary by the United States Army Corps of Engineers, it provides a navigable route along its length without many of the hazards of travel on the open sea.

The St. Lawrence Seaway (French: la Voie Maritime du Saint-Laurent) is a system of rivers, locks, canals and channels in Eastern Canada and the Northern United States that permits oceangoing vessels to travel from the Atlantic Ocean to the Great Lakes of North America, as far inland as Duluth, Minnesota, at the western end of Lake Superior. The seaway is named for the St. Lawrence River, which flows straight from Lake Ontario to the Atlantic Gulf of St. Lawrence. Legally, the seaway extends from Montreal, Quebec, to Lake Erie, and includes the Welland Canal. Ships from the Atlantic Ocean are able to reach ports in all five of the Great Lakes via the Great Lakes Waterway.

The St. Lawrence River portion of the seaway is not a continuous waterway; rather, it consists of several stretches of navigable channels within the river, a number of locks, and canals along the banks of the St. Lawrence River to bypass several rapids and dams. A number of the locks are managed by the St. Lawrence Seaway Management Corporation in Canada, and others in the United States by the Great Lakes St. Lawrence Seaway Development Corporation; the two bodies together advertise the seaway as part of "Highway H₂O". The section of the river from Montreal to the Atlantic Ocean is under Canadian jurisdiction, regulated by the offices of Transport Canada in the Port of Quebec.

Navigable aqueducts (sometimes called navigable water bridges or canal bridges) are bridge structures that carry navigable waterway canals over other rivers, valleys, railways or roads. They are primarily distinguished by their size, carrying a larger cross-section of water than most water-supply aqueducts. Roman aqueducts were used to transport water and were created in ancient Rome. The 662-metre (2,172 ft) long steel Briare aqueduct carrying the Canal latéral à la Loire over the River Loire was built in 1896. It was ranked as the longest navigable aqueduct in the world for more than a century, until the Magdeburg Water Bridge in Germany took the title in the early 21st century.

Early aqueducts such as the three on the Canal du Midi had stone or brick arches, the longest span being 18.3 metres (60 ft) on the Cesse Aqueduct, built in 1690. But, the weight of the construction to support the trough with the clay or other lining to make it waterproof made these structures clumsy. In 1796 Longdon-on-Tern Aqueduct, the first large cast iron aqueduct was built by Thomas Telford at Longdon-on-Tern on the Shrewsbury Canal. It has a total length of 57 metres (187 ft) across three intermediate piers. Within ten years Telford had completed the far more ambitious Pontcysyllte Aqueduct in Wales on the Llangollen Canal over the River Dee valley, with a total length 307 metres and a height of 38 metres, making it the tallest navigable aqueduct in the world. Other cast-iron aqueducts followed, such as the single-span Stanley Ferry Aqueduct on the Calder and Hebble Navigation in 1839, with its innovative 50-metre (160 ft) through arch design.

The River Wey Navigation and Godalming Navigation together provide a 20-mile (32 km) continuous navigable route from the River Thames near Weybridge via Guildford to Godalming (commonly called the Wey Navigation). Both waterways are in Surrey and are owned by the National Trust. The River Wey Navigation connects to the Basingstoke Canal at West Byfleet, and the Godalming Navigation to the Wey and Arun Canal near Shalford. The navigations consist of both man-made canal cuts and adapted (dredged and straightened) parts of the River Wey.

The Wey was one of the first rivers in England to be made navigable; the River Wey Navigation opened in 1653, with 12 locks between Weybridge and Guildford, and the Godalming Navigation, with a further four locks, was completed in 1764. Commercial traffic ceased as late as 1983 and the Wey Navigation and the Godalming Navigation were donated to the National Trust in 1964 and 1968 respectively.

The Karakum Canal (Qaraqum Canal, Kara Kum Canal, Garagum Canal; Russian: Каракумский канал, Karakumskiy Kanal, Turkmen: Garagum kanaly, قاراقۇم کانالیٛ, Гарагум каналы) in Turkmenistan is one of the largest irrigation and water supply canals in the world. Started in 1954, and completed in 1988, it is navigable over much of its 1,375-kilometre (854 mi) length, and carries 13 cubic kilometres (3.1 cu mi) of water annually from the Amu-Darya River across the Karakum Desert in Turkmenistan. The canal opened up huge new tracts of land to agriculture, especially to cotton monoculture heavily promoted by the Soviet Union, and supplying Ashgabat with a major source of water. The canal is also a major factor leading to the Aral Sea environmental disaster. The Soviet regime planned to at some time extend the canal to the Caspian Sea.

Turag River (Bengali: তুরাগ নদ; [t̪uraɡ nɔd̪]) is the upper tributary of the Buriganga, a major river in Bangladesh. The Turag originates from the Bangshi River, the latter an important tributary of the Dhaleshwari River, flows through Gazipur and joins the Buriganga at Mirpur in Dhaka District. It is navigable by boat all year round.

The Turag suffers from infilling along its banks, which restricts its flow. Sedimentation that reduces the flow may have begun as early as the 1950 Assam–Tibet earthquake. It also suffers from acute water pollution. While attempts have been made to marginally widen the river, the majority of industry has made little effort to follow environmental laws and the water has become visibly discolored and polluted.
