He didn't. The Duke of Bridgewater had a canal built from his coal mines in Worsley to the centre of Manchester. This is not in London. The first part of his canal opened in 1763. He didn't invent canals, though. The Sankey Canal near Warrington had already opened a few years earlier. The Duke went to look at the Canal du Midi in France and the Newry Canal in Ireland, which were older. The Exeter Ship Canal had opened back in 1566 and a number of canals were built in England by the Romans, including the Foss Dyke,which is still in use, between Lincoln and the River Trent.

A canal outlet refers to a structure or opening through which water is discharged from a canal system. It is a crucial component of an irrigation network that allows the controlled release of water from a canal to supply irrigation channels, fields, or other water distribution systems. The canal outlet serves to regulate the flow of water, ensuring it is distributed appropriately and efficiently. Canal outlets can take various forms depending on the design and purpose. Some common types of canal outlets include: Head Regulator: A head regulator is a type of canal outlet that is typically located at the beginning of a canal system. It is used to control the flow of water into the main canal from the water source, such as a river or reservoir. Distributary Regulator: A distributary regulator is a structure located along a canal where it branches off into multiple distributaries. It regulates the flow of water into each distributary, ensuring an equitable distribution of water to different irrigation channels or fields. Flume: A flume is a channel or chute-like structure used to carry water from a canal to an irrigation channel or field. It is often made of concrete or lined with a smooth surface to minimize water loss due to seepage. Flumes can be designed to maintain a constant water level and control the flow rate. Turnout: A turnout is an outlet structure that diverts water from a main canal into a smaller irrigation channel. It allows water to be directed to specific fields or areas for irrigation purposes. Sluice Gate: A sluice gate is a mechanism used to control the flow of water at a canal outlet. It consists of a movable gate or barrier that can be raised or lowered to adjust the water level or stop the flow completely. Canal outlets play a vital role in managing water resources efficiently, ensuring that water is distributed effectively to meet agricultural, industrial, or domestic water needs. The design and operation of canal outlets aim to minimize water loss, maintain flow control, and optimize water distribution for irrigation and other purposes.
