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 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 Leven Canal runs for 3.18 miles (5.1 km) from the River Hull to the village of Leven, East Riding of Yorkshire, England. It was built for Mrs Charlotta Bethell in 1805, and remained in use until 1935. It is now a Site of Special Scientific Interest.
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. It was opened in July 2002.
The New Junction Canal is a canal in South Yorkshire, England. It is part of the Sheffield and South Yorkshire Navigation (S&SYN), although it was jointly funded by the Aire and Calder Navigation, and was opened in 1905. It links the River Don Navigation and the Stainforth and Keadby Canal with the Aire and Calder Navigation. It is completely straight, and was the last canal built in England for commercial purposes.
The Market Weighton Canal ran 9.5 miles (15.3 km) from the Humber Estuary to its terminus near Market Weighton. It gained its Act of Parliament in 1772 and opened in 1782. The 3.5 miles (5.6 km) closest to Market Weighton was abandoned in 1900 and the right of navigation through Weighton lock was lost in 1971. However, as of 2002 the lock was passable and the canal usable up to the junction with the River Foulness where silt has made it impassable. Also there is no right of navigation under the M62 motorway bridge to the north of Newport.
Bethells Bridge, a swing bridge on the Driffield Navigation in the East Riding of Yorkshire, England. The bridge was built to access land cut off after a new section of canal was made. It is now home to many boat moorings, and popular with fishermen.
Struncheon Hill Lock was built as a later addition to the Driffield Navigation in the East Riding of Yorkshire, England. It improved access to the next section of water during low tide conditions, and is the first lock. It is sometimes known as "Top Hill Low", which is the name of the large pumping station located there.
Aike Beck or the Lockington Navigation was a stream in the East Riding of Yorkshire, England, which was constructed as a navigation in the late 18th century, and ceased to function as such in the 1850s. The water supply came from Bryan Mills Beck and Scorborough Beck, but in 1988, these were diverted to feed into Arram Beck, and most of the channel was filled in with material from the flood banks.
West Beck is the common name given to the upper section of the old River Hull, as it rises in the foothills of the Yorkshire Wolds. After reaching Frodingham Beck at Emmotland, it becomes called the River Hull. It is noteworthy for being the most northerly chalk stream in England. It provides fly fishing for wild brown trout and grayling.
The Stainforth and Keadby Canal is a navigable canal in South Yorkshire and Lincolnshire, England. It connects the River Don Navigation at Bramwith to the River Trent at Keadby, by way of Stainforth, Thorne and Ealand, near Crowle. It opened in 1802, passed into the control of the River Don Navigation in 1849, and within a year was controlled by the first of several railway companies. It became part of the Sheffield and South Yorkshire Navigation, an attempt to remove several canals from railway control, in 1895. There were plans to upgrade it to take larger barges and to improve the port facilities at Keadby, but the completion of the New Junction Canal in 1905 made this unnecessary, as Goole could easily be reached and was already a thriving port.
Bow Locks (No20) is a set of bi-directional locks in Bromley-by-Bow in the London Borough of Tower Hamlets and Newham. The locks link the tidal Bow Creek to the River Lee Navigation, which is a canalised river. These locks were first built in 1850 and then rebuilt in 1930, at the same time as the Prescott Channel was cut nearby. At high tide, the tide from Bow Creek formerly flowed through Bow Locks, to raise the level of the canals, such as the Limehouse Cut. In 2000, these locks were modified to keep the tide out, to reduce silting in the canal system.
Hull Bridge is a village in the East Riding of Yorkshire, England. It is situated approximately 1.5 miles (2.4 km) north-east of Beverley town centre. It lies south of the A1035 road and straddles the Beverley and Barmston Drain and the River Hull from which it takes its name.
The River Don Navigation was the result of early efforts to make the River Don in South Yorkshire, England, navigable between Fishlake and Sheffield. The Dutch engineer Cornelius Vermuyden had re-routed the mouth of the river in 1626, to improve drainage, and the new works included provision for navigation, but the scheme did not solve the problem of flooding, and the Dutch River was cut in 1635 to link the new channel to Goole. The first Act of Parliament to improve navigation on the river was obtained in 1726, by a group of Cutlers based in Sheffield; the Corporation of Doncaster obtained an Act in the following year for improvements to the lower river. Locks and lock cuts were built, and, by 1751, the river was navigable to Tinsley.
The Mersey and Irwell Navigation was a river navigation in North West England, which provided a navigable route from the Mersey estuary to Salford and Manchester, by improving the course of the River Irwell and the River Mersey. Eight locks were constructed between 1724 and 1734, and the rivers were improved by the construction of new cuts several times subsequently. Use of the navigation declined from the 1870s, and it was ultimately superseded by the Manchester Ship Canal, the construction of which destroyed most of the Irwell section of the navigation and the long cut between Latchford and Runcorn.
Wansford Lock was built as part of the Driffield Navigation in the East Riding of Yorkshire, England. It was opened in 1770, and restored in 2009. It was designated Grade II in 1985.
Whinhill Lock was built as part of the Driffield Navigation in the East Riding of Yorkshire, England. It was originally opened in 1770, and was restored in 2004.
