Canal Pound
A canal pound (from impound), reach, or level (American usage), is the stretch of level water impounded between two canal locks. Canal pounds can vary in length from the non-existent, where two or more immediately adjacent locks form a canal lock#Staircase locks, lock staircase, to many kilometres/miles. The longest canal pound in the United Kingdom is on the Bridgewater Canal between the stop lock on the Trent and Mersey Canal at Preston Brook (Dutton Stop Lock No 76) and the start of the Leeds and Liverpool Canal near Leigh (Poolstock Bottom Lock No 2), a distance of . Another long pound is on the Kennet and Avon Canal between Wootton Rivers Bottom Lock and Caen Hill top lock. The longest level on the Erie Canal in New York was the so-called '60 mile level' (actually ) between Henrietta and Lockport. History Pounds came into being with the development of pound locks to replace the earlier flash locks. A key feature of pound locks was that the intervening level between locks rema ...

Crawfish
Crayfish are freshwater crustaceans belonging to the infraorder Astacidea, which also contains lobsters. Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams, where fresh water is running, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species, such as '' Procambarus clarkii'', are hardier. Crayfish feed on animals and plants, either living or decomposing, and detritus. The term "crayfish" is applied to saltwater species in some countries. Terminology The name "crayfish" comes from the Old French word ' ( Modern French '). The word has been modified to "crayfish" by association with "fish" ( French language">Modern French '). The word has been modified to "crayfish" by association with "fish" ( American variant "crawfish" is similarly derived. Some kinds of crayfish are known lo ...

Newry
Newry (; ) is a City status in Ireland, city in Northern Ireland, standing on the Newry River, Clanrye river in counties County Down, Down and County Armagh, Armagh. It is near Republic of Ireland–United Kingdom border, the border with the Republic of Ireland, on the main route between Belfast (34 miles/55 km away) and Dublin (67 miles/108 km away). The population was 27,913 in 2021. Newry was founded in 1144 as a monastic settlement, settlement around a Cistercian abbey. In the 16th century the English dissolved the abbey and built Bagenal's Castle on the site. Newry grew as a market town and a garrison, and became a port in 1742 when the Newry Canal was opened, the first summit-level canal in Ireland. A cathedral city, it is the episcopal seat of the Roman Catholic Diocese of Dromore.

Newry Canal
The Newry Canal is an abandoned canal in Northern Ireland. Opened in 1742, it was built to link the Tyrone coalfields to the Irish Sea. The navigable route ran from Lough Neagh via the Upper Bann river to Portadown (approximated 9 miles), then approximately 20 miles from Portadown via the canal proper to Newry, terminating in the Albert Basin. The canal was closed to navigation in 1949, however its line remains intact and the towpath is currently part of the National Cycle Network and the Ulster Way long distance footpath. The Newry Ship Canal (opened in 1769), runs approximately 3½ miles south from Newry's Albert Basin to connect with the sea at Carlingford Lough. The Newry Ship Canal remains navigable by pleasure craft today. History The Newry Canal was the first summit level canal to be built in Ireland or Great Britain, and pre-dated the more famous Bridgewater Canal by nearly thirty years and Sankey Canal by fifteen years. It was authorised by the Commissioners ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hollingworth Lake
Hollingworth Lake is a reservoir at Smithy Bridge in Littleborough, Greater Manchester, Littleborough, Greater Manchester, England. It was originally built as the main water source for the Rochdale Canal, but developed as a tourist resort from the 1860s. Hotels were built around it, helped by the arrival of the railway in 1839, which brought day-trippers and weekend visitors from Manchester, Bradford and Leeds. The popularity of the lake as a resort declined in the early twentieth century and the area was used as an army camp in the First World War. The canal company sold the reservoir to Oldham and Rochdale Corporations for water supply in 1923. After the Second World War, boating rights were bought by Rochdale Council, who developed the area into the Hollingworth Lake Country Park in 1974. There has been a steady increase in facilities since, and it is now a thriving centre for water sports and other activities. Hollingworth Lake Rowing Club has been in continuous existence s ...

Pennines
The Pennines (), also known as the Pennine Chain or Pennine Hills, are a range of highland, uplands mainly located in Northern England. Commonly described as the "Vertebral column, backbone of England" because of its length and position, the range runs from Derbyshire and Staffordshire in the North Midlands, north of the Midlands to Northumberland in North East England. From the River Tyne, Tyne Gap in the north, the range extends south through the North Pennines, Yorkshire Dales, South Pennines, and Peak District to end near the valley of the River Trent. The Border Moors & Forests, Border Moors and Cheviot Hills, which lie beyond the Tyne Gap, are included in some definitions of the range. The range is divided into two by the Aire Gap, a wide pass formed by the valleys of the rivers River Aire, Aire and River Ribble, Ribble. There are several Spur (topography), spurs off the main Pennine range east into Greater Manchester and Lancashire, comprising the Rossendale Valley, Rosse ...

Rochdale Canal
The Rochdale Canal is in Northern England, between Manchester and Sowerby Bridge, part of the connected system of the canals of Great Britain. Its name refers to the town of Rochdale through which it passes. The Rochdale is a broad canal because its locks are wide enough to allow vessels of width. The canal runs for across the Pennines from the Bridgewater Canal at Castlefield Basin in Manchester to join the Calder and Hebble Navigation at Sowerby Bridge in West Yorkshire. As built, the canal had 92 locks. Whilst the traditional lock numbering has been retained on all restored locks, and on the relocated locks, the canal now has 91. Locks 3 and 4 have been replaced with a single deep lock, Tuel Lane Lock, which is numbered 3/4. History The Rochdale Canal was conceived in 1776, when a group of 48 men from Rochdale raised £237 and commissioned James Brindley to conduct a survey of possible routes between Sowerby Bridge and Manchester. Brindley proposed a route simila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pumping Station
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, Land reclamation, 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, Water supply, 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 statio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoir (water)
A reservoir (; ) is an enlarged lake behind a dam, usually built to store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aqueduct or pi ...

River
A river is a natural stream of fresh water that flows on land or inside Subterranean river, caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the Runoff (hydrology), runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their Bank (geography), banks and flood the surrounding area, spreading nutrients to the surrounding area.
