The Aire and Calder Navigation is a river
River

s, from which coal was unloaded into ships by large hydraulic hoists. This system enabled the canal to carry over 1.5 million tons of coal per year at its peak, and was not finally abandoned until 1986. In order to handle trains of compartments, many of the locks were lengthened to 450 feet (137.2 m).

Although much of the upper reaches are now designated as leisure routes, there is still significant commencial traffic on the navigation. 300,000 tons were carried in 2007, although most of the traffic is now petroleum and gravel, rather than the coal which kept the navigation profitable for 150 years.

History

In the early 1600s, the river Aire was navigable to Knottingley, and boats carrying up to 30 tons traded on the river, which was tidal up to this point. The traders of Leeds were keen to have a navigable link to the town, to make the export of woollen cloth easier, but bills presented to Parliament in 1621 and 1625 had failed. William Pickering, who was mayor of Leeds, had made further attempts to obtain an act of Parliament

 for improvements to the river in 1679, again without success, but as the 1600s drew to a close, a number of bills were passed for other rivers, and there was general support for river navigations. A bill was drawn up in 1698, with support from wool traders in Leeds and general merchants in Wakefield. John Hadley surveyed the Aire, and Samual Shelton surveyed the Calder. Although the bill had a lot of support, it was opposed by the City of York, who feared that the River Ouse

s. John Hadley was engaged as the engineer immediately, and by 1704 the original work was completed, including 12 locks on the Aire between Haddesley and Leeds and 4 on the Calder. The locks were 58 to 60 ft (17.7 to 18.3 m) long by 14.5 to 15 ft (4.4 to 4.6 m) wide with 3.5 feet (1.1 m) depths over the sills.

Capital to fund the scheme had been raised separately by the Wakefield and Leeds committees. A complicated restructuring of the finances in 1721 fixed the nominal capital at £26,700. Regular dividends at 7 per cent were paid to the shareholders from 1718, and the navigation was leased to various groups, who would be responsible for collection of tolls and repairs. The lease rose from £800 in 1704 to £2,600 in 1729, when receipts from each of the previous five years had averaged £6,016.

 travelling in the opposite direction. By the 1720s there were also significant quantities of coal.

Development

Some development of the navigation occurred. In 1744, the undertakers bought some land at Airmyn, and developed warehousing and wharfage there, as a more convenient point than Rawcliffe, where the water was shallower. In the 1760s, £13,000 was spent on improvements and maintenance, with several weirs being rebuilt to improve the depth of water. There was a long-running dispute with Arthur Ingram, who owned Knottingley mill, which started in 1731, and was not finally resolved until 1776, when the company bought both of Ingram's mills. Despite this, the general profitability of the navigation led the undertakers to be complacent about its development. The asked John Smeaton

 was not, as the company bought the mill there instead. All locks were replaced, and the total cost was over £60,000, of which around £20,000 was for the Selby Canal. The navigation remained profitable, paying £9,000 in dividends in 1775, which had risen to £32,000 by 1791. Most traffic now used the Selby route, and the transhipment facilities at Airmyn were closed in 1779.

Selby was the upper limit for sea-going ships at the time, and became a major transhipment port for the smaller boats using the canal. Canal boats were limited to about 60 tons, whereas ships of up to 200 tons could reach Selby. By 1800, it was handling some 369,780 tons of goods, and the support industries of ropemaking, sailmaking and shipbuilding were expanding.

, and John Rennie was asked to survey the route. Those opposing the scheme were placated by a clause which ensured the Aire to Airmyn and the Selby Canal would be maintained. In July 1821, Rennie proposed the construction of docks at Goole, rather than a lock into the river, and the company proposed that 7 feet (2.1 m) of water should be available. Rennie died in late 1821, and George Leather took over as engineer. Construction at Goole started on 28 September 1822, and the company eventually built much of the new town as well as the docks.

The canal and docks opened on 20 July 1826. A barge lock, 72.5 by and a ship lock, 120 by, capable of taking vessels up to 400 tons, connected the extensive docks to the Ouse. The new section was 18.7 miles (30.1 km) long, with locks at Ferrybridge

 and Goole. The connection to the Aire and the Selby canal was maintained by the lock at Bank Dole. Goole became an official port in 1827, when it gained its own Customs facilities. The scheme had cost £361,484, of which £221,350 had been borrowed, while the rest came from company resources.

Faced with yet another outside scheme which would bypass the navigation from Wakefield to Ferrybridge, the company looked at improvements which would give 7 feet (2.1 m) of water all the way to both Leeds and Wakefield. Thomas Telford

 surveyed both routes, and it became the basis for an act of Parliament which was passed in June 1828. It included a clause to ensure that the Selby Canal was maintained with a depth of water of 5 feet (1.5 m), and made provision for extensions to Goole docks. Work started on a new cut at Castleford and on the line to Leeds, but legal action over the Selby Canal meant that it had to be made deeper and wider in 1832 and 1833. The Leeds line was completed in April 1835, somewhat later than anticipated, as the banks were made more substantial, in order to cope with steam tugs, which would be introduced in due course. The seven locks above Castelford were all 18 feet (5.5 m) wide. Improvements to the Calder to Wakefield took longer, as there were problems with floods filling the workings, difficulty with constructing foundations for an aqueduct which would carry the navigation over the River Calder at Stanley Ferry

, and then in transporting the castings for the aqueduct to the site. The cost of the improvements ran to around £510,000.

Modernisation

The Aire and Calder tried to work with the railways when they arrived in the 1840s, by making traffic agreements, but still suffered a significant drop in trade. Receipts dropped by one-third between 1851 and 1856. Thomas Hammond Bartholemew, the chief engineer, had been experimenting with steam power since 1813, and steam paddle tugs had been operating on the system since 1831. When he died in late 1852, two-thirds of the traffic was pulled by steam tugs. His son, William Hamond Bartholomew

, carrying 700 tons, but were held up at locks, as the keels had to be worked through one at a time. Between 1860 and 1867, the locks from Goole to Castleford were extended to 206 by to alleviate this.

In 1861, Bartholomew met with the chairman, Warde-Aldam, to propose a system of sectional boats, each consisting of six compartments, with a bow and stern section. The compartments or tubs would be unloaded into ships by a hydraulic hoist at Goole, which would lift them from the water and tip them over. Warde-Aldam thought that such a system could carry 45,000 tons of coal per year, and £13,382 was allocated for three train boats, a hoist, and hydraulic machinery to control the hoist and the lock into the docks. By late 1864, the prototypes were operational, with the stern section replaced by a pusher tug

Tugs move vessels that either should not move themselves, such as ships in a crowded harbor or a narrow canal,or those that cannot move by themselves, such as barges, disabled ships, or oil platforms.

The length of the trains increased to ten or eleven tubs, but such a train was difficult to steer from the rear, and so the tugs moved to the front and pulled the assembly. In 1880 they carried 151,860 tons, and by 1913 there were 18 tugs, 1,010 compartments, and 1,560,006 tons were carried, 33 times Warde-Aldam's original estimate.
After the First World War, another programme of improvements to the locks was carried out, extending the locks to 457 feet (139.3 m), which enabled trains of 19 compartments to operate regularly. Experiments with trains as long as 38 tubs were carried out, but the difficulty of splitting the train to pass through the locks meant that 19 was the usual maximum. The compartments were still being used to carry around half a million tons of coal until the late 1960s, long after most British canals had ceased to be used for commercial traffic, but the gradual demise of the coal industry led to compartment traffic ceasing in 1986.

The 20th century saw two major phases of improvement. In 1905, the New Junction Canal

 near Stainforth. It was funded by the Aire and Calder, with the Don Navigation eventually meeting half the cost. During the 1960s, the navigation underwent another modernisation scheme, in which the locks from Goole to Leeds were upgraded and enlarged to accommodate vessels conforming to the 700-tonne Euro-barge standard. There is some variation in lock sizes, with the smallest being at Knostrop, which is 203 by with a water depth of 8.4 feet (2.6 m) over the lock cill. Euro barges are 200 by, and when fully loaded with 600 tonnes of cargo, have a draught of 8.2 feet (2.5 m). Locks on the Wakefield section can accommodate vessels which are 141 by with a draught of 7.5 feet (2.3 m), while the locks below Castleford have three sets of gates, so that a 200 feet (61 m) section can be used, rather than the full 457 feet (139.3 m) required by the compartment boats.

The main problem with upgrading the Wakefield branch was the dimensions of George Leather's cast iron aqueduct over the River Calder at Stanley Ferry. Structural analysis showed that parts of the ironwork were overloaded, and so in 1981 a new concrete aqueduct was cast by John Laing Construction Ltd, on a site a little further upstream. The complete structure was then pushed into position by hydraulic jacks in a six-day operation, after which the navigation was diverted over it, although the old aqueduct was left in place and can still be used.

Although coal mining was one of the main reasons for the success of the navigation, it has also brought problems, caused by subsidence. In March 1988, the bank near Lemonroyd lock collapsed into St Aidens opencast mine, which then flooded. A significant factor was the presence of excavations below the opencast workings where lower coal seams had previously been mined. The failure resulted in some 780000 cubic yards (596,352.8 m³) of material, including the banks of the river and the canal, slipping into the workings, which then flooded to a depth of 230 feet (70.1 m), creating a lake which covered 250 acres (101.2 ha). An act of Parliament was obtained to allow 1.9 miles (3.1 km) of new waterway to be constructed. The original locks at Kippax

 and Lemonroyd were replaced by a single lock at Lemonroyd. Opencast mining finally resumed ten years later, after the site had been pumped out, but the coal reserves are now exhausted, and the site forms a nature reserve, with wet grasslands, reedbeds and open water covering 740 acres (299.5 ha).

Traffic

A 20th century modification of the compartment boat system was used to feed the coal-fired Ferrybridge

 "C" power station. Starting in 1967, Cawoods Hargreaves used trains of three tubs or coal pans, which were rigidly connected, and pushed by a tug when loaded. The trains were filled with coal using canalside chutes at the colliery and pushed to the power station, where a hoist lifted each pan from the canal and upturned it to drop it contents onto a conveyor belt. Nine tugs and 35 pans were employed, with each pan holding around 170 tonnes. By the time the final load left Astley colliery in December 2002, 43 million tonnes had been delivered to Ferrybridge in this way. Experiments were made with trains of four pans, which allowed copper pipes to be carried on top of the coal for delivery to Goole, but this was short-lived. Coal carrying came to an abrupt halt during the late 20th century when the St Aidens opencast mine was exhausted and the coal from Kellingley colliery was found to have levels of sulphur content way above the acceptable limit. During 2008, three of the trains were used on the River Don, to transport 250,000 tonnes of limestone from a quarry at Cadeby to Hexthorpe.

British Waterways introduced a similar system in September 1974. Called BACAT, for Barges Aboard Catamaran, the system consisted of trains of barges, which were pushed by a tug, and which would be loaded between the twin hulls of a custom-built delivery ship. The ship would then transport them across the North Sea to continental waterways, without their contents having to be transshipped. The concept failed after 18 months, as the dock workers at Hull blacklisted the entire British Waterways fleet, because they believed that the system would threaten their jobs. Most of the commercial traffic using the navigation now consists of petroleum tankers and gravel barges.

Leisure boating

The Aire and Calder was built for commercial freight, and although the volume carried has dropped significantly, particularly since coal deliveries to Ferrybridge power station by canal stopped, the navigation still carried 300,000 tonnes of freight in 2007, down from 1.64 million tonnes in 2000. The Leeds to Castleford section and much of the Wakefield branch are now designated as leisure routes, but below Castleford, the industrial nature of the waterway is more obvious, and pleasure boats must give way to commercial vessels. 700 tonne vessels, designed to make maximum use of the locks, produce considerable wash, and are not as manoeuvrable as a narrow boat.

Much of the ex-industrial (western) part of the Navigation now has the appearance of a tree-lined, gently-twisting river. The eastern part of the Navigation, sometimes known as the Knottingley and Goole Canal, is rather different: it has long straight stretches, but mainly through flat land that has always been agricultural. Between Wakefield and Leeds, via Castleford, the navigation is part of a circular cruising route or "ring", formed by the Leeds & Liverpool and the Huddersfield
