The Shannon–Erne Waterway (Irish: Uiscebhealach na Sionainne is na hÉirne; Ulster-Scots: Shannon–Erne Wattèrgate) is a canal linking the River Shannon in the Republic of Ireland with the River Erne in Northern Ireland. Managed by Waterways Ireland, the canal is 63 km (39 mi) in length, has sixteen locks and runs from Leitrim village in County Leitrim to Upper Lough Erne in County Fermanagh.

The official opening of the Shannon–Erne Waterway took place at Corraguil Lock, Teemore, County Fermanagh on 23 May 1994.


The grand plan of linking the river systems of the Erne and the Shannon with Lough Neagh was behind the planning for several of the Irish canals, and the first attempt at a link between the Erne and the Shannon was made in 1780, along the Woodford river, from Belturbet to Ballyconnell. Richard Evans carried out the work, which was financed by a grant of £1,000 from parliament. He built a lock near Carrowl, but failed to obtain any more grants, and the project ceased. In 1790, there was a scheme to connect Lower Lough Erne to the sea at Ballyshannon, which would involve the construction of twelve locks, but only one was built,[1] and the scheme foundered in 1792, due to a failure to raise enough capital.[2]

The next survey of the Woodford river was made in 1793 by William Chapman, who estimated that Garadice Lough could be reached for £5,000, from where he believed that a link to the Shannon should be possible. Eight years later, the Directors General asked Richard Evans, who had carried out the work in 1780, to estimate the cost of a link from the Shannon to the Erne, and also to reappraise the link from the Lower Erne at Belleek to the sea at Ballyshannon. Evans estimated that the two projects would cost £48,000, but the Directors General took no action, and this was the last time that the link to the sea was considered.[3]

In 1838, the Commissioners of Public Works were created, and one of their tasks was to find public schemes that would create employment. Accordingly, William Mulvany carried out the next survey at their request, at a time when work had begun on the Ulster Canal, which would provide the link onwards to Lough Neagh. The powers of the Commissioners were increased in 1842, so that their remit included navigations, drainage and water power works. The Ulster Canal wanted the link to the Shannon completed, while local landowners wanted better drainage of the area, and these two factors finally convinced the Commissioners that they should act. The scheme would combine navigation and drainage, and plans were drawn up by John McMahon, an engineer working for the Board of Works. He estimated that the work would cost £100,000.[4]

When work began on the Ballinamore and Ballyconnell Canal in 1846, it was financed by the Office of Public Works with John McMahon setting out the line and William Mulvany acting as the engineer in charge.[2] The mix of drainage and navigation was always an awkward combination, since the first required low water levels and the second required high water levels. The engineering would have been simpler if two separate schemes had been built, as would the finances, since the drainage work had to be accounted for separately, and there were often delays while waiting for funding which was part of the other scheme. There were also problems with millers and eel fisheries, and surprisingly for a scheme designed to provide employment, difficulty with finding sufficient numbers of labourers to carry out the work. At the start of the project, over 7,000 were employed, but this reduced to 2,500 in its later stages.[4]

A navigation channel was dredged through the six loughs which formed part of the canal using steam dredgers. The locks down to Lough Erne were all constructed with large weirs, and there were considerable problems with flooding from the Woodford River during construction. Between Lough Scur and Leitrim, the Leitrim River was enlarged, and eight locks were built. It soon became obvious that the original estimates were totally inadequate, and in 1852 there was an investigation into the Board of Works, since they seemed unable to deliver any projects within budget. Mulvany became the scapegoat, and was blamed for the overrun. He made cutbacks, reducing the depth from 6 feet (1.8 m) to 4.5 feet (1.4 m), although in places the navigation was shallower than this. Despite the stringency, towpaths were built on the canal sections at huge cost, even though the loughs made it impossible to use horse power for much of the distance, and boats with steam engines were already working on the Shannon.[5]

The first boats to use the canal from Ballinamore began to do so in 1858. By 1859 the cost had risen to £276,992, and there was a dispute as to who should pay the difference between that and the original estimate. Following a public enquiry, £30,000 was paid by each of the counties through which the canal ran, and the rest was funded by the government. Management was to be by a group of navigation trustees and a separate group of drainage trustees, which again provided conflict. The canal was handed over to them on 4 July 1860. Within months the engineer and secretary of the trustees, J. P. Pratt, had compiled a long list of problems. The records showed that only eight boats used the canal between 1860 and 1869, generating tolls of £18, and with this level of usage, there was little incentive to put things right.[6]


Two enquiries held at the time give an insight into the canal. The Crighton Committee of Enquiry was set up in 1878 to investigate the performance of the Board of Works, and following their findings, the Monck commission looked at the issues of a route from Belfast to Limerick. As part of the evidence collected, Pratt related that he had ceased to maintain it after 1865, since there was no traffic, and John Grey Vesey Porter, one of the trustees, described a three-week journey along the canal in a steamer in 1868, which had only been achieved by Pratt moving the water from pound to pound to keep the boat afloat. He declared the whole project to be one of the most shameful pieces of mismanagement in any county. In 1887, the Cavan and Leitrim Railway arrived in the area, and were sufficiently confident that the canal would not be used that they built low bridges over it, preventing navigation. The railway was not a commercial success either, and was another drain on local resources.[7]

The Shuttleworth Commission recommended that the upper lock gates should be repaired in 1906, to prevent further damage to the structures of the waterway, but with no funds available, the navigation trustees concentrated on minor bridge repairs, to keep landowners and local authorities happy, and by 1948 they had ceased to function. Local authorities had to assume responsibility for bridge repairs, and there were ongoing problems with flooding.[8]

A new waterway

The canal lay moribund until the 1960s, when the growth in pleasure boating on the Shannon led enthusiasts to consider whether it could be restored. By 1969, Leitrim Council and the Inland Waterways Association of Ireland were asking for a full survey to be carried out.[10] Here things lay until 1988, when an engineering and feasibility study, funded by the International Fund for Ireland, examined the issues surrounding reinstatement of the canal, which lay across the border between the Republic of Ireland and Northern Ireland. In June 1989, Charles Haughey, the Taoiseach, announced that the two governments had decided to adopt the proposal as a flagship cross-border project. In order for the project to take place, the powers of the original trustees, which had passed to the local authorities along its route, were transferred to the Office of Public Works. Work commenced in November 1990 and the canal was opened to traffic on 23 May 1994 on time and within the budget of £30m. It was essentially a new navigation along the line of the original waterway, which had never been properly completed in the first place.[11]

The work involved major reconstruction of many of the structures, to make them suitable for modern cruisers. The eight locks between Lough Scur and Lough Erne were new concrete structures, and were widened to 19.8 feet (6 m), but were faced with stone from the original locks. The eight locks down to the Shannon were in better condition, and were repaired, so retain their original width of 16.5 feet (5 m). The locks are fully automatic, and are operated by the boat crews, using a smart card to activate the control panel, although they can only be used when waterways staff are working. Once restored, the canal was renamed, becoming the Shannon–Erne Waterway, to reflect its purpose of linking the two river systems, and it was opened by Dick Spring, the Irish Foreign Minister and Sir Patrick Mayhew, the Secretary of State for Northern Ireland at the time. One unfortunate result of the scheme has been the invasion of the Erne system by the zebra mussel, a non-native species which travelled along the waterway from the Shannon.[12]

Course of the waterway

The waterway has three natural sections: a still-water canal from the Shannon at Leitrim to Kilclare, which has eight locks; a summit level which includes Lough Scur, and a river navigation from Castlefore, near Keshcarrigan, through Ballinamore and Ballyconnell to the Erne, which has another eight locks.[13]
