Safeguarding Caledonian Canal’s 200-year-old Ness Weir

The 200-year-old Thomas Telford-built Ness Weir on the Caledonian Canal is undergoing a major refurbishment as we aim to extend the structure’s lifespan by a century.

The 200-year-old Thomas Telford-built Ness Weir on the Caledonian Canal is undergoing a major refurbishment as we aim to extend the structure’s lifespan by a century.

The £2 million Scottish Government-funded project will see the weir, which sits at the mouth of Loch Dochfour and the River Ness, reinforced with 500 metres of steel piling to strengthen the structure and safeguard it for future generations. Work is currently underway, with the project scheduled to be completed by the end of October 2017.

Constructed between 1825 and 1830, the weir raises the water level of Loch Dochfour by almost two metres and Loch Ness by 1.2 metres and retains around 100,000,000m3 of water. Thanks to this elegant engineering solution, vessels are able to transit through Dochgarroch lock, through Loch Dochfour, and into Loch Ness.
