Roughrigg Reservoir in North Lanarkshire is over 170 years old and has not been used as a source of drinking water since 1980.

Situated east of Airdrie and Coatbridge, with an embankment dam at the western end, the reservoir covers around 137 acres of land.

Scotland’s reservoirs are regulated under the Reservoirs (Scotland) Act 2011 and Scottish Water must now make a decision on its future.

Have Your Say

Scottish Water is asking customers to have their say on the future of the disused reservoir.

Roughrigg is a high-risk Category A reservoir which means if the dam were to fail there is a significant potential risk to people and property downstream.

Our reservoirs undergo a detailed inspection every 10 years and, in 2016, this identified Roughrigg required significant work in the interests of safety under new guidance published in 2017. This work must be carried out by 2022.


We are currently looking at options for the future of this disused asset and these include:

  • Significant works to bring it up to current required standards and whole life maintenance
  • Draining the reservoir and making a cut in the dam to an outlet channel to remove the risk of a dam failure and impact to people and properties downstream.

Keeping and maintaining the reservoir does not take into consideration any future changes to guidance or legislation, which may incur further unknown costs.

Although the site has no formal paths or boats/canoes on the water itself, the reservoir serves an active local angling club, whose members have leased the asset for fishing for a number of years.

Draining the reservoir removes the risk of dam failure and a small body of water would be retained to manage high flows in a flood event. All measures to protect the local environment and wildlife will be taken, including a fish rescue operation.

Green Environment

It also provides an opportunity to plant native Scottish woodland within the reservoir basin. This would help offset greenhouse gas emissions and supporting Scottish Water’s and Scotland’s net zero ambitions.

A woodland area could create a new green space to explore, and a haven for nature, benefitting the wider local communities.

Under the Outdoor Access Code, the area will maintain the same level of access, regardless of what course of action is taken.
