The Story of Lake Lyell: Powering the Present, Preserving the Past
Tucked away in the rolling landscapes of New South Wales, Lake Lyell may look like a serene natural wonder — a peaceful retreat for boating, fishing, and weekend escapes. But behind the calm waters lies a fascinating story of engineering, energy, and environmental responsibility.
Not Nature-Made — But Carefully Created
Despite its natural beauty, Lake Lyell is entirely man-made. Back in 1982, the NSW Government’s then-owned Delta Electricity built the dam that would give rise to the lake. The goal? To create a reliable water source for the Mt Piper and Wallerawang Power Stations.
The construction of the dam flooded parts of the Coxs River and Farmers Creek, forming the lake we know today. And Lake Lyell didn’t stand alone — it became part of a connected system that includes Thompson Creek Reservoir and Lake Wallace, working together to support regional energy generation.
More Than Just a Pretty Place
While Lake Lyell is now popular for recreation and tourism, it remains a critical asset for infrastructure and energy operations. Today, EnergyAustralia owns and operates the lake, as well as its companion reservoirs and dams — including Lilyvale Dam and Thompsons Creek Reservoir.
Managing a system like this doesn’t come easy — or cheap. EnergyAustralia invests over $2.5 million every year into the ongoing maintenance and compliance of Lake Lyell alone. From structural upkeep to environmental monitoring and community engagement, these efforts ensure the lake remains safe, sustainable, and ready for the future.
Sustaining the Future of Our Water Systems
Lake Lyell is a great example of how energy and environmental stewardship can coexist. It’s not just about powering homes and industries — it’s about protecting the ecosystems and communities that rely on these waterways.
As we move into a future focused on cleaner, more efficient energy, maintaining and upgrading our existing infrastructure will be just as important as building new solutions. Thanks to continued investment and responsible management, Lake Lyell is well-positioned to keep playing its part — both as a source of energy and a beloved local landmark.
