Lyell Dam

Owner : Delta Electricity

Two serious ruptures of the inflatable dam led the operator to seek a more robust solution to maintain the same fill level of the reservoir without reducing its discharge capacity.

Straight-crested fusegates were selected as they are specially designed to function effectively under strong headwaters.

They were built on-site with cast reinforced concrete and weigh over 120 tons apiece.
