Located at the outlet of Lake Hāwea, the Hāwea Dam is a zoned earth embankment structure built in the 1950s. It plays a vital role in New Zealand’s hydroelectric network by providing controlled water storage for the Clyde and Roxburgh power stations.
Without this regulation, these stations would rely solely on natural river flows, which can vary significantly with seasonal and weather conditions. The dam includes sluice gates that release water as needed, helping to maintain consistent generation capacity.
