Happy Jacks Dam, Gravity dam in Kosciuszko National Park, Australia.
Happy Jacks Dam stretches 76 meters across the Tumut River, featuring a concrete wall that rises 29 meters high in the Snowy Mountains region.
The dam was completed in 1959 as part of the Snowy Mountains Scheme, a major hydroelectric and irrigation project constructed between 1949 and 1974.
Engineers from the United States Bureau of Reclamation collaborated with Australian authorities to design this structure within the Snowy Mountains landscape.
The reservoir holds 271 megalitres of water and includes an uncontrolled spillway capable of discharging 1,827 cubic meters per second.
The dam's construction required 8,950 cubic meters of concrete and created a 5-hectare pondage that supports regional hydropower generation.
