The Zillergründl Dam is an arch dam on the Ziller River in the upper Ziller Valley of Tyrol state, Austria. It lies 16 km (10 mi) east of Mayrhofen. The primary purpose of the dam is hydroelectric power generation and it supports a 360 MW pumped-storage power station. As part of the Zemm-Ziller Development, construction on the dam began in 1981 and, along with the Häusling Pumped Storage Power Plant, it was completed in 1986. The power plant was fully commissioned by 1988. The dam is the second tallest in Austria.
