Beniarrés Dam

Beniarrés Dam is a dam in the townships of Beniarrés, Alcosser and Planes, all located in Alicante, Land of Valencia, Spain. The dam is built on the Serpis River, and is 39 metres (128 ft) high, and has a crest length of almost 400 metres (1,300 ft).

The surface area of its reservoir reaches 268 hectares (660 acres), distributed between three municipalities, Beniarrés (22.3%), where the dam was built, Planes (64.9%), and Alcosser (12.8%). Its capacity is 27 cubic hectometres (22,000 acre⋅ft) of water, although it rarely reaches its full capacity because of the droughts caused by climate change in the region, running at around 13-14% of its capacity in 2024.
