Yahuecas Dam, located in Adjuntas, Puerto Rico, is a gravity-type dam primarily used for hydroelectric power generation. Built in 1956, this impressive structure stands at a height of 90 feet, with a storage capacity of 2400 acre-feet and a surface area of 55 acres. The dam serves multiple purposes including hydroelectric power generation, irrigation, and water supply for the surrounding area.

Managed by the Puerto Rico Electric Power Authority (PREPA), Yahuecas Dam is a crucial water resource infrastructure in the region. With a high hazard potential due to its location on the Rio Blanco river, the dam is regularly inspected and maintained to ensure its structural integrity and safety. Despite its age, the dam's condition is assessed as satisfactory, with a moderate risk level of 3 indicating a need for ongoing risk management measures.

The dam's impressive engineering and strategic location make it a key resource for water management and climate resilience in Puerto Rico. With its ability to generate clean energy and provide water for various uses, Yahuecas Dam stands as a testament to the importance of sustainable water resource management in the face of changing climate conditions.
