Adjuntas Dam
May 5, 2024
The Adjuntas Dam, located in Puerto Rico, is a gravity dam primarily used for hydroelectric purposes. Completed in 1950, this multi-arch dam stands at a height of 80 feet and has a storage capacity of 760 acre-feet, with a normal storage level of 384 acre-feet. The dam is situated on the Grande de Arecibo River and is regulated by the Puerto Rico Electric Power Authority (PREPA).
With a hazard potential rated as high and a condition assessment deemed satisfactory as of the last inspection in August 2019, the Adjuntas Dam plays a crucial role in managing water resources and generating hydroelectric power in the region. Its uncontrolled spillway has a width of 150 feet and a maximum discharge capacity of 37,500 cubic feet per second, ensuring effective flood control measures. Despite moderate risk assessments, the dam's risk management measures remain unspecified, highlighting the importance of ongoing monitoring and maintenance efforts to ensure the safety and functionality of this vital water resource infrastructure.
