Matrullas Dam, located in Ciales, Puerto Rico, is a vital piece of infrastructure owned by the Puerto Rico Electric Power Authority. Constructed in 1934, this earth dam stands at a height of 120 feet and spans 710 feet in length, harnessing the power of the Matrullas River for hydroelectric and irrigation purposes. With a storage capacity of 3,590 acre-feet and a maximum discharge of 15,000 cubic feet per second, the dam serves as a crucial water resource for the surrounding region.

Despite its significant contributions, Matrullas Dam poses a high hazard potential and has been assessed as having an unsatisfactory condition. The dam is regulated by PREPA and undergoes regular inspections to ensure its safety and integrity. With a drainage area of 4.42 square miles and a surface area of 77 acres, the dam plays a crucial role in managing water resources in the region. Its uncontrolled spillway and stone core structure highlight the engineering complexities involved in maintaining this essential infrastructure.

As climate change continues to impact water resources worldwide, the importance of structures like Matrullas Dam cannot be overstated. With a risk assessment rating of moderate, the dam's risk management measures are continuously evaluated to mitigate potential hazards. As a key player in both water supply and renewable energy generation, Matrullas Dam stands as a testament to the intersection of water resource management and climate resilience in the face of evolving environmental challenges.
