The Comerio II Dam, located in Comerío, Puerto Rico, is a hydroelectric structure built in 1913 with a primary purpose of generating electricity. Standing at 128 feet tall and spanning 480 feet in length, this buttress dam harnesses the power of the La Plata River to provide a maximum storage capacity of 1825 acre-feet. Despite its impressive engineering, the dam's condition assessment is rated as poor, with a high hazard potential due to its outdated design and maintenance issues.

Managed by the Puerto Rico Electric Power Authority (PREPA), the dam is inspected every three years to ensure structural integrity and public safety. With a moderate risk assessment score of 3 on a scale of 1 to 5, the Comerio II Dam faces challenges in meeting modern safety guidelines and emergency preparedness standards. While it continues to serve as a vital source of renewable energy for the region, efforts to improve its condition and reduce potential risks are necessary to safeguard the surrounding communities and water resources.

As a key component of Puerto Rico's water infrastructure, the Comerio II Dam offers valuable insights into the intersection of water resource management and climate resilience. Its historical significance and ongoing operational challenges highlight the importance of balancing energy production with environmental conservation and safety considerations. By addressing the dam's maintenance needs and implementing risk management measures, stakeholders can ensure the long-term sustainability of this critical hydroelectric facility in the face of evolving climate conditions and water resource demands.
