Garzas Dam, also known as Lago Garzas, is a vital water resource structure located in Adjuntas, Puerto Rico. Owned by a public utility, this dam serves multiple purposes, including hydroelectric power generation and water supply. Completed in 1943, the dam stands at a height of 201 feet and has a maximum storage capacity of 5,500 acre-feet, providing essential water resources for the surrounding area.

Situated on the Vacas River, Garzas Dam is regulated by PREPA and falls under the jurisdiction of Puerto Rico. With a high hazard potential and an unsatisfactory condition assessment as of May 2019, the dam poses a moderate risk that requires ongoing monitoring and risk management measures. Despite its challenges, the dam continues to play a crucial role in water management and climate resilience efforts in the region.

As a key infrastructure for both water supply and hydroelectric power, Garzas Dam represents a critical component of Puerto Rico's water resource management system. Efforts to address the dam's risk factors and ensure its continued operation are essential for safeguarding water access and energy generation in the region. For water resource and climate enthusiasts, Garzas Dam serves as a poignant example of the complex challenges and opportunities involved in managing water infrastructure in a changing climate.
