Melania Dam, located in Juana Díaz, Puerto Rico, was completed in 1914 and serves as a vital irrigation source for the region. Managed by the Puerto Rico Electric Power Authority, this earth dam stands at 30 feet tall with a length of 1200 feet, holding a maximum storage capacity of 456 acre-feet. The dam is situated on Melania Creek, with a spillway width of 27 feet and a maximum discharge of 680 cubic feet per second.

The dam's hazard potential is rated as high, but its condition assessment is deemed satisfactory as of the last inspection in December 2021. With a risk assessment of moderate, measures for risk management are yet to be fully detailed. The dam's primary purpose is irrigation, highlighting its significance in sustaining agricultural activities in the area. Despite its age, Melania Dam continues to play a crucial role in water resource management and climate resilience efforts in Puerto Rico.

Water resource and climate enthusiasts can appreciate Melania Dam for its historical significance, engineering design, and impact on local ecosystems. As a state-regulated structure with state permitting, inspection, and enforcement protocols in place, the dam represents a collaborative effort to ensure public safety and water security. With ongoing risk assessments and management measures, Melania Dam serves as a reminder of the importance of sustainable water infrastructure in mitigating the effects of climate change and supporting community resilience in the face of environmental challenges.
