Carraízo Dam, Gravity dam in Trujillo Alto, Puerto Rico.
The concrete structure spans 210 meters across the Río Grande de Loíza, creating a substantial reservoir that serves the metropolitan area of San Juan.
Construction of the dam began in 1950 and concluded in 1953, following initiatives by the Puerto Rico Aqueducts and Sewers Authority to support regional development.
The reservoir formed by the dam provides water resources to local communities while integrating into the landscape of Puerto Rico's northern region.
Eight floodgates regulate water levels along the dam's structure, with each gate opening to a height of 4 meters during water management operations.
The dam structure maintains a height of 44 meters with a substantial base width of 30 meters, containing 26,800,000 cubic meters of water volume.
