Castro Dam, Hydroelectric gravity dam in Zamora Province, Spain.
Castro Dam is a gravity dam on the Douro River in Zamora Province that stands 55 meters tall. The structure holds back water to drive turbines that produce electricity for regional distribution.
The dam was completed in 1946 as part of Spain's expansion of hydroelectric facilities along the Douro River. This period marked a major push to develop the country's water power resources.
The Castro Dam represents a milestone in Spanish engineering, demonstrating the integration of renewable energy facilities within the Saltos de Duero system.
This site sits in a rural part of the Douro Valley with limited public access to the facility itself. Visitors can explore the surroundings but should expect certain dam areas to be restricted for safety reasons.
The dam's position at coordinates 41.575556, -6.187222 creates a water reservoir that supports both power generation and local water resource management.
