The dam's reservoir has a total capacity of approximately 379 million cubic meters.
The village of Aceredo, flooded in 1992, frequently emerges when reservoir water levels drop during prolonged droughts.
The dam features a double-curvature arch design common in high-pressure hydroelectric installations.
It is a key component in the Portuguese-Spanish transboundary water management agreement for the Lima River basin.
The Alto Lindoso Dam is the tallest concrete dam in Portugal, standing at 104 meters high. Located in the Peneda-Gerês National Park, it functions as a hydroelectric power plant on the Lima River. The dam facilitates a reservoir that occasionally reveals the ruins of Aceredo, a village submerged during the dam's construction in 1992. This site functions primarily as a piece of large-scale civil engineering infrastructure rather than a traditional tourist attraction. The reservoir's water levels fluctuate significantly based on seasonal hydroelectric demand. Access is situated near the border with Spain, allowing for views of the surrounding mountainous landscape. The structure is operated by EDP (Energias de Portugal).

Check recent weather reports or local news regarding water levels if you hope to see the submerged village ruins.
Bring binoculars for spotting wildlife in the surrounding Peneda-Gerês National Park.
Maintain caution on the narrow, winding mountain roads leading to the dam area.
Do not attempt to walk on the dam structure itself, as it is a secure industrial facility.
No specific dress code, but sturdy, closed-toe walking shoes are recommended due to uneven terrain.
