From Odiaxere to the dam, the very narrow serpentine road snakes through the irrigated valley where melons, tomatoes, maize and fig trees grow, before climbing the slopes of the Serra de Monchique with extensiveviews over the coastal chain. The vault type dam closes off the valley of Odiaxere. To the west of the dam, a reinforced conduit collects the water that supplies the electricity power station installed downstream before it is used for the irrigation of 1,800 ha of fields.
