GOZ013 - Wied tal-Ort


Wied ta’ l-Ort is a valley with numerous artificially constructed dams, located in central Gozo, within the outskirts of Rabat. The site is not accessible by the public as there are no passageways or footpaths available, however, the dam lakes are visible from a nearby surfaced road. The dam lakes cover an approximate area of 5,800m2. Culverts present within the road indicate the dam lakes are filled by water runoff thus being utilized as a flood mitigation measure. The water collected within the dam lakes are being used for irrigation purposes due to pipelines emerging from nearby agricultural land. The site was dominated by Persicaria senegalensis and Ricinus communis. The site is not protected by any legislation.
