- Tad-Dawl

Tad-Dawl is artificially constructed reservoir, intended for irrigation and water storage, located in southern Malta within Marsaskla. The reservoir has been constructed from limestone and covers an area of approximately 1,090m2. The site is accessible to the public through a dirt road or pathway although it was noted that, it is located on privately-owned property. The site is predominantly surrounded by agricultural land and is likely used for irrigation purposes due numerous pipelines emerging from the reservoir. Within the reservoir, a large population of Lemna minor L. is present. The site is not protected by any legislation.
