- It-Tghatigha

It-Tghatigha is an artificially constructed reservoir, intended for irrigation and water storage, located in southern Malta within Santa Luċija. The reservoir is constructed out of cement and covers an approximate area of 1,630m2. The site is accessible by a surfaced road, however, the reservoir itself is fenced off. Surfaced roads are located to the north and west of the reservoir, with an abandoned field to the east and active agricultural land to the south indicating that the reservoir is likely being used for irrigation. The site has no vegetation present within the border, however, it is located close to Wied ta’ Garnaw. Within the reservoir, a large population of Lemna minor L. is present. The site is not protected under any legislation.
