GOZ006 - Wied ta' Marsalforn 2


Wied ta’ Marsalforn is an artificial dam lake constructed within Wied ta’ Marsalforn, located in northern Gozo within the limits of Marsalforn. The site is easily accessible by the public from a nearby surfaced road. The dam lake covers an approximate area of 3,290m2. No irrigation pipelines were present throughout the site, thus it is likely the dam lake is not used for irrigational purposes. It is likely the dam had been constructed as a flood mitigation measure for the nearby surfaced road. The site is predominantly surrounded by active agricultural land with a handful of abandoned fields scattered nearby. A population of Discoclossus pictus was present throughout the site alongside Rumex conglomeratus, Arum italicum and Tamarix sp. The site is not protected by any legislation.
