GOZ004 - Wied ta' Marsalforn 1


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 not easily accessible by the public, however it is possible from a nearby surfaced road. The dam lake covers an approximate area of 1,700m2. The purpose of this dam lake is unclear due to the absence of irrigation pipes, however it is likely it had been constructed as a flood mitigation measure. Abandoned agricultural land is present towards the western and southern region of the site, active agricultural land along the western and eastern regions and handful of residential buildings occupy the eastern and northern regions. The eastern basin of the dam lake was dominated by Eucalyptus gomphecephala. No important community habitats were noted around the dam lake.
