Site description Potworks Dam IBA is in south-east Antigua, c.2 km north of the village of Bethesda and Bethesda Dam IBA (AG012). The reservoir dam was under construction in 1969 when the area flooded as a result of exceptionally heavy rains. The dam site filled with water before preparation of the site was finished, but is considered a municipal reservoir and is an important source of water for domestic and agricultural use. Due to the very shallow sides to the reservoir and frequent droughts, the shoreline fluctuates greatly over time, reducing opportunities for the establishment of aquatic vegetation. Land surrounding most of the reservoir is former sugar cane estate land that is now farmed or grazed (primarily by free-roaming cattle).
