English: East Aberthaw lagoon This area, at the estuary of the River Thaw was once a busy port. The landscape was substantially altered by the building of Aberthaw Power Station when the river was straightened and the estuary became a tidal lagoon. Much of the nearby area is covered by ash from the station but it remains a site of importance for wild life. Since the tip was extended in the late '80s the reed beds have begun to regenerate and are now used by both Reed and Sedge Warblers. An Aquatic Warbler was trapped and ringed here, also in the '80s, and the reed beds served as roosts for Whinchat, Reed and Sedge Warbler, Kingfisher, Swallow and Yellow Wagtails and it is to be hoped that they, as well as other species that once used the area, might well be seen again as the area develops further.
