Title: River Usk barrage position statement, 6th February 1992
Author: National Rivers Authority Welsh Region
Document Type: Monograph
Abstract:
Newport Borough Council propose to construct a barrage across the river Usk Estuary at Newport thereby creating a body of impounded water some 11 kilometres in length, with a minimum retained water level. The existing estuary is a highly dynamic system throughout its entire length, from the tidal limit near Newbridge-On-Usk to the confluence with the Severn Estuary at Newport. Because of the high tidal range and the fast tidal currents the Usk Estuary is a well mixed, non-stratified body of water displaying a gradual change in salinity from the saline water of the Severn to the fresh water of the Usk river. Following construction of the barrage, the impounded waters would be transformed into a lake which will be affected by freshwater river flow and the controlled intrusion of saline water.
