Cardiff Barrage

The Cardiff Barrage lies across the mouth of Cardiff Bay, Wales between Queen Alexandra Dock and Penarth Head. It was one of the largest civil engineering projects in Europe during construction in the 1990s.

History
The concept of a barrage was first suggested in the 1980s as a way to help regenerate Cardiff's largely disused docklands. The barrage would create a large freshwater lake intended to attract investment into the docklands. The bay was part of the Bristol Channel which has the second largest tidal difference in the world. As a result, for half of the day, the bay was empty of water, leaving large unappealing mudflats exposed. The barrage was consequently seen as central to the regeneration project. The government established the Cardiff Bay Development Corporation to build the barrage, and to redevelop the area as a whole.
Opposition
Opposition to the project came from many quarters. Some local politicians (including the area's MP, Rhodri Morgan, now First Minister of the Welsh Assembly) said the scheme would cost too much money. Local residents feared that their homes would be damaged by the permanently raised water level. Environmental groups strongly opposed constuction because the bay was an important feeding ground for birds, which would be lost following impoundment.
Construction
Construction started in 1994, following the successful passage of the Cardiff Bay Barrage Act through the UK Parliament. The bill included provisions for compensation for any homes damaged by the barrage and a large wetland habitat for birds further east down the Bristol Channel. Features include a fish pass to allow salmon to reach breeding grounds in the River Taff and three locks for maritime traffic. Construction was completed in 1999 and shortly afterwards the barrage came into effect. The impounding of the the River Taff and River Ely created a 2km² (500 acre) freshwater lake.
Today
The barrage has played an important role in the area's regeneration. Attractions such as the Wales Millennium Centre, the National Assembly for Wales, a sports village, shopping and watersports have since moved onto the waterfront. In 2000 the Cardiff Bay Development Corporation was dissolved, and the Welsh Assembly awarded a contract to Cardiff County Council to manage the barrage.
