Cardiff Bay is the area of water created by the Cardiff Barrage in south Cardiff. The creation of the Bay is now widely regarded as one of the most successful regeneration projects in the United Kingdom. The Bay is supplied by two rivers (Taff and Ely) to form a 2.0 km2 freshwater lake around the former dockland area south of the city centre. The Bay was formerly tidal, with access to the sea limited to a couple of hours each side of high water but now provides 24-hour access through three locks.
