Operation of Wales' Cardiff Bay barrage is easier after an ABB upgrade of its automation control system. A £220m engineering project that took five years, the barrage is designed to regulate the level of a 500-acre lake, Cardiff Bay, by isolating it from the sea with five large sluice gates. It has three locks, one 40m X10.5m and two 40m X 8m, which allow 24-hour access to and from the bay, a step up from the earlier tide dependent bay.
