Many thanks to The Canal and River Trust for facilitating this camera's location and capitally funding its installation. The Diglis Locks are the only pair of locks on the River Severn. The small lock is 20ft (6m) wide and 98ft (30m) long and big enough to fit 12 double decker buses.The Diglis Locks are two of the deepest of the 1,650 that British Waterways looks after.To access the Worcester and Birmingham Canal from the Severn, one must first ascend one of the two pairs of locks leading up from the river. The River Severn is the longest river in Great Britain, at about 220 miles,but the second longest on the British Isles, behind the River Shannon. It rises at an altitude of 610 metres on Plynlimon, Ceredigion near Llanidloes, Powys, in the Cambrian Mountains of mid Wales. It then flows through Shropshire, Worcestershire and Gloucestershire, with the county towns of Shrewsbury, Gloucester and the cathedral city of Worcester is a on its banks. With an average discharge of 107 m³/s at Apperley, Gloucestershire, the Severn is the greatest river in terms of water flow in England and Wales.
