URPoint Details
Bosley Reservoir is a large reservoir created to feed the Macclesfield Canal system, specifically the twelve Bosley locks. It is fed from the surrounding hills, including Bosley Cloud which rises to 1,125 feet (343 m). The canal opened on 9 November 1831.
The southern section from the Trent and Mersey Canal to the foot of Bosley locks is at 400 feet (122 m) above ordnance datum (AOD) and the locks raise the level by 118 feet (36 m) so that the summit level is at 518 feet (158 m) AOD. The reservoir had to be built at a high level, where few of the streams were sufficiently large to maintain its level. When finished the reservoir covered 86 acres (35 ha) and held 410 million imperial gallons (1,900 Ml). This was supplemented by the 92 million imperial gallons (420 Ml) held in Sutton Reservoir after that was completed in 1838.
The reservoir was surveyed in 2001 and found to be 331 million imperial gallons (1,505 Ml), around 75 per cent of the calculated volume at the time of construction.
