Anglezarke Reservoir is the largest reservoir in the Rivington chain to the west of Anglezarke in Lancashire, England. Anglezarke Reservoir has three embankments, the longest, the Charnock Embankment is 777 metres long and 9.45 metres high, the Knowsley Embankment is 219.5 metres long and 14 metres high while the Heapey Embankment is 85.3 metres long and 9.75 metres high. It is fed by the River Yarrow, which has been diverted from its original course which is now covered by the Knowsley Embankment. It served the city of Liverpool before its current status as a supply mainly for Wigan. The original `Rivington Pike Scheme' was undertaken by Thomas Hawksley between 1850 and 1857. The scheme was to construct five reservoirs and a water treatment works at the south end of Lower Rivington with a 17-mile pipeline to storage reservoirs at Prescot. Water from two higher level reservoirs, Rake Brook and Lower Roddlesworth, was carried south in `The Goit', a channel connecting them to the reservoirs.
