Parkhead Lock Flight on the Dudley No.1 Canal, locks down from the 73km Wolverhampton Level onto the Birmingham Level. The water is mainly supplied by Chasewater Reservoir and Bradley Pumps.
Chasewater (Cannock Chase) Reservoir, is the Trust's largest reservoir with a capacity of over 4,500 million litres.
Bradley Pumps lift groundwater from the coal measure at Bradley, in Wolverhampton.
Water from Chasewater Reservoir is transferred to Parkead Locks along the Anglessey Branch, Wyrley & Essington and Old Main Line Canals on one level.
The Titford Canal, also provide lockage water, topping up supplies to this level. Feeders also bring water into the canal.
When the canals were built water as already being pumped out of the coal mines so it was logical to use it in the canals. The Trust can pump up to 32 million litres of water per day at Bradley.
