Mill Beck (Poaka Beck)
Mill Beck was used as the water source for Furness Abbey, which was founded in 1123 AD. As well as providing water for drinking, the beck also provided the water power for a mill downstream of the Abbey. The beck flows through Barrow-in-Furness, where it discharges into Cavendish Dock and the Irish Sea. Mill Beck is formed at the confluence of Goldmire Beck with Poaka Beck, at Dalton-in-Furness. Poaka Beck Resevoir forms part of the water body; which has a catchment area of 23.3 km2 and is 17.6 km long (Mill Beck and Poaka Beck combined).
