Harden Beck

Harden Beck is a stream that flows from Hewenden Reservoir, over Goit Stock Waterfall to the River Aire in Bingley, West Yorkshire. The route starts out further up the valley as Denholme Beck, Hewenden Beck and Hallas Beck. Its waters are fed by Thornton Moor Reservoir, Stubden Reservoir, Doe Park Reservoir and Hewenden Reservoir.

Harden Beck is an overflow channel of Glacial Erosion which was carved out during the last ice age. The section after the waterfall down to the bridge under the road to Wilsden, is locally referred to as 'The Hidden Valley.'

Mapping lists Harden Beck as starting where Hallas Beck and Cow House Beck meet, but documents from Bradford Council and the Yorkshire Invasive Species Forum list the beck as starting at the dam head from Hewenden reservoir

In his book, Chronicles of Old Bingley, Harry Speight says that the Beck does start at the confluence of Hallas and Cow House Becks and that Harden Beck was a dividing line in the parishes, deaneries and the Wapentakes.
