Hoowood The Holme of the Holme Valley, West Yorkshire, England is a tributary of the River Colne, West Yorkshire. The source is via Digley Reservoir, fed firstly by the run-off from Brownhill Reservoir, then by Dobbs Dike. Banks along the upper valley are mostly urbanised and are in the Holme Valley civil parish. The river was prone to flooding, the earliest recorded in 1738. In 1840 the dam of Bilberry Reservoir was built over a stream, but the work had not been done properly and the stream not correctly redirected. Thus in February 1852, the reservoir broke its confines and flooded the valley as far as Holmfirth. It caused 81 deaths and the destruction of many homes and businesses.[3][4] Bilberry Reservoir was constructed in 1840. The top map shows area around Bilberry Reservoir around the time of 1852 flood.
