Howden Dam Howden Reservoir

Howden Dam at Howden Reservoir is a dam constructed between 1901 and 1912, designed by engineer Edward Sandeman with architectural advice from W. Flockhart. It is built from coursed, squared rock-faced gritstone, with a core made of large stone blocks set in concrete. The dam stands 117 feet high and is 178 feet thick at the base, tapering to 10 feet at the top.

The structure features two castellated towers with arched corbel tables and pairs of small round-arched windows on three sides, while a door is located on the fourth side. Massive gateways at each end have battered sides and banded rock-faced rustication. The entrance arches are of a pseudo Gibbs-type, adorned with large vermiculated blocks and a solid pediment. Parapet walls connect the gate piers to the towers, featuring a dentil course on the south side.

At the base of the western tower, there is a foundation stone inscribed with a dedication to the construction of the reservoir, which was built by the Derwent Valley Water Board for the benefit of the people of Derby, Leicester, Nottingham, Sheffield, and Derbyshire. The western part of the dam is located in the parish of Hope Woodlands, Derbyshire.
