Derwent Dam

Derwent Dam is a dam constructed between 1902 and 1916, designed by engineer Edward Sandeman with architectural advice from W. Flockhart. It is made of coursed squared rock-faced gritstone, with a core of large stone blocks set in concrete. The dam measures 1,110 feet long and stands 114 feet high, with a base thickness of 178 feet that tapers to 10 feet at the top. It features two castellated towers with arched corbel tables, small round-arched windows on three sides, and a door on the fourth side. There are massive gateways at each end, which 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 and include a dentil cornice on the south side.
