150 years of dams

image depicting Wimbleball under construction
Wimbleball under construction
Our oldest dam is the 1861 construction at Tottiford, Devon, and 20 further dams were build across the region in the next 150 years.

Many communities began with small river valley dams but as the management of water became more regional, the authorities needed larger constructions and more water resources.

Many of these reservoirs represented major civil engineering projects in often remote locations, such as the stunning multiple buttresses at Wimbleball on Exmoor.
