Below At Wotton Underwood, Buckinghamshire, ‘Capability’ Brown used an enlarged version of a bridge dam to mark the changes in level between two bodies of water. To the visitor crossing the bridge, it looks as if the water flows naturally from one side to the other, whereas the flow from one to the other is controlled by a sluice gate. below right The conduits and sluices that were integral to 18th century dams are prone to silting and are difficult to repair, so many dams of that period have since been modified to incorporate an open spillway, lined with stone. A by pass channel, or leat, could also be used to divert water from the lake to the river on the downstream side of the dam.

Looking at lakes as ornaments in the landscape

For a visitor to a late 18th-century country seat, the most striking feature of the landscape, apart from the house, would have been the lake. For that reason, it is all the more surprising these bodies of water have had such little attention from garden historians and archaeologists. Perhaps that is because it is assumed that they are natural, and that the house site was chosen to overlook the water, whereas the opposite is usually the case, as Chris Catling now reports.
