According to Webster, Lochend or *Luscar-Wingate included Bonnyton CNK and part of Rosebank CNK (1938, 310 ff). It also included Drumtuthill DFL. See Luscar for more discussion. The loch of the name was probably the predecessor of the Craigluscar Reservoirs. See also Lochend DFL, almost certainly a different place.
