 Lochend Loch was a post-glacial 'Kettle Hole' lying within a substantial depression and fed by the relatively minor flow of the Joppa Burn, field runoff and rainfall, its outflow running into the Water of Coyle as the Barwhey or Barquey Burn.A small islet is indicated on the early OS maps, no longer shown when the loch level was lowered in the late 1890s or early 1900s.Roy's map of 1747 shows the then sizeable loch with a roughly circular island near the centre of the loch; the outflow joined the Water of Coyle near Coyle bridge.
