River Lochay
The River Lochay in Perthshire is a highland river and one of the two sizable rivers which combine to create the River Tay, the other being the River Dochart.
The Lochay rises in the Mamlorn Hills in western Perthshire, its streams from the flanks of Beinn Challuim uniting in the Breadalbane district to create the River Lochay, which flows eastwards, with the Forest of Mamlorn to its north. Soon the river begins to carve its distinctive valley, Glen Lochay.
Swelling with each burn it swallows, the Lochay finally turns southeast and tumbles over the pretty Falls of Lochay and two and a half miles below this it enters the village of Killin, and meets the River Dochart: the two unite immediately before that pour into Loch Tay.
The river emerging from Loch Tay is the River Tay itself.
