River Tay
The River Tay emerges from Loch Tay at Kenmore, and flows from there to Perth which, in historical times, was its lowest bridging point. Below Perth the river becomes tidal and enters the Firth of Tay. The largest city on the river, Dundee, lies on the north bank of the Firth. On reaching the North Sea, the River Tay has flowed from west to east across central Scotland.
River Dochart
Coming from Ben Lui, it flows east out of Loch Dochart and through the glen of the same name. At Killin just before it enters Loch Tay are the Falls of Dochart. The river is sometimes also considered to be a part of the upper reaches of the River Tay.
