Tay

The River Tay is Scotland's longest river and the seventh-longest in the United Kingdom. The Tay begins on the slopes of Ben Lui in western Scotland, then flows east through the Highlands, through Loch Dochart, Loch Iubhair, and Loch Tay, then continues east through Strathtay (see Strath), in the center of Scotland, then southeasterly through Perth, where it becomes tidal, to its mouth at the Firth of Tay, south of Dundee. By measured discharge, it is the biggest river in the British Isles. Its catchment area is roughly 2,000 square miles (5,200 km2), whereas the Tweed's catchment area is 1,500 square miles (3,900 km2) and the Spey's catchment area is 1,097 square miles (2,840 km2).
