The Tummel is the most heavily regulated river on the Tay system — a Highland tributary that runs out of Loch Rannoch through Loch Tummel and finally through the great dam at Pitlochry, where the famous fish ladder lets salmon up to the upper lochs and where anyone passing through in the summer stops to watch them through the glass. Below the dam the river fishes very well for salmon in the summer and autumn months, with the Pitlochry beats offering some of the more accessible salmon fishing in central Scotland — not cheap, but available to day-ticket anglers in a way the Dee and Spey largely aren't. The river also holds good brown trout throughout, and a small but genuine grayling population that fishes well in winter. A hydro river, undeniably, but a proper fishing river too.
