Quick Summary

The Pitlochry Dam in Scotland is a component of the Tummel-Garry Hydro-Electric Scheme. This scheme utilizes the River Tummel, which flows through Loch Laidon, Loch Rannoch, and Loch Tummel before joining the River Tay near Pitlochry.1

The dam incorporates drum gates, a type of auxiliary structure used in modern dams. These gates can automatically control reservoir water levels without external power. One design involves a caisson held by hinges, with water pressure and buoyancy maintaining equilibrium. Adjusting the water level in a flotation chamber rotates the caisson, regulating water flow. Pitlochry Dam features two such drum gates.2
