The River Tay is the longest river in Scotland and the seventh-longest in Great Britain. The Tay originates in western Scotland on the slopes of Ben Lui, then flows easterly across the Highlands, through Loch Dochart, Loch Iubhair and Loch Tay, then continues east through Strathtay, in the centre of Scotland, then southeasterly through Perth, where it becomes tidal, to its mouth at the Firth of Tay, south of Dundee. It is the largest river in the United Kingdom by measured discharge. Its catchment is approximately 2,000 square miles, the Tweed's is 1,500 sq mi (3,900 km2) and the Spey's is 1,097 sq mi (2,840 km2).
Loch Rannoch is a freshwater loch in Perth and Kinross, Scotland. It is over 15 kilometres (9.3 mi) long in a west–east direction with an average width of about 1.2 kilometres (0.75 mi), and is deepest at its eastern end, reaching a depth of 130 metres (440 ft). The River Tummel begins at its eastern end, where the small village of Kinloch Rannoch can be found, whilst the wild expanse of Rannoch Moor extends to the west of the loch. The area surrounding Loch Rannoch, along with Rannoch Moor itself, was formerly part of the native Caledonian Forest that stretched across much of Northern Scotland. Native forest is now largely absent from much of the area, due partly to logging, and partly to the climate becoming wetter, and Loch Rannoch is now largely surrounded by commercial forestry and open hillsides, although a small area remains at the Black Wood of Rannoch on the southern shore of the loch.
Rannoch is an area of the Scottish Highlands between the A9 road, to the east, and the A82, to the west. The area is crossed from south to north by the West Highland railway line.

The Tummel hydro-electric power scheme is an interconnected network of dams, power stations, aqueducts and electric power transmission in the Grampian Mountains of Scotland. Roughly bounded by Dalwhinnie in the north, Rannoch Moor in the west and Pitlochry in the east it comprises a water catchment area of around 1,800 square kilometres and primary water storage at Loch Ericht, Loch Errochty, Loch Rannoch and Loch Tummel, in Perth and Kinross. Water, depending on where it originates and the path it takes, may pass through as many as five of the schemes nine power stations as it progresses from north-west to south-east. The scheme was constructed in the 1940s and 50s incorporating some earlier sites. It is managed by SSE plc.
Loch Errochty is a man made freshwater loch situated within the Perth and Kinross council area at the edge of the Scottish Highlands near the Highland Boundary Fault where the topography changes to lowland.

The River Garry in Inverness-shire is a Scottish river punctuated by two long Lochs, in the region of Lochaber. It flows broadly west to east through Glen Garry, starting in a wilderness to the east of Knoydart and ending at Loch Oich in the Great Glen, which forms part of the Caledonian Canal. There are a few tiny settlements within Glen Garry, but the only village of any size near to the river is Invergarry, at its mouth. Loch Quoich at the western end of the watercourse is dammed by the largest mass earth fill dam in Scotland, and supplies water to Quoich hydroelectric power station. Loch Garry is dammed by a much smaller dam in the gorge where the river begins its descent to Invergarry, and supplies water to Invergarry hydroelectric power station, close to the mouth of the river. Both hydroelectric schemes were built in the 1950s, with the aim of stimulating economic regeneration in the area. They have altered the ecology of the river, as both lochs were made considerably bigger as a result of constructing the dams.

The Loch Rannoch and Glen Lyon National Scenic Area is a national scenic area (NSA) covering the area surrounding Loch Rannoch, Glen Lyon, and the Ben Lawers ranges of mountains in Scotland. It is one of 40 such areas in Scotland, which are defined so as to identify areas of exceptional scenery and to ensure its protection from inappropriate development by restricting certain forms of development. The Loch Rannoch and Glen Lyon NSA covers 48,625 ha, most of which lies in the council area of Perth and Kinross, with a small portion lying in Stirling.
