Loch Tummel

Loch Tummel (Scottish Gaelic: Loch Teimheil) is a long, narrow loch, seven kilometres (4+1⁄2 miles) northwest of Pitlochry in the council area of Perth and Kinross, Scotland. It is fed and drained by the River Tummel, which flows into the River Tay about 13 km (8 mi) south-east of the Clunie Dam at the loch's eastern end.

The loch is traversed by roads to both north and south. Along the northern side the road is numbered as the B8019, and runs from the Pass of Killiecrankie on the A9 in the east to Tummel Bridge at the head of the loch. The road on the southern side is unclassified, and meets the A9 further south, near to Pitlochry.

The loch gives its name to the Loch Tummel National Scenic Area (NSA), one of 40 such areas in Scotland, which are defined so as to identify areas of exceptional scenery and to ensure its protection by restricting certain forms of development. The Loch Tummel Lyon NSA covers 9,013 hectares (22,272 acres), all of which lies within Perth and Kinross. The NSA covers the hills surrounding the loch, and extends along the River Tummel to also take in the area surrounding the Pass of Killiecrankie on the River Garry.

Loch Tummel is popular with anglers who fish for brown trout and pike. Fishing is managed by the Loch Rannoch Conservation Association, who issue permits and control catches. Loch Tummel Sailing Club is based at Foss on the south west shore of the loch. The loch is also very popular with campers during the spring and summer. The roads on either side of the loch both offer splendid views of the surrounding countryside, especially from the well-known 'Queen's View' from the north shore, which was made famous by Queen Victoria in 1866. This viewpoint offers a magnificent vista over the loch with Schiehallion in the background. It is also claimed that the view was originally named after Queen Isabel, wife of Robert the Bruce, who is said to have hidden in the nearby woods after the Bruce's defeat at the Battle of Methven in 1306.

Areas of forestry around Loch Tummel owned by Forestry and Land Scotland (FLS) form part of the Tay Forest Park, a network of FLS forests spread across the Highland parts of Perthshire that are managed to provide walks and amenities for visitors.

The River Tummel is a tributary of the River Tay, and Loch Tummel is included as part of the River Tay Special Area of Conservation. The designation notes the river system's importance for salmon, otters, brook lampreys, river lampreys and sea lampreys. Brown trout and pike are also present in the loch.

The woods to the north of the loch are home to a number of protected species, including capercaillie, black grouse, red squirrel, pearl-bordered fritillary and juniper.

Loch Tummel became part of the Tummel Hydro-Electric Power Scheme when the Clunie Dam was constructed by Wimpey Construction at its eastern end in 1950, raising the water level by 4.5 m (15 ft). Prior to this the loch, which is now approximately 11 km (7 mi) long and just under 0 km (1 mi) wide was much smaller, being 4.4 km (2+3⁄4 mi) long and 0.8 km (1⁄2 mi) wide.
