River Tummel. The River Tummel is a river in Perth and Kinross, Scotland.
Water from the Tummel is used in the Tummel hydro-electric power scheme, operated by SSE. As a tributary of the River Tay the 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. Discharging from Loch Rannoch, it flows east to a point near the Falls of Tummel, where it bends to the southeast, a direction which it maintains until it falls into the River Tay, just below Logierait, after a course of 58 miles from its source in Stob Ghabbar.
Its only considerable affluent is the Garry, 24 miles long, an impetuous river which issues from Loch Garry. About midway in its course the Tummel expands into Loch Tummel, between which and the confluence with the Garry occur the Pass and Falls of the Tummel, which are rather in the nature of rapids, the descent altogether amounting to 15 ft. Loch Tummel was previously 4.43 km long and 39 m deep, but with the construction of the Clunie Dam in 1950, the water level was raised by 4.5 metres, and Loch Tummel is now approximately 11 km long.
The scenery throughout this reach is most picturesque, culminating at the point above the eastern extremity of the loch, known as the Queen's View. The chief places of interest on the river are Kinloch Rannoch;
