Dunalastair Water ( Scottish Gaelic : Loch Dhùn Alastair ) is a reservoir in the Scottish Highlands . It is located approximately 23 km west of Pitlochry between Loch Rannoch and Loch Tummel in the Council Area Perth and Kinross . The north bank of the lake is accessed by the well-developed B846, while the south bank can only be reached via a single-lane side road with passing points.
The reservoir was created in 1933 when the River Tummel was dammed. The lake is part of the Tummel hydro-electric power scheme and is used to generate electricity from hydropower. Dunalastair Water is about 2.5 km long and up to 800 m wide. The water surface covers approximately 1.65 km². The dam at the eastern end of the lake is 65 m wide. Immediately behind the dam, Dunalastair Water has more of the shape of a meandering river, only in the rear, further west, does the lake expand into a larger open water area.
Dunalastair Water is extremely shallow. The average depth is only 1.5 m, which results in exceptional biological conditions. The water in the lake heats up much faster than is the case in other Scottish lochs, some of which are well over 100 m deep. Above all, many wild birds, such as warblers , bitterns , gray herons , great egrets and winter golden cockerels have settled at the lake. Dunalastair Water has therefore been declared a Site of Special Scientific Interest . In addition, the lake is a particularly attractive fishing area where brown trout are primarily caught.
