Loch Ericht, lake in Perth and Kinross, and Highland, Scotland, UK, outflows to River Ericht
Loch Ericht is a large lake in the Scottish Highlands that stretches for more than 14 miles (22 kilometers) through a mountain valley, with a width of less than 1 mile (1.6 kilometers). The lake runs from northeast to southwest and is controlled by dams at both ends as part of a hydroelectric power system.
The lake was formed during the ice age when glaciers carved out a deep valley that later filled with water. In 1931, it was converted into a reservoir with dams built to generate hydroelectric power for the region.
The name Loch Ericht comes from Gaelic roots and reflects the historical importance of this area to local communities. Today, visitors can experience how the lake connects small villages like Dalwhinnie to the surrounding mountains, with the water playing a central role in the daily life and character of the region.
The shoreline is mostly accessible only on foot, as most of the banks are undeveloped and small boats may be needed to reach certain areas. Mountain weather can change quickly, so visitors should bring warm clothing and waterproof gear and be prepared to adjust their plans.
Water from the lake is channeled through an aqueduct called Cuaich at the northern end to power stations at Loch Rannoch, where it generates electricity. This hidden system connects multiple lochs and shows how hydroelectric power has shaped the Scottish Highlands for nearly a century.
