Loch Ericht

Loch Ericht (Scottish Gaelic: Loch Eireachd) is a freshwater loch on the border between the former Perthshire, now Perth and Kinross and the former Inverness-shire, now Highlands Council areas of Scotland. It has a north-east to south-west orientation. The village of Dalwhinnie lies at the north east end of the loch. Loch Ericht is the tenth largest freshwater lake in Scotland and has a good reputation for its trout fishing and Ferox trout. Loch Ericht occupies a major glacial breach cut through the former main Grampian divide from Ben Nevis over Ben Alder to the Cairngorms. The breach exploits the Loch Ericht Fault, a major feature of the Caledonian Orogeny, parallel to the Great Glen Fault and other NE-SW faults. The preglacial col in the former divide at Beinn Bheoil - Stob an Aonaich Mhoir is estimated by Linton to have been at 650m asl. With the loch bed being at 200m asl, ice has excavated a trench at least 450 m deep. The glacier has carried erratic boulders of Rannoch granite far down the flanks of Strath Spey. A secondary breach was cut between The Fara (Am Faireamh) and Geal Charn (Drumochter) thus beheading the Pattack catchment. The present watershed has been displaced about ten miles north-east to Dalwhinnie. The loch is part of a hydro-electric scheme and is dammed at both ends. Water flows into the northern end via the Cuaich Aqueduct. The southern end is linke
