Loch Oich is a freshwater loch in the Highlands of Scotland which forms part of the Caledonian Canal, of which it is the highest point.
This narrow loch lies between Loch Ness (to the north-east) and Loch Lochy (to the south-west) in the Great Glen.
It is fed by the River Garry (from Loch Garry) from the west, and feeds the River Oich from its northern end.
The Laggan locks separate it from Loch Lochy.
The Loch Oich wildlife is rich with a wide variety of fish, amphibians, reptiles, birds and mammals.
Every autumn the Atlantic salmon (Salmo salar) migrates from the sea using Loch Oich, Loch Lochy and Loch Ness as their spawning nests.
