The Loch Oich wildlife is rich with a wide variety of fish, amphibians, reptiles, birds and mammals.

Thomas Telford artificially raised the level of the loch by many feet to provide a navigable channel for the Caledonian Canal.

[3] The tall needle-like monument on the banks of Loch Oich at the side of the A82 was erected in 1812 by Alexander Ranaldson Macdonell to commemorate the Keppoch murders (Scottish Gaelic: Murt na Ceapaich).

It is topped by a sculpture of a hand holding a dagger and seven severed heads.

The monument bears an inscription in Gaelic, English, French and Latin that outlines "the ample and summary vengence which, upon the orders of the Lord MacDonnell and Aross, overtook the perpetrators of the foul murder of the Keppoch family, a branch of the powerful and illustrious clan of which his lordship was the Chief".
