Loch Màma

Loch Màma is a small freshwater loch in South Morar, Lochaber, in the north west of Scotland. It forms a simple basin and is orientated east to west. It is thought that the adjoining loch Loch na Creige Duibhe and Loch Màma were at one time a single loch. Debris brought down by the Allt Dearg stream has likely caused the lochs to be separated into two bodies of water. The loch is the source of the river Allt a' Mhama.^[1]
