Loch a' Bhaid-luachraich (Loch of the Clump of Rushes) is a large shallow freshwater loch located directly south of Aultbea in Wester Ross. Loch a' Bhaid-luachraich can almost be considered as two irregular shaped lochs connected by a narrow channel. The south-west portion of the loch is the shallowest with the maximum depth of around 38 feet while the north-east section is the deepest at 141 feet. Loch a' Bhaid-luachraich drains into the Allt Beithe in the north which empties into the Loch Ewe sea loch at the small village of Aultbea about 1 mile north-west. Loch Mhic' Ille Riabhaich (Loch of the Son of the Brindled Lad), located to the south-east, drains into the loch from the south along the Uidh Mhic 'Ille Riabhaich stream.
Loch a' Bhaid-luachraich is surrounded by low peatland covered round hillocks except the small hill of CÃÂ rn bad na h-Achlaise (The Cairn at the Bend of the Armpit) that is situated directly to the southeast at 243 metres.
Arctic char was discovered in Loch a' Bhaid-luachraich in 2012. This is the first time a population of such fish has been discovered there since before 1940.
