Asgog Loch is a natural freshwater loch in Argyll and Bute, Scotland. It is located about 4 kilometres (2.5 mi) southwest of Tighnabruaich, on the Cowal peninsula. The loch was dammed during the 19th century to create an impounding reservoir for the supply of freshwater to the Low Mills of the nearby gunpowder mills at Millhouse (the Kames Powder Works).[2]
The remains of three crannogs, or artificial islands, have been observed within the loch on occasions when the water level has been lowered.[3][4] Asgog Castle stands on the northwest shore of the loch.
