Cruachan Reservoir

Cruachan Reservoir is a reservoir in Scotland. It is located to the north west of Loch Awe, in a corrie beneath Ben Cruachan. It is the upper reservoir for the Cruachan Power Station pumped-storage scheme.

It was created in the 1960s, and is contained by a dam 316 m long.

The reservoir has a catchment area of 23 km2, and is capable of holding seven Gigawatt hours of energy. The water level in the reservoir can fluctuate by as much as 10 m a day due to the operation of the power station.
