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 metres (1,037 ft) long. The reservoir has a catchment area of 23 square kilometres (8.9 sq mi), and is capable of holding seven Gigawatt hours of energy. The water level in the reservoir can fluctuate by as much as 10 metres (33 ft) a day due to the operation of the power station.
This geocache can easily be incorporated into a day walking the circular walk around the summits and munros that surround the reservoir. However, it can be completed as a standalone hide. You can park at the given coordinates and enjoy a climb up the valley on the rough path to the reservoir. The is a very scenic track up one side of the reservoir for those who don't wish to climb the hills, and you can walk over the dam. There isn't a proper path all the way around the reservoir. From this hide, you can enjoy spectacular views of Loch Awe and of the reservoir. Please re-hide it carefully so it isn't muggled and is safe from the elements as the wind and weather can be strong up here.
