Ladybower Reservoir as viewed from Bamford Edge.
The reservoir is Y shaped and is the lowest of three in the Derwent Valley. The higher reservoirs are Howden and Derwent.
This image gives a good view of the water in the sunlight. You can also make out the Ladybower Viaduct and the dam wall to the left.
Please note that Peter adds new photographs to his online collection at regular intervals. In a bid to make sure that he remains in the real world he limits his time online!
