This cache takes you to the Backwater Reservoir in Glen Isla.
This reservoir was created in the 1960s to supply the water needs
of Angus and Eastern Perthshire. When it was constructed it was one
of the largest earth embankment reservoirs in Europe. It is
certainly an impressive sight as you drive up towards it. The
reservoir is also unique in that it was the first British reservoir
to be constructed using a method of chemical grout injected into
the glacial bedrock, in order to prevent leakage under the
dam.
For the statisticians amongst you, the dam is
43metres high, and approx 500metres long. The reservoir
length is 3.2 Km and it can hold 25million cubic metres of
water. The maximum daily demand on the water supply is around
100,000cubic metres, so by doing the maths the reservoir can
last for a "dry spell" of 250 days.
Parking for the cache is at the picnic area /
toilets at N56 42.980 W003 13.517. The route to the
cache is along a tarmac roadway suitable for
wheelchairs/pushchairs until the last 50 yards or
so.
The container is an ammo box containing all the
usual goodies. Please replace it as close as you can to its
original location to prevent it standing in pools of
water.
Please note: Due to the terrain you may find
deviations in the GPSr readings. A good indication of the
direction to cache can be found while moving along the tarmac
road.
