Backwater Reservoir - Angus

Backwater Reservoir in the northwest, the reservoir's sole purpose is to provide drinking water, and as such, it supplies Angus, Dundee, and parts of Perth and Kinross.

Backwater, together with the smaller Lintrathen Reservoir 4 kilometres to the south, is capable of supplying some 300,000 people with drinking water.

Backwater Reservoir is located within Glen Isla. The reservoir can be reached by taking the B951 turn-off from the A93 (around 5 miles south of Spittal of Glenshee) to the north-west, or from the A926 at Kirriemuir to the south-east. The perimeter of the reservoir forms a popular walking route.

The reservoir extends for 3 kilometres behind the dam and has a peak capacity of 24.55 million cubic metres (867×10⁶ cu ft).^[1] An unclassified road runs across the spillway and embankment before following the east bank of the reservoir. This road runs for a further 2 kilometres before coming to an end. The dam was the first in Britain to use chemical grouting to create a waterproof barrier below the
