Not to be confused with the minor dam carrying the track along the N side of the reservoir across a burn, for which see NT26SW 63.04.
The earthern dam ('bank') measures up to 77ft (23.5m) in height and 86,335 cu yds (66,005 cu m) in volume. Situated at a point where the stream channel was narrowed by a projecting rocky spur, its construction gave considerable difficulties. In excavating the foundation, it was discovered that the gravel bed was no less than 53ft (16.2m) deep; when this was removed to make the required clay-puddle dyke, the hill on the S side (comprising loose and friable felspathic trap) collapsed.
J Colston 1890.
