Talla Reservoir
Top water level 290 metres above Newlyn datum [NAT]
(name centred NT 117 215)
OS 1:10,000 map, 1989.
Developed under the name of the New Water Supply by the Edinburgh and District Water Trust, the Talla Scheme was adopted on 11 October 1894. It comprised a storage reservoir, a service reservoir and filter, main and branch aqueducts, and a railway from Broughton Station to Talla. The authorising Act received the Royal Assent on 30 May 1895.
The length of the loch at maximum is about 2.5 miles (12.1km), and the greatest depth of water (close to the dam) about 80ft (24.4m). The total capacity is about 2,800 million gallons (12,727,000,000 lit).
W A Tait 1905.
This reservoir was formed by damming the Talla Water, a tributary of the Tweed, and lies entirely within the parish of Tweedsmuir. It forms a major element of the water supply for Edinburgh, being built as a major element of the early 20th century development of the system.
