The course of a rail-bed, following the S side of the pipeline from the Blackwater Dam (NN26SW 3.00) was observed during a pre-afforestation survey by AOC (Scotland Ltd). The tracks are set into concrete and are 0.5m apart. A pylon beside the track suggests that there was originally an overhead cable. The pylon stands 6.5m in height and consists of two uprights which are 3m apart and a cross bar carrying winch gear. There is a 5m long brace extending from the pylon into the hillside above the rail line. It is situated immediately W of the buildings where the open conduit changes into a pipeline.

The location assigned to this record is arbitrary. The available (GIS) map evidence depicts this structure as extending from NN 24731 60260 to NN 20214 60445, along the S side of the upper valley of the River Leven.

This aqueduct carried water for power generation at the Kinlochleven Aluminium Works (NN16SE 3.00) from the Blackwater Dam (NN26SW 3.00) to the lower penstock house (NN26SW 3.03), where it entered the pipeline NN16SE 1. Numerous small aqueducts and sluices control the relationship of the aqueduct with streams flowing downhill (from the S). These await detailed recording.

Activities

Field Visit (2010)

This closed concrete aqueduct carries water from the Blackwater Dam outlet downhill to the penstock inlets. It is a closed U section waterway made from concrete. It is predominantly on or just under the ground, although in some sections it is bourn on an arcade of concrete arches across small streams. This is a significant linear feature with some subterranean sections. It is functionally linked to the scheme. The arched sections which convey the aqueduct across uneven sections of ground are of technical interest as early examples of the use of reinforced concrete.
