The Overtoun Burn follows an artificially straight channel through this area. This new channel was built at the same time as the adjacent ornamental lily pond (
NS4276 : Former dam and lily pond), which doubled as a source of water for a domestic hydro-electric power scheme, providing electricity for
NS4276 : Overtoun House. See
NS4276 : Remains of a turbine house for the details of that scheme.
Close inspection of large-scale mapping shows the lily pond to be separate from this channel. Water was transferred from one to the other by means of a sluice gate:

NS4276 : The channel of the Overtoun Burn. See also

Further downstream, just beyond the southern end of the lily pond, the artificial channel of the Overtoun Burn shows signs of more recent work (1970s), with gabions (rocks contained in a wire mesh). The first-edition OS map (c.1860) pre-dates the hydro-electric scheme, and shows the original course of the Overtoun Burn, before the pond/dam was created.
Overtoun House hydro-electric scheme This was one of the earliest examples of a hydro-electric scheme producing power for domestic use: in around 1892, the occupant of Overtoun House, John Campbell White (soon to be created Lord Overtoun), had a turbine house built to provide electricity for his home. See Link for more on Overtoun House. The ruins of the turbine house are located beside a waterfall called Spardie Linn – Link – on the course of the Overtoun Burn. Water was impounded further up the burn in a dam, which doubled as an ornamental lily pond. The dam is fed by the Overtoun Burn, whose channel, just upstream of the pond, can be seen to have been artificially straightened; the remains of a sluice gate are visible there.
