Laggan-Treig Tunnel [Adit] (Loch Treig)

Loch Treig, Lochaber, Inverness-shire.

Tunnel, Hydro-electric scheme.

Concrete lined tunnel, below level of railway line along NE side of Loch Treig. Part of the Laggan-Treig Tunnel complex?

"This tunnel is located on the North shore of Loch Trieg, just below the West Highland railway line, around 1-2km from the dam - ref. NN348767. Correspondant also reports a loud noise 'as if from turbines' coming from further down the tunnel. There ARE no turbines in this tunnel, I know this for a fact. Perhaps simply the noise of water flowing in the main tunnel from Laggan to Treig? - this MUST be an adit to that tunnel.

2/2/04 update... the adit is a *very* long way from the outlet of the Laggan tunnel - too far to be an adit to that tunnel, I suspect.. it slopes down at a constant ~20-25%, lined for around 30 feet, then opening into a larger unlined section for another 30 feet, from that point on it is flooded."

Given coordinates are general, based on 6 fig NGR. This is c.400m from the Laggan-Treig Tunnel's outfall point. The conspicuous semi-spherical bank along the shore at this point may be spoil waste removed from the adit.
