The Highland Council has said that the ground above the road the connects Loch Garry with Kinloch Hourn is ‘very high risk’.
The 1km slope failure near Invergarry on 10 November knocked out the power supply to the Isle of Skye and the Western Isles, deposited 9,000t of material into the dam spillway, forcing power station operations to be stopped.
Now the Highland Council has reported that Mott MacDonald geotechnical engineers have categorised the area of the slip as very high risk which prevents any attempt to clear debris from the road under the large loose material on the slope above. This material must be stabilised first.
SSE Transmission have re-instated their cables and have now handed over control of the road site to the council.
A slope stabilisation and road clearance plan is being developed as a matter of urgency by the stakeholders reported the council, and its senior engineer Amanda Henderson will be visiting the site today (Wednesday 5 December).

Arrangements are in place and a temporary All Terrain Vehicle(ATV) access route has been established with the help of SSE Generation and landowners.
A road block to prevent members of the public entering the high risk area, and to direct essential users to the ATV diversion is now in place and is manned during daylight hours. Non-essential users are asked to avoid the area altogether.
The route is likely to remain closed until mid-2019.
