Loch Oich Reservoir

Stage 1 works to ensure the integrity of the embankments of Loch Oich Reservoir on the Caledonian Canal got underway in 2018/2019 with further flood prevention works planned for 2020.

The Caledonian Canal is one of the Highlands most popular visitor attractions with over 1,400 boats transiting the canal each year.

A canal is normally provided with a water supply by means of reservoirs and feeder channels, however the Caledonian Canal is unusual in that the lochs that are its reservoirs also form part of the waterway itself, with weirs and sluices controlling the water levels.

As part of our statutory obligations as reservoir owners, works are being undertaken to safeguard the integrity of Loch Oich Reservoir and manage risk to the wider public and downstream.  The project which is are set to get underway in 2018 will involve infilling hollows in the downstream slope of the canal embankment, a survey of and localised widening and raising of flood banks, and a review of the flood assessment for this reservoir. The planned studies and repair of flood banks are required to ensure that the earth embankments can withstand extreme floods.

Update April 2020

Flood Risk Assessment stage one has been completed by Aecom, with further flood work to be carried out in 2020. Following this further work, the flood bank crest will be raised to ensure upmost public safety is upheld.

Update October 2018

The removal of the low weir behind Cullochy Bothy and vegetation at the embankment next to Cullochy Lock has been carried out by Scottish Canals staff. A survey of the canal flood banks crest was carried out by Zenith Surveying during the summer, with a Stage 1 Flood Study being awarded to Aecom in October.
