Concerns have been raised over water levels on Loch Ness and the River Ness.

The loch dropped to its lowest level in 32 years last month amid dry conditions, according to Scottish Environment Protection Agency figures.

Ness fishery board said levels remained concerningly low and claimed water that could help ease the situation was being stored – unused – for hydro-power.

Energy company SSE Renewables said it was managing its water use sensitively amid challenging weather conditions.

Loch Ness is Scotland’s largest freshwater loch by volume, while the River Ness flows from Loch Dochfour, at top of Loch Ness, and out to sea at Inverness. The loch and river are part of what is called the Ness system, an area of burns, rivers and lochs that extends south-west of Inverness.
