Thanks Noodles ,Loch more was dammed in 1907. Before this it was one of the most productive spring Atlantic salmon lochs in the world.
However limited space (no#of boats) and the strong winds that are shall we say quite common in Caithness the dam was build to control water flow to make the river more accessible and to hold fish within the main river
The downside to this was raising the level by 12 feet (full loch) from its original level doubled the size and depths of loch More and rendered it a shadow of its former self.
Nowadays only a handful are caught and it fishes best when close to its original level, by which time the fish in it have usually gone stale.
