caused by flow into the Loch. Thus, unlike most situations where slack water is at high and low tides, in the case of the Falls of Lora slack water occurs when the levels on either side are the same, not when the tidal change is at its least. As a result, the tidal range is much greater on the coast than it is inside the loch. A range at
