Geography

Loch Morar is 18.8 kilometres (11.7 mi) long, has a surface area of 26.7 km2 (10.3 sq mi), and is the deepest freshwater body in the British Isles with a maximum depth of 310 m (1,017 ft). In 1910, John Murray and Laurence Pullar found it to have a mean depth of 87 metres (284 ft) and a total volume of 2.3073 cubic kilometres (81,482,000,000 ft3) during their survey of Scottish lochs. The bottom is deepened below the United Kingdom Continental Shelf, and until 1943, when a depth of 324 metres (1,063 ft) was observed in the Inner Sound, it was believed to be the deepest water in the United Kingdom. The surface of the loch is 9 metres (30 ft) above sea level.. The lake is the deepest, situated on an island in Europe.

The water of the loch is clear and oligotrophic, with a minimal intake of nutrients, making it a Site of Special Scientific Interest (SSSI). The main inflow is the River Meoble on the southern side, which drains from Loch Beoraid, although there are three other major inflows at the eastern end of the loch and a stream draining a complex of lochans to the north-west of Loch Morar. The outflow is the River Morar at the western end, which at a few hundred metres long is one of the shortest rivers in the British Isles. At the shallower western end of the loch, there are a number of sizeable forested islands.

At the western end of the loch is the village of Morar, which is between Arisaig and Mallaig on the coastal A830 road. The settlements of Bracorina and Bracara are located along the northern shore of the loch, but there is no road along the southern shore. Tarbet, on the shore of Loch Nevis, is a short distance from Loch Morar.
