Loch Lubnaig, Callander, Scotland.

Loch Lubnaig (Loch Lùbnaig in Gaelic) is a small freshwater loch near Callander in the Stirling council area, Scottish Highlands. It lies in the former county of Perthshire. Loch Lubnaig differs from the other lochs in the neighbourhood in that it does not contiture a single basin. The bottom is apparently very irregular; the contour lines of depth do not follow the contour of the loch. Hollows and ridges alternate with each other and in some placed comparatively deep water is found close to the shore, while in other places shallow water extends a considerable distance from shore. The loch is also comparatively speaking, very narrow and shall considering its size, nearly two-thirds of the area being under 50 feet in depth. The loch may be conveniently divided into two halves, defined by the central constriction in the outline of the loch at the entrance of the Ardchillarie burn, where the bottom shallows and separates two principal deep depressions. The northern half trends in a north-west and south-east direction, while the southern half trends almost directly north and south. There are two depressions in which the depth exceeds 100 feet, with an isolated sounding of 106 feet between them. The larger depression is contained in the southern half of the loch and is over half a mile in length with a maximum width of about 280 yards wide. The smaller but deeper depression is situated at the base of the northern half of the loch, occupying a central position and is over 0.25 miles in length with a width of 280 yards. The deepest part of the loch at 146 feet is centrally located in the depression. There are three other smaller depressions. On the western shore, between 1.25 and 1.5 miles from the southern end of the loch, there is a sandy spit, which stretches out towards the centre of the loch.
