THE FRESH- WATER LOCHS OF SCOTLAND.

Loch Turret (see Plate XXXII.). — ^Loch Turret, in Glen Turret, 
near Crieff, is used as the source of the water supply to the town of 
Crieff. It is a good trout loch, but strictly preserved, and is situated 
amid wild and beautiful scenery, the hills being steep and high on both 
sides, especially to the west, where crags border the loch. It flows by 
the Turret burn into the river Earn, and it receives the waters from 
the little Lochan Uaine, lying at the head of the glen, which was 
surveyed on the same day by request of the proprietor. Loch Turret 
trends in a north-west and south-east direction, and is widest towards 
the southern end, narrowing somewhat towards the northern end. It 
is over a mile in length, and over one-third of a mile in maximum 
breadth, the mean breadth being a quarter of a mile, or 24 per cent, of

the length. Its waters cover an area of about 164 acres, or a quarter 
of a square mile, and it drains an area 23 times greater — an area of 
nearly 6 square miles. Seventy soundings were taken, the maximum 
depth observed being 79 feet. The volume of water contained in the 
loch is estimated at 227,718,000 cubic feet, and the mean depth at 
32 feet, or 40 per cent, of the maximum depth. The length of the 
loch is 70 times the maximum depth and 173 times the mean depth. 
Loch Turret forms on the whole a simple basin, the deeper water 
approaching nearer to the northern end and the western shore. The 
wide southern portion is comparatively shallow (under 20 feet), with 
one or two slight irregularities of the bottom, as, for instance, near the 
south-western angle of the loch, where soundings of 8 feet and 9 feet
