THE FRESH-WATER LOCHS OF SCOTLAND. 
245 
of 416 and 419 feet, separated by an interval of three-quarters of a 
mile (in which the greatest depth is 375 feet) from the larger, which 
is less than a mile in length and encloses the maximum depth of the 
loch (420 feet), recorded near the north-eastern end of this larger basin, 
and over 4 miles from the head of the loch. The line of soundings, 
which includes the deepest one, is shown on cross-section G-H on map 
(Plate LIII.).

From the foregoing description, it will be noticed that in Loch Shiel 
the deeper water occurs towards the head of the loch. Proceeding from 
• Acharacle, at the foot of the loch, one must row 2 miles up before 
encountering a depth of 50 feet ; a further 1 J miles before meeting with 
a depth of 100 feet, and this merely a small patch, a further IJ miles 
having to be traversed before reaching the main 100-feet basin, or a 
total distance of 5 miles from the foot of the loch. The main 200-feet 
basin is distant about 9 miles, the lower 300-feet basin nearly 10 miles, 
and the principal 400-feet basin over 12 miles, from the foot of the 
loch.
