THE FRESH -WATER LOCHS OF SCOTLAND.

greater (over 35 J square miles). The maximum depth of 282 feet was 
observed about 1^ miles from the east end, and about 5J miles from the 
west end. The volume of water is estimated at 10,920 millions of cubic 
feet, and the mean depth at nearly 109 feet. Loch Fannich forms a 
simple basin, all the contour-lines enclosing continuous areas, though 
the deepest part (exceeding 200 feet in depth) lies in the eastern 
half of the loch. The 50-feet area extends from end to end, coinciding 
approximately with the outline of the loch. The 100-feet area 
approaches to within half a mile from both ends, and is nearly 6 miles 
in length ; there is a slight shoaling of the water opposite Rudha Mbr

to 103 feet, with deeper water to the east and west. The 150-feet area 
is distant over 2J miles from the west end, and is over 3J miles in 
length. The 200-feet area is 2J miles, and the 250-feet area IJ miles, 
in length, and they approach to within three-quarters of a mile from 
the east end. The slight shoaling opposite Hudha Mor has already been 
referred to, and a similar shoaling is observable within the 200-feet 
contour opposite Fannich Lodge, where the depth decreases from 226 
feet to 212 feet, and increases again on proceeding eastwards into the 
250-feet area ; these two shoalings are indicated in the longitudinal 
section A-B on the map. A sinuosity is also seen in the 200-feet contour 
off the southern shore, opposite Fannich Lodge, due to the shoaling of 
the water from 202 to 191 feet, but on the whole the lake-floor may 
be said to be extremely regular in conformation. The cross section
