THE FRESH-WATER LOCHS OF SCOTLAND. 
401 
water on October 3, 1903, was 364-9 feet above the sea; on June 22, 
1867, the Ordnance Survey officers found it about 6 feet higher (371-5 
feet) . 
In form Loch Meiklie is approximately oblong. A shallow inlet, 
formed by the encroachment of the river, runs one-sixth of a mile from 
the west end. The basin is quite simple, with the slopes everywhere 
gentle, but steepest towards the north shore at the deepest part. Over 
one-half of the whole area is less than 20 feet in depth. The volume of 
water is 193 millions of cubic feet, making Loch Meiklie the ninth in 
point of bulk in the Ness basin. 
The surface temperature on October 3, 1903, was 53°-6 Fahr. 
Loch Aslaich (see Plate Cl.). — An extremely beautiful little loch, 
about 5 miles west of Loch Ness, surrounded by hills of considerable 
height, rising to about 2000 feet in the immediate neighbourhood of the 
loch. On a picturesque wooded island in the loch the members of the 
Lake Survey had their abode (in a lodge kindly lent by the proprietor), 
while the lochs of the district were being examined. In form the loch 
is a narrow oblong, with its long axis running north and south. It is 
one-third of a mile long, with a maximum breadth of one-seventh of 
a mile. Its superficial area is about 21 acres (only Lochs Dubh and 
nan Losganan being smaller), and it drains an area of nearly 2 square 
miles. This area includes a larger loch (Loch nam Meur), which was 
not surveyed. Besides the chief feeder, the burn coming from Loch 
nam Meur, two small burns enter the loch. The river Coiltie has its 
origin in Loch Aslaich, and flows into the Enrick just where it enters 
Loch Ness. Its volume is 10 millions of cubic feet; in this respect 
Lochs Lundie (by Clunie), Laide, Dubh, and nan Losganan, are 
smaller. The height of the loch above the sea was estimated at 1310 
feet. Fully half the superficial area is covered by less than 10 feet of 
water. The area of more than 20 feet in depth forms a narrow strip 
along the west side. This comes very near to the south end, and the 
deepest sounding, 26 feet, is quite close inshore. The mean depth is 
11 feet. 
On July 2, 1904, the temperature at the surface and at 6 feet was 
60°‘0 Fahr., and at 18 feet, 56°-3. 
Loch Duhh (see Plate XCI.). — A very little lochan a couple of miles 
to the west of Loch Ness and 4 miles south of Glen Urquhart. The 
shortest loch in the basin, but in all other dimensions the second 
smallest, since Loch nan Losganan is shallower, narrower, of smaller 
area and volume. It is obscurely triangular in form, its axis running 
south-west and north-east, the apex to the north-east. It is situated 
at a high level, estimated at 1340 feet, amid moorland, rising gradually 
southward to Meall Fuarvounie (2284 feet). It is nearly one-fifth of a 
cc
