THI^ FRESH-WATER LOCHS OF SCOTLAND. 
149 
feet; on tlie date of the survey (July 13, 1905) the water was a foot below 
the platform of the boathouse. The superficial area is about 38 acres, and 
the area draining into it exceeds a square mile. The maximum depth of 
1 1 feet was recorded between the large island and the western shore. The 
volume of water is estimated at 10 million cubic feet, and the mean depth 
at 6 feet. The basin is of a flat-bottomed character, about 62 per cent, of 
the lake-floor being covered by more than 5 feet of water. The surface 
temperature was 67°'9 Fahr. 
Loch of Skene (see Plate LIT.). — The Loch of Skene is situated about 
9 miles to the west of Aberdeen, and is a mile in length by two-thirds of 
a mile in maximum breadth. The superficial area is about 294 acres, or 
nearly half a square mile, while the drainage area extends to about 17 J 
square miles. The volume of water is estimated at 60 million cubic feet. 
The elevation could not be determined from bench-mark, but on the date 
of the survey (July 17, 1905) the water was 1-5 feet below the platform of 
the Dunecht boathouse ; the Ordnance Survey officers found the eleva- 
tion to be 274-8 feet above the sea on October 17, 1899. The loch forms 
a shallow flat-bottomed basin, the great majority of the soundings being 
taken at the maximum depth of 6 feet, the mean depth being nearly 5 feet ; 
in fact, about 73 per cent, of the lake-floor is covered by more than 5 feet 
of water. The surface temperature was 64°’2 Fahr.
