THK FRESH-WATER LOCHS OF SCOTLAND. 149 



feet ; on the 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 liasin 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 \ 

 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 0< 2 Fahr.
