THE FRESH- WATER LOCHS OF SCOTLAND. 257 
that determined by the Ordnance Survey on July 8, 1893, viz. 351*1 feet. 
The temperature at the surface was 51°*0 Fahr., and at 8 feet 50°*5. 
Harperleas Reservoir (see Plate CXVI.) lies about 3 miles north-east of 
Loch Leven, on the boundary between Fifeshire and Kinross-shire, and is 
used by the Kirkcaldy and Dysart Waterworks. It is a small artificial basin 
covering an area of about 40 acres, but relatively very deep, the maximum 
depth of 41 feet being found close to the eastern shore, while one-third of 
the bottom is covered by more than 25 feet of water. The mean depth is 
estimated at 18 feet, and the volume of water at 31 million cubic feet. 
When surveyed on May 16, 1905, the elevation was 848*35 feet above the 
sea. The temj^erature of the water varied little, the following readings 
being recorded : —

Moll Beservoir (see Plate CXVII.) lies about a mile to the south-east 
of Harperleas, and has been recently made for the further supply of water 
to Kirkcaldy. Hallo reservoir lying between them had been emptied for 
repairs in February, 1905, and had very little water in it when visited in 
May, 1905. Holl reservoir covers an area of about 45 acres and is 
relatively deep, the maximum being 38 feet and the mean 17 feet, while 
nearly one-half of the bottom is covered by more than 20 feet of water. 
On May 16, 1905, the following temperatures were taken, showing a range 
throughout the body of water of 4° Fahr. ; —

Kilconquhar Loch (see Plate CXVIII.) lies close to the town of Kilcon- 
quhar, and about a mile north of Elie on the northern shore of the Firth 
of Forth. It is sub-circular in outline, and over half a mile in maximum 
diameter, covering an area of about 95 acres. It is a shallow flat- 
bottomed basin, the maximum depth being 6 feet and the mean depth 
4 feet, the volume of water being estimated at 16 million cubic feet. 
When surveyed on May 18, 1905, the elevation was 48*6 feet above the 
sea, as compared with 49*4 feet determined by the Ordnance Survey on 
March 19, 1894. The temperature at the surface was 61°*5 Fahr., and at 
5 feet 61°*0.
