BATHYMETRICAL SURVEY OF 
LOCHS OF THE SLAINS BASIN. 
The little Sand Locli, lying close to the sea near Kirktown of Slains, 
was surveyed along with the other Aberdeenshire lochs. 
Sand Loch (see Plate LV.) is a small shallow basin situated amid flat 
and uninteresting surroundings close to the seashore between Aberdeen 
and Peterhead. It is a quarter of a mile in length, covers an area of about 
10 acres, and contains barely a million cubic feet of water. The deepest 
water is in the extreme north-eastern portion of the loch, where soundings 
in 4 feet were taken, shallowing thence to the southward. The surface 
temperature on July 15, 1905, was 67°*1 Fahr. 
From the following table it will be seen that in the sixteen lochs 
under consideration 879 soundings were taken, and that the aggregate 
area of the water-surface is nearly square miles, so that the average 
number of soundings per square mile of surface is 207. The aggregate 
volume of water contained in the lochs is estimated at 5762 millions of 
cubic feet. The area drained by these lochs is over 121 square miles, 
or about 28J times the area of the lochs.
