WATER CATCHMENT AREAS IN SCOTLAND 251 
Dumbarton obtains its water supply from three catch- 
ment areas in the Kilpatrick Hills, aggregating 1273 
acres : 
1. Lochs Humphry and Fyn, 522 acres. 
2. Black Linn, 111 aeres. 
Both areas at 1051 to 1200 feet elevation ; hill grazing 
and grouse moor. 
3. Overton Glen, 640 acres, at 500 to 1050 feet 
elevation ; grazing and game preserves, slightly wooded. 
The Town Council do not own the areas, and have 
control over the water rights only. There are no farm- 
steadings ; and consequently no measures are needed, it is 
said, to prevent the pollution of the water. The Town 
Clerk does not think that it would be in the interest of 
the Corporation to acquire the ownership of the lands, look- 
ing at the price which would require to be paid for them. 
The Clydebank and District Water Trust is the local 
authority for the supply to the Burgh of Clydebank and the 
villages of Duntocher and Hardgate. There are five 
catchment areas, viz. : 
Catchment Area. Acres. Altitude in Feet. 
Loch Cochno é A F : 361 881-1082 
Jaw Reservoir : P : : 229 881-1170 
Greenside Reservoir : i : 855 830-1250 
Burncrooks Reservoir. ; ; 1070 820-1171 
Finland Burn : : 2 4 1190 820-1163 
all situated in the Kilpatrick Hills, mostly covered with 
peat, grazed by sheep, and without any human habitations. 
The water, otherwise pure, is stained a peaty colour, which 
is removed by the filters at Cochno. ‘The annual rainfall 
in 1912 was 51°48 inches. The lands of Cochno, Jaw, and 
Greenside reservoirs are held by payment of a yearly feu- 
duty; while the Finland Burn area is owned by the 
Trust for the purposes of the Water Supply Act of 1906. 
No planting scheme has been contemplated, as the ground, 
which is without any trees, is considered to be unsuitable 
for afforestation.
