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 acres. 



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. : 



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.
