250 FORESTS, WOODS, AND TREES 
part of the Loch Vennachar area, has been set aside to 
provide at a future date an additional water supply to 
Loch Katrine for consumption in Glasgow. In view of 
this, the Corporation in 1915 paid £30,250 to the Earl 
of Moray, and £2250 to the Commissioners of Woods, 
in respect of the Crown interests in the Royal Forest of 
Glenfinlas, or £32,500 in all, for freehold and wayleaves in 
Glenfinlas for additional waterworks, including obligation 
on the part of the owners to erect no buildings on the 
gathering ground of 9600 acres to the intended reservoir. 
The Gorbals Waterworks obtains its supply from the 
Brock Burn, about 6 miles south of Glasgow. The water 
is impounded into the Balgray, Ryat Linn, Waulkmill, 
and Littleton reservoirs, situated at 296 to 352 feet eleva- 
tion. The gathering ground, which is within the agricul- 
tural zone, is 2560 acres in extent. The Corporation 
have acquired only the water rights of this area. The 
water is passed through two sets of filters. 
No proposals have been made as regards the afforestation 
of either the Loch Katrine or Gorbals water catchment areas, 
neither of which is owned by the Glasgow Corporation. 
Helensburgh obtains its water supply from a small 
stream provided with a weir at 570 feet elevation. The 
gathering ground, about 800 acres of hill pasture, extends 
from this elevation up to 2100 feet, no part of it being 
owned by the Corporation. There are three storage reser- 
voirs, the water of the two largest of which is screened 
and filtered, and of the smallest is screened but not 
filtered. No other measures are taken against con- 
tamination. 
Alexandria, Bonhill, and Jamestown District Council 
obtain their water supply from Glen Finlas reservoir, with a 
gathering ground of 440 acres, entirely hill pasture, situ- 
ated between 1600 and 2000 feet elevation. Of the total 
area, which is without houses, farm-steadings, or planta- 
tions, the Council own 40 acres. No precautions are 
necessary against contamination of the water.
