The Board own 300 acres of the Balder area, and 300 acres 
of the Lune area, being simply the land on which the 
reservoirs have been constructed. Fully 95 per cent of 
both areas is moorland and the remainder hill pasture, 
there being no arable land and few plantations. There are 
about 50 or 60 houses and farmsteads on the Balder area, 
and 70 or 80 houses and farmsteads on the Lune area, 
wholly tenanted by what are known locally as fell-side 
sheep farmers. There are no special measures taken on the 
gathering grounds to prevent contamination, but the water 
if filtered. 
Ripon obtains its water supply from Lumley reservoir, 
with a gathering ground of 700 acres on Lumley Moor, 
between 600 and 800 feet elevation, utilising the Holburn, 
Craven Gill, and South Gill Becks, tributaries of the river 
Laver. Of the total area, 45 acres are owned by the Cor- 
poration, of which about 10 acres are plantations. Ditches 
are cleaned out, the watershed is carefully looked after, and 
the water is filtered. I have no information as regards 
farmsteads and cultivation on the gathering ground, which 
would seem to be suitable for afforestation. 
Harrogate obtains its water supply from two catchment 
areas : 
1. A gathering ground of 2720 acres on the head 
waters of Oak Beck, a tributary of the river Nidd, with 
four impounding reservoirs, namely, Scargill reservoir, drain- 
ing 1110 acres; Upper and Lower Beaver Dyke reservoirs, 
draining 1200 acres; and Ten Acres reservoir, tapping 400 
acres. This is moorland and rough pasture at 500 to 800 
feet elevation, and with an average annual rainfall of 28 
inches. 
2. Roundhill reservoir, on Pott Beck, a tributary of the 
river Burn, has a gathering ground of 3000 acres of moor- 
land, which adjoins the Leighton reservoir area, belonging to 
Leeds Corporation. 
No particulars have been obtained of these two areas, as
