WATER CATCHMENT AREAS 203 



Dewsbury and Heckmondwike Waterworks Board obtain 

 their water supply from four catchment areas as follows : 



Dunford Bridge Reservoir 1300 acres between 1100 and 1489 feet elevation. 

 Upper and Lower Windle- 



den Reservoirs . . 702 ,, ,, 1150 ,, 1500 ,, ,, 



Harden Reservoir . . 277 ,, ,, 1201 ,, 1560 ,, 

 Snailsden Reservoir . 209 ,, ,, 1369 ,, 1560 ,, 



Of the whole area, 2488 acres, the Board own only the 

 sites of the reservoirs, embankments, and other structural 

 works. The area is entirely moorland, without any cul- 

 tivation, and no measures are considered necessary against 

 contamination of the water, which is not filtered. " The 

 bacteriological examinations and reports are always satis- 

 factory." 



Barnsley has two catchment areas, viz. Ingbirchworth 

 reservoir, 2000 acres, between 800 and 1400 feet elevation, 

 and Midhope reservoir, 2000 acres, between 800 and 1600 

 feet elevation. The latter area is adjacent to the Langsett 

 area of Sheffield. Both gathering grounds, which are held 

 by private owners, are nearly all pasture or moorland, the 

 amount of arable land being very small. The Council, in 

 the spring of 1917, planted out 25,000 Scots pines and 

 5000 larches. The water is filtered. 



Sheffield obtains its water supply in part from the 

 adjacent moorlands on the west, which comprise three 

 watersheds as follows :

 tude, with 5 reservoirs, Upper, Lower, and Middle Redmires 

 reservoirs, at 1150, 1105, and 1068 feet, and Upper 

 and Lower Rivelin reservoirs at 698 and 672 feet
