 Engineers, vol. 36, p. 447 (1910). 



Grange Urban District Council obtains its water supply 

 from a gathering ground of 120 acres at Newton in Cartmel, 

 Lancashire, between 600 and 800 feet elevation. The 

 Council owns 100 acres. The gathering ground is all moor- 

 land, and free from habitations except the cottage of the 

 attendant, the sewage of which is diverted by a pipe off the 

 area. There are two storage reservoirs at Newton in 

 Cartmel, and the water is filtered. 



Lancaster obtains its water supply from moorland springs 

 in Lee Fell, Dunkenshaw Fell, and Tarnbrook Fell, in the 

 north-eastern part of the watershed of the river Wyre. The 

 catchment area is said by Mansergh, in Journ. R. Soc. Arts, 

 vol 32, p. 872 (1884), to be 2700 acres in extent, at 850 

 to 1800 feet altitude, being scanty herbage on millstone grit 

 with numerous springs, so that the water supply is perfect. 

 As this supply is not derived from surface water, this catch- 

 ment area is not included in the total 66,412 acres of 

 gathering grounds of Lancashire, on p. 178. 



The Fylde Water Board, which supplies Blackpool, Fleet- 

 wood, and other places in Lancashire, has two catchment 

 areas in Bleasdale in the river Wyre watershed : 



Eiver Calder area, intake at Luddock's Fell, 2000 acres, 

 at 628 to 1520 feet elevation, without any plantations; no 

 part is owned by the Board. 



Grizedale Brook area, intake at Grizedale Fell, 1083 

 acres, at 395 to 1325 feet elevation. The Board owns 150 

 acres, including the sites of two reservoirs and some land 

 around them. There are about 50 acres of plantations in 

 the valley near the reservoirs. 



The whole gathering ground is rough moorland, unculti- 

 vated, and free from pollution, there being only one small 

 farm upon it. The water, which is stored in the Grizedale, 

 North Barnacre, and South Barnacre reservoirs, is passed 

 through straining chambers and sand filters.
