WATER CATCHMENT AREAS IN SCOTLAND 263 



gathering ground of 1963 acres in the steep stony hills at 

 the sources of Culter Water and west of Culter Fell. The 

 ground lies between 1150 and 2454 feet elevation, and is 

 used for sheep grazing, there being apparently little or no 

 risk of pollution. 



2. Springfield reservoir, 3^ miles east of Carluke, has a 

 catchment area of 1100 acres at 866 to 1029 feet eleva- 

 tion, mostly grazing. Part of the land, being under cultiva- 

 tion, is cut off by a bye- wash. 



3. Coldstream reservoir, the water of which is not used 

 for domestic purposes, has a catchment area of 650 acres, at 

 817 to 1009 feet altitude, all agricultural land. 



The Corporation own no part of these areas, except the 

 sites of the reservoirs. Part of the Culter gathering ground 

 could probably be afforested in the same way as the Camps 

 catchment area, which almost adjoins it. 



Lanark obtains its water supply from an impounding 

 reservoir on Tinto Hill in Carmichael parish, with a gather- 

 ing ground of 790 acres, situated between 1000 and 2317 

 feet elevation, entirely hill pasture and moorland, except 8 

 acres of plantations, and free from habitations or farm- 

 steadings. The Corporation own only the site of the 

 reservoir and filters, about 12 acres, and no special pre- 

 cautions against contamination of the water seem to be 

 necessary. 



Wishaw obtains its water supply from the Elvanfoot and 

 Gair reservoirs. The Elvanfoot catchment area — 6890 

 acres, between 1000 and 2403 feet elevation — is in the 

 Lowther Hills, comprising Burby Shank, Faugh and Laght 

 Hills, with Riccart, Law Rig and Meikle Shag, which are 

 drained by the Potrail Water and Potrennick and Pedden 

 Burns. It is partl);^sheep grazing and partly grouse moors. 

 Afforestation on simitar lines to that on the Camps area 

 may be possible. Gair catchment area, 395 acres, at 764 

 to 1083 feet altitude, is in the Benty Hillocks, west of 

 Lamington, and is all under sheep grazing. Particulars of 

 ownership of the two areas have not been obtainable.
