 from Warrenpoint. 



Newry obtains its water supply from Camlough Lake, 

 with a catchment area of 3407 acres, between 320 and 

 1385 feet elevation, situated in the townlands of Carrick- 

 bracken. Cross, Keggall, Ballinliss, Seafin, Tamnaghbane, 

 Ballynalack, Aghmakane, Sturgan, and Carrickcloghan in 

 Co. Armagh. The greater part of the area is mountain 

 pasture, with 100 acres of plantations ; but a considerable 

 portion is arable land with a good many dwelling-houses 

 upon it. As the area of the lake is 120 acres, with a 

 storage capacity of 600,000,000 gallons, it was supposed 

 at first that the storage capacity was sufficient to purify 

 the water without filtration ; and at present the water is 

 not filtered. Of recent years the conditions have changed, 

 and a filtration scheme which was submitted to the 

 Council by the Town Surveyor is held in abeyance by the 

 war. The Council own none of the catchment area.

 land, with 13 cottages upon it. These houses have earth 

 and dry closets. The water lying in the Drumbee bog is 

 conveyed both by pipes and by an open water course to
