not filtered. The impounding reservoir is 9 miles distant 
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.

is filtered before reaching the town.
