WATER CATCHMENT AREAS 227 



A weir built across the main stream diverts the water into 

 a leat or open conduit, which crosses the moor for many 

 miles. The water is filtered. See Journ. Roy. Sanitary 

 Inst, xxxiv. (1913). 



Ivybridge obtains its water supply from a new reservoir 

 on Harford Moor, Dartmoor, with a gathering ground of 

 414 acres, at 854 to 1200 feet elevation, all rough moor- 

 land and common lands. The Urban District Council own 

 only the site of the reservoir and land adjoining, which is 

 enclosed, about 8 acres. The Council have powers to enter 

 into agreement with owners, lessees, and occupiers of any 

 lands within the gathering ground for the execution of such 

 works as may be necessary for draining such lands, or for 

 more effectually preserving the purity of and collecting the 

 water. It has not been found necessary to make any 

 arrangements as to surface occupation. 



Torquay obtains its water supply from the Trenchford 



and Blackingstone valleys on an outlying spur of Dartmoor

The whole area is owned by the Corporation. Originally

 persons upon it ; but all dwellings and farm buildings have 

 been pulled down; and the greater part of the land is unused, 

 even for grazing, 559 acres being arable land allowed to 

 run to waste, while 799 acres are moorland.
