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 
on the eastern side between the Wrey Brook and the river 
Teign. The catchment area comprises 2331 acres, at 718 
to 1135 feet elevation, as follows :

The whole area is owned by the Corporation. Originally 
there were 19 dwelling-houses and a population of 119 
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. 
The section of 484 acres which is let as a farm is under 
severe restrictions, viz.: (1) The house and farm buildings 
lie off the catchment area, and drain towards Wrey Brook.
