The Grand Western Canal is to be found in the south West
peninsular serving Somerset and Devon and though navigable in places is
unfortunately isolated from the rest of the UK system. One end is accessible
from the Bristol Channel, which leads onto the
Bridgwater and Taunton canal and the other accessible from the Exeter
Ship Canal, but the passage between them is broken.
The original aim was to create and inland passage
connecting the Bristol Channel to the English Channel at Exmouth, avoiding
the need for a difficult passage around Lands End and proving a route that
could safely be used by small craft in all weather. A major cargo was likely
to be lime to the kilns returning quicklime for agriculture and building
purposes.
1795 saw the first proposals for such a venture, but it
was sometime later before any serious progress was made.
Work eventually started in 1810 with John Thomas as
engineer, with construction of the 2.5m middle section from Tiverton to
Lowdells to serve the lime quarries
and kilns. The decision made after construction commenced to cut the summit
cut 16 feet deeper, to avoid the
need of additional locks, which required another act of parliament in 1811.
This required a greater amount of earth to me moved, but in the longer term
would speed the passage of the canal by reducing the number of locks and
would also save money in terms of lock maintenance, though obviously the cut
itself would have to be maintained. The increased costs incurred by the
changes caused the project to stall as funds ran low and continued after
another Act of Parliament had been passed to allow an increase in the Tolls
charge for the passage of goods, work recommenced in 1812.
The need for quarrying at Holcombe Rogus
to cut
a path though rock led to a further slowing of progress, with some sections
also needing to be lined with puddle clay in order to seal leaks.
The canal opened 25th August 1814, the first
recorded cargo being coal from Lowdells to Tiverton.
Unfortunately traffic was less than anticipated and
profits were duly affected.
A second phase of development commenced in 1829 under
James Green, this time to develop a link to Taunton, James Green had
previously been involved in the construction on the
Bude
canal which used tub boats and inclined planes to cope with land
gradients and proposed a similar approach here, though Green propose the use
of vertical lifts.
The canal was partially opened in 1835, but completion was
delayed by technical problems with the lifts, Green
was sacked and W.A. Provis was asked
to review the works and propose solutions. Remedial work was instigated
including a steam engine at Wellisford to power the inclined plane and the
14 mile extension was open and fully functional on 28th June
1838.
The last commercial use was to carry road stone from
Whipcott quarry, of which about 7000 tons a year were transported until
1925, after that income from the
canal came from sheepwashing and the sale of water lilies that grew in it.
The Tiverton
Canal Preservation Committee was formed in 1962, with the intension of
preserving the canal where possible and the canal was passed from British
Waterways to Devon County Council,
who repaired a section of the canal with a butyl liner to prevent leakage
and opened it to unpowered craft in 1971, it is now a country park and
nature reserve.
The Somerset
section remains largely dry and continues in neglect.
