Thames & Severn Canal
Thames & Severn Canal History
A Mr. Hill and a Mr. Rowland Vaughan published ideas on creating a waterway link from the River Thames to the
River Severn. If the plan had gone ahead it would have brought the canal era forward by over 150 years.
However, the waterway was never built though the idea was not forgotten.
Thomas Procter published pamphlets in London promoting a link between the Thames and the Severn. He proposed
the construction of a link which would give London access to the plentiful coal mines of south east Wales and
the Forest of Dean.
The astronomer and mathematician, Henry Briggs, was next to promote the idea of a cross country link and he is
often (mistakenly) credited with the first idea of such a route. He did a detailed survey but again nothing was
done. His survey was clearly not the same route which the Thames & Severn Canal takes today as he described
it as mostly flat terrain and easy to dig! Neither of these descriptions apply - even slightly - to the
Cotswolds through which the final route was constructed.
It was Mr. Hill (see 1600) who was next to try his luck. This time he even got
the personal backing of Charles I and he said he would survey a number of
routes and construct the most suitable with a full estimate of costs being
submitted before building would commence.However, it seems that Hill's much
talked about plans got no further than his initial pamphlet.
Next came Francis Matthew who had been a supporter of the King against
Parliament during the Civil War. He had been imprisoned by Cromwell but now
hoped to gain the support of the Lord Protector's government in a scheme which
would connect the Thames and Severn via the Bristol Avon. He got the support
and went ahead with a survey.
Matthew reported back to Parliament with the findings of his survey. Like all those who'd gone before him his
report centred on the route without any mention of the difficult terrain. It seems nobody had ever wondered how
an artificial waterway would get past hills or cross rivers. Nobody ever thought about the differences in
ground conditions or the problem of water supply. Instead, Matthew tried to win good favour with Cromwell by
emphasising the profits that would be gained if the state built and took control of the waterway.The Bill was
passed by the House of Commons but failed to get past the more influential Lords.
After the restoration of the Royal Family the whole country regained financial confidence and river
improvements were being made in many areas. Francis Matthew re-appeared on the scene with a new scheme (on an
old theme) which he claimed had the full backing of the King himself. This time the Bill past two readings in
Parliament but was then heard of no more.
Three new Bills were put to Parliament (two of them on the same day) proposing a Thames and Severn link but
none of these resulted in an Act being obtained.
Francis Matthew was not a man who gave up easily. For a third time he put a Bill forward to build what would
have been Britain's first ever completely artificial waterway. Somewhat strangely, Matthew's backer in the
House of Lords was the Earl of Bridgewater. Little did anyone know that it would be the Earl's great grandson
who would eventually build the country's first ever totally independent artificial waterway nearly 100 years
later. Matthew's Bill also had the backing of a number of other Lords who had backed the various similar
attempts in the past. Unfortunately for Matthew his Bill failed to get past the first reading yet again though
he still continued with his promotions for a number of years.
Matthew tried once again to raise interest in a cross country water link. This time he proposed an upgrade for
the river Avon from Bristol to Malmesbury where a 5 mile artificial cut would link with the Thames at Lechlade.
By now he even saw the importance of locks (or saffes) and he included water supply schemes. It seems that
Francis Matthew had been born 100 years too early, once again his proposals were turned down and he was never
mentioned in canal history again.
Over the next hundred years many rivers were upgraded and eventually artificial cuts were
opened at various places around the country. One such cut connected the Gloucestershire town of Stroud to the
When the Stroudwater Navigation opened the idea of a cross country link towards the River Thames was rekindled.
However, the main backers of the route were not local men but traders from far away to the north in the Severn
Valley. These were the businessmen of Shropshire who transported coal and iron from places like Coalbrookdale
and Shrewsbury on the higher reaches of the river. They needed a route to London which could replace pack
horses and the often unusable roads.
An Act was finally passed enabling the construction of a canal which would link the River Thames to the River
Severn. It was to be a broad canal able to take Severn Trows and Thames Barges. A second proposal also went to
Parliament applying for the right to bypass the troublesome upper Thames between Abingdon and Lechlade but this
was refused. The River Thames in this region was often shallow and unnavigable. Flash locks (rather than
canal-style pound locks) continued to be used to keep mill owners happy - and barge owners very unhappy.
Robert Whitworth did the original survey for the Thames & Severn Canal but Josiah Clowes
was employed as Chief Engineer with James Perry as superintendent. The appointment of Clowes probably
emphasises the involvement of backers from the iron industry in Shropshire as Clowes was involved in many of
the canal projects in that area. As with virtually all canals the main bulk of labourers were professional
"navvies" who travelled from canal to canal. However, the Thames & Severn Canal was also built by local men
as the route was constructed at a time of high unemployment in Gloucestershire due to a depression in the wool
The canal was opened from the Stroudwater Navigation to Daneway on the west side of the Cotswold Hills. The
long Sapperton Tunnel which would carry the canal through to the east side of the hills took 3 more years to
On July 19th His Royal Highness, King George III, visited the eastern end of the unfinished Sapperton Tunnel.
The cutting leading to the tunnel has been known as King's Reach ever since.George also visited the western end
of the tunnel and the junction at Wallbridge in Stroud where the Thames & Severn Canal met the Stroudwater
The Thames & Severn Canal opened throughout, running for 30 miles (including a short branch to Cirencester)
from the River Thames above Lechlade at Inglesham to the Stroudwater Navigation in Stroud. It was the first of
the 3 southern cross-country routes to open, ahead of the Wilts & Berks and Kennet & Avon, but it never
came close to the success of the other two waterways. In fact, it has been said that at best the Thames and
Severn Canal was no more than a complete failure! Sapperton Tunnel on the summit level was the 3rd longest it
ever built in Britain at over 2 miles long but it caused many a headache for the company because it (and some
of the locks on the east side of the canal) had been built on an unequal level. This and numerous other
problems were mainly caused by very poor workmanship during construction. The contractor, Charles Jones, had
often been too drunk to supervise the work. Eventually he had been sacked and replaced by John Nock and Richard
Sheppard but this had been done too late and much of the damage had already been done. The canal also suffered
badly from water shortages which were made worse by the leakage of up to 3 million gallons a day! This was due
to the oolite rock (a porous limestone) which the canal bed had been built on.
Water problems proved to be so bad on the eastern side of Sapperton Tunnel that a pumping station was built at
Thames Head to supply the thirsty canal with water from the River Thames. However, the pump took four years to
build and canal trade suffered badly throughout this time. Matters were made worse due to the poor navigational
state of the upper Thames, boatman were reluctant to struggle along the poorly kept river and thus canal
traffic never reached its expected volume. As if things weren't bad enough, poor trade was soon turned into
very bad trade when a much shorter route between the Midlands and London opened less than one year after the
Thames & Severn. Within 12 months of opening, the canal's main reason for being built - as a cross-country
link to the capital - was completely lost.
The one part of the canal which was well used was its western end between Stroud and
Brimscombe. A large wharf was built at Brimscombe and for a while it prospered as a transhipment centre where
cargoes would be transferred from Severn trows into Thames barges or narrow boats. Most boats were not pulled
by a horse but hauled by gangs of men. Cargoes included wool, building materials, timber and salt as well as
coal from south Wales and the Black Country and metal products from Shropshire.
Five "dwellings"were built on the canal though these were no ordinary canal cottages. The buildings were unique
to the Thames & Severn Canal, they were constructed completely round (like sail-less windmills) and had
curved windows to give the occupant an all-round view. Each of the buildings (known as "roundhouses") had 3
storeys with just one room on each floor. These consisted of a stable on the ground, living quarters on the
middle floor and a bedroom on top. Although the buildings were very useful in canal terms, they were very
unpopular with those who had to live in them. There is even a famous story about a canal employee's bride-to-be
who refused to live in one of them unless the company made alterations - amazingly, they did! The house was
altered by putting the stable outside and adding a separate kitchen to the ground floor. The design of the
roundhouses was dropped after the 5th was completed and more traditional cottages were built thereafter. All 5
roundhouses survive today, amazingly four of them are still used as houses while the fifth is
derelict.Coincidentally, the derelict one is the one which the company redesigned for the bride-to-be.
The neighbouring Wilts & Berks Canal company opened a branch named the North Wiltshire Canal which
connected the Wilts & Berks Canal to the Thames & Severn Canal at Latton, near Cricklade.This new canal
provided a better route for through traffic from the Thames & Severn Canal to the River Thames because it
avoided the troublesome upper Thames by joining the river much further downstream at Abingdon. It also opened a
route to Swindon and to the Kennet & Avon Canal further south. However, the North Wiltshire Canal was built
to narrow dimensions, preventing full sized Thames & Severn barges from making the trip.
The Thames & Severn canal's owners joined forces with the Gloucester & Berkeley Canal and the
Stroudwater Navigation in their opposition to a Bill put forward by the newly formed Stroud & Severn Rail
Road Company which wanted to build a railway alongside the whole length of the Stroudwater Navigation's route.
The Bill was successfully opposed.
During the 1820's and 1830's the Thames & Severn company made of number of modifications to the canal. This
included repairs to the pounds which still suffered badly from leakages on the west side of Sapperton. One
report said water was rushing out of the canal as fast as it could be fed in. Also at this time, the flight of
locks leading up to the west side of the summit at Sapperton were modified, they had been capable of taking
trows up to 90 feet long but these vessels had never been used in any great numbers this far up the route. The
locks were shortened to 70 feet (the length of a working narrow boat). This modification saved around 20% of
The Thames & Severn Canal put forward a Bill to turn themselves into a railway company. This was brought
about when a newly formed company, the Cheltenham & Great Western Union Railway, proposed to build a track
running alongside the canal from Cirencester to Stroud. At the same time another railway was proposing to run
across the Cotswolds, this was to be - wait for it - the Cheltenham, Oxford And London And Birmingham Union
Railway! The C&GWUR lost the battle to run a line alongside the canal but the Thames & Severn also lost
the battle to convert itself into a railway. The CO&L&BUR won the day andconstruction began.
The railway line took 9 years to complete and in that time it had been taken on by Great Western Railway. As
soon as it opened, the Thames & Severn Canal began to take in water - so to speak!
The Thames & Severn Canal, now struggling badly due to railway competition, paid out its last dividend to
Faced with more and more proposed railways the Thames & Severn Canal once again put forward its own Bill to
become a railway company. They hoped to link the railways near Oxford to those near Stroud, making use of the
ready made tunnel at Sapperton for a single line track. This would have meant draining the canal, cutting off
important water supplies used by the Stroudwater Navigation and Gloucester & Berkeley Canal. The Thames
& Severn company planned to get around this by piping water from its pump at Thames Head. It is said that
the water supply proposal is what cost the Thames & Severn Company their Act of Parliament because there
was huge opposition against using Thames water to supply the Severn Valley.
A man named Richard Potter, a former Director of Great Western Railway, began to buy up the shares of the
Thames & Severn Canal with the sole intention of gaining control and turning the canal into a railway to
provide competition for his former company. He eventually acquired around 80% of Thames & Severn Canal
Potter and the Thames & Severn Canal company (which he now controlled) proposed to build a railway from
Cirencester to Stroud which would link with other existing railways. Once again the Stroudwater, Gloucester
& Berkeley and Wilts & Berks canals opposed the scheme though Potter strongly urged them to join forces
with him.They all refused and Potter was defeated. He was quick to wash his hands of the canal (which he'd
never wanted) by selling his shares to the Great Western Railway for a healthy profit. This meant that the
canal was safe from being turned into a railway but was now owned by a railway! GWR did not close down the
waterway, objections from the neighbouring navigations would have been too strong to get away with that.
Instead the railway simply left the canal to decay. Because of this navigation became very difficult so the
connecting canals proposed to join forces and lease the canal for 21 years. Great Western Railway agreed to the
lease but only at a ridiculous price which the canals could not afford.
After many complaints from neighbouring canals and canal carrying companies the Board of Trade inspected the
Thames & Severn Canal. Finding it to be in a very bad state they warned Great Western Railway that work
must be carried out immediately to bring the canal up to a reasonable standard. However, GWR ignored the board
and nothing was done.
Great Western Railway announced it was to close 26 miles of the Thames & Severn Canal, leaving just 4 miles
intact. Local traders, boatmen and even the local councils petitioned MPs. Great Western Railway were stopped
from closing the canal on the grounds that there were plenty of people and connecting canal companies willing
to keep the route maintained.
Due to all the pressure an Act was passed allowing the setting up of a Thames & Severn Canal Trust
comprising mainly of local people with the help of other canal companies such as the Gloucester & Berkeley
and even the distant Staffordshire & Worcestershire. The Act included proposals to make the upper Thames
easier to navigate but this was never done. So much work needed to be done on the canal that during the
following 5 years it was only navigable throughout for 3 months.
The Thames & Severn Canal was taken on by Gloucestershire County Council who (before allowing traffic on
it) rebuilt 2½ miles of the summit level to the east of Sapperton Tunnel. The tunnel and the summit level had
leaked permanently since the day the canal was built.The approach to the tunnel (King's Reach) was lined with
The canal was fully re-opened but traffic never recovered even to the level of what had been very low usage in
the first place.
After years of little use, ever increasing water supply problems and high maintenance costs all of the eastern
side of the canal was closed from the junction into the Thames to Puck Mill Wharf (2 miles west of Sapperton).
This also included the closure of Sapperton Tunnel.
The remaining part of the route from Puck Mill Wharf, westwards, down through the Golden Valley to Stroud was
also closed and the whole canal was left to become dry and derelict.
Abdela & Mitchell (a boat building company) continued to build boats on the canal even after the route was
officially closed in 1933. Their yard was at Hope Mill Lock, west of Brimscombe, from where finished craft were
delivered by land as there was no way they could sail down the disused canal. This business ceased at the
beginning of WW2.
The former busy transhipment port at Brimscombe was demolished to make way for a factory. The basin had a
number of original buildings around it and an island in the centre used for keeping important cargo away from
would-be thieves. After the demolition only the old wharfinger's house was left standing. A plaque was placed
on a wall "commemorating" the site of the basin. By this time the whole canal was overgrown and completely
The classical eastern portal of Sapperton Tunnel (near Coates) was fully restored. In the years since, the
canal restoration trust has run trips into the tunnel though the bore has been completely blocked for many
years due to rock falls deep inside.Coates roundhouse, which is situated near to the tunnel, was later rescued
from the threat of collapse.
An active effort was made to start restoration work on the whole route which would probably be more popular
with tourists than it ever was with traders. The "Stroudwater, Thames and Severn Canal Trust" (later renamed
the "Cotswold Canal Trust") began restoring the Thames & Severn Canal and the adjoining Stroudwater
One of the most sensitive areas on the whole route is at Daneway where 6 remaining locks climb up to the
western side of the summit just before Sapperton. A three year project was begun by the canal trust and the
British Trust For Conservation Volunteers (with help from Gloucestershire Wildlife) in which 2 locks would be
cleared during each of the following 3 winters. This had become vital because the locks were in danger of being
devoured forever by mother nature.
Also, the first location to be restored on the eastern side of the canal was Cerney Wick
Lock to the north of Cricklade.
A group of volunteers on a project known as "Dig Deep"restored the structure of Boxwell Spring Lock near South
Cerney. It took 2 years of volunteer's time to rebuild the lock walls. A lot of work was also done by the canal
trust volunteers in this area in restoring and maintaining the towpath.
The "Dig Deep" project (run by the Waterway Recovery Group) next turned their efforts onWildmoorway Lock (just
north of Cerney Wick). Work on this lock was also expected to take several years.
In the area which the "Dig Deep" project and other restoration work was taking place, between Cricklade and
Cirencester, the busy A419 was to be upgraded right alongside the Thames & Severn's route. The canal trust
were very worried that the new road would not accommodate the canal and a public inquiry was set up to look
into the problem. As a result of this the Highways Authority were told they must plan their new road with
provisions for a canal crossing which would not hamper the canals restoration or obstruct future
navigation.This all sounded fine but the inquiry went on to say that the building of the road bridge must be
paid for by the canal trust. This would have been an enormous amount of money for the struggling trust to have
to bear - motorway bridges do not normally come under a canal society's budget!! A long political battle began
which even had government colleagues putting forward contradicting views. The minister for the environment said
he was very much in favour of restoring the canal while the transport minister announced that public funds
would never be used to pay for a canal bridge.
Meanwhile, over at the western end of the canal the authorities were much more friendly. The
Stroud bypass (also part of the A419) was built with navigable bridges and the local council restored a number
of old hump backed bridges which had been flattened. The council also agreed to rebuild a bridge on the A46 in
the centre of Stroud when they changed the road layout above the canal line. The canal had previously been
culverted beneath the road.
In September the western portal of Sapperton Tunnel was restored to its former glory. The
rather plain looking derelict portal was transformed into its original gothic style. By this time many locks
along the line had been cleared out and repaired, Wallbridge Upper Lock in the centre of Stroud became the
first to be fully restored with gates installed and water flowing through.
With the A419 Latton bypass now under construction the canal society were becoming
increasingly worried as no settlement had been agreed over the building of a canal bridge. Gloucester County
Council made the surprising move of offering to donate £250,000 towards the building of a bridge. The reason
this was surprising is because the bridge would not be in Gloucestershire but in neighbouring
Wiltshire.Gloucestershire realised that a fully restored canal would bring them lots of benefit but this was
not the first time GCC had come to the canal's rescue. Back in 1900 they bought the whole canal a restored it
following GWR's attempts to close the route. Support for the canal's restoration was growing all the time,
hundreds of people had written to their local MP and each of the MP's, along with every local authority and the
Environment Department pledged their support to the canal.
In May there was a general election and the Conservative Party were ousted from government with the Labour
Party taking power for the first time in 18 years. Immediately there was a change for the Thames & Severn
Canal with the new government instructing the road contractors to include a navigable culvert under the A419.
In July, just 3 days after the announcement was made, road works began on the site of the culvert showing just
how close the canal had come to being blocked. The culvert under the dual-carriageway was to be 100 feet long,
with a 12 feet 6 inch waterway width and 4 feet 6 inch towpath.Water depth would be 4 feet 6 inches and there
would be 8 feet headroom. The building of the culvert opened the way for the canal's full restoration.

Thames & Severn Canal Route
The Thames & Severn Canal left the Stroudwater Navigation at a basin in Stroud. The
junction was to the south of the town at Wallbridge just west of the A46 road bridge. I visited this area in
1996 at which time the canal was culverted under the A46. Access to the towpath could be gained from the left
side of the bridge (heading west) where there was a gap in a dry-stone wall. A house which the towpath runs
alongside was the former Stroudwater Navigation Company HQ. The canal was overgrown when I was here and the
towpath was missing in parts but there was plenty of water in the canal. It made a lot of noise as it splashed
over Wallbridge Lower Lock which had been converted into a weir. Just beyond the lock on the towpath side
(south) is a fenced off area belonging to the local water authority. The land now used as a parking area is the
site of Stroud basin. Back at the A46 the canal reappears from the culvert on the east side of the road and
passes a short section of derelict land which was being cleared by society members when I was here, just beyond
the next road bridge is Wallbridge Upper Lock. Until recently this lock had spent well over 100 years in the
shade, hidden below a road bridge which led to a nearby railway yard. In years gone by local people used the
bridge as a diving platform and used the lock as a swimming pool!I found the lock to be completely restored
with gates and lock beams, the old bridge had been removed.
The canal begins its 30 mile unnavigable journey eastwards with a 3 mile stretch into
Brimscombe. Until recently leaving Stroud was said to be a dreary walk with the canal full of weeds, factories
and garages backing onto the towpath. The factories and garages remain but the canal hand towpath have now been
cleared. The Stroud bypass has been built with provision for boats to pass through though the canal was still
culverted in this area to the east of the town when I was here in 1996. Near the point where the new bypass
crosses over is a brand new shopping mall. As the canal route passes under the new road it also passes under
the railway viaduct and over the River Frome. The old A419 is also never far away to the north.
The first of 5 locks on route to Brimscombe is Bowbridge Lock which has been dammed to keep
water in the pound above it. The River Frome is very close on the north bank though at the lock it disappears
under what was once a large mill complex, this has now been converted into houses and flats. Past the lock, in
the days before it was damned, the route had reverted to a dry ditch. One of the first jobs the restorers took
on (in the mid 1970's) was to dredge this length and re-water it.It is now a very pleasant stretch.
The canal curves as it travels to Griffin's Mill Lock and then Jubilee Bridge which was
built (in iron) to celebrate Queen Victoria's fiftieth year on the throne in 1887. Ham Mill Lock and bridge
come next, it was here in 1933 that the last boat ever to use the canal commercially was unloaded. The bridge
at the lock was beautifully restored recently by Gloucester County Council.
Bagpath Bridge is next, followed by a gentle south easterly curve towards Hope Mill Lock.
This lock has long since been concreted over with buildings and a road on top of it - just one of many major
headaches for the restoration trust. The canal route disappears for a short while here but when it re-appears
it continues east towards Gough's Orchard Lock near the site of Brimscombe mills. From here into (and through)
Brimscombe the route has long since been buried under roads and buildings.
Brimscombe was a fairly important port where goods were transhipped between Severn Trows,
Thames Barges and narrow boats. There is no sign of the port today though there was once a number of buildings
here including a weighing machine and a coal store built on an island. Only the wharfinger's cottage and a salt
store had survived when the author of my reference book visited the area but I believe even these have now
gone. Part of a factory (formerly Benson's - now Fenworth's) was built on the basin though this (I believe) has
now been replaced by a car park (also belonging to Fenworth's). There is a small plaque on a wall of the
factory commemorating the once busy port. The canal reappears down a small lane between the factory and the
river Frome. Here there is a row of elegant iron railings and a bridge. At the end of the grounds of the
factory is the site of Bourne Lock which was the furthest lock capable of taking Severn Trows, it has been
The locks from now on are all much smaller than those west of Brimscombe. Near Bourne Lock
there is (or was until recent years) a blue door in a wall which was mentioned as far back as 1911 in Temple
Thurston's book "Flower of Gloster". Just past the lock the railway line crosses the canal on an arched
viaduct. Next the canal reaches Beale's Lock which is said to be in good condition though all I saw around this
area was lots of weeds. The site of Brimscombe railway station is very close by, steam trains used to use the
canal to top up their water supply while waiting at the station.There is a road bridge over the canal by the
lock but it has been flattened and the canal is very overgrown.
Next, after passing a culvert under the towpath, the route arrives at St. Mary's Lock. The
stretch between Beale's and St. Mary's locks is about ½ a mile long and the walk is said to be one of the most
attractive on the canal though when I saw it (1996) it looked much like any other totally unkempt, weed covered
footpath. The railway crosses back overhead and then Ile's Mill Lock is reached. Just past here the route has
been wiped out with 4 garages sitting on its filled in bed at the site of Ballinger's Lock.
A little further east the route enters Chalford, one of the largest villages in Britain,
which has many old buildings and warehouses. In the centre of the village is Chalford Wharf and the first of
the 5 roundhouses. This one (during the 1970's) was a museum though it is now a house once again. In front of
the roundhouse, on the old wharf is some old sluice gear from Sevill's Mill (which used to be a mile further
east). Chalford Mill stands down the embankment from the roundhouse complete with its mill pond - a pretty
scene. Nearby is the former company's Arms Inn which was built in the 1400's. East of the wharf was Chapel Lock
but it was filled in during 1964 and the canal leaves the centre of Chalford via a culvert. The route reappears
on the east side of the village, the A419 crosses the canal and runs to the south from now on. A minor road
(heading towards Frampton Mansell) runs along the north side of the waterway as it travels up the beautiful
Cotswold's Golden Valley. The site of Chalford railway station (on the south side of the canal) is high above
Bell Lock which was partly covered by the main road (A419) when it was widened in the 1930's. Before the road
was widened the canal bridge caused a sharp zigzag in the road which was narrow and dangerous even in those
days! Past Bell Lock there are now some holiday homes by the canal side where Chalford skittle alley used to
stand. Bell Lock and Red Lion Lock were (of course) both named after nearby pubs though Red Lion Lock is about
200 yards past its pub which is (and always was) called The New Red Lion Inn. The pub stands sideways-on, the
tiny River Frome flows between the pub and the canal and a small footbridge crosses over the river to give
access to the towpath.
Red Lion Lock bridge has an inscription celebrating the appointment of Clowes as the canal's
engineer. The small hump backed bridge is the only such footbridge still standing in the Golden Valley. It once
carried an ancient track which climbed steeply up either side of the valley though now there is no track and
only pleasant gardens belonging to pretty cottages which line the canal to the north while the railway runs
close to the south.The gardens use the River Frome as an ornamental feature while more expensive houses stretch
up the valley side giving Chalford its image as an English "alpine" village. Alongside Red Lion Lock are a row
of small cottages whose front doors open onto the towpath and lock side.The lock itself had been cleared by the
canal trust just days before I visited the area in May 1996. On the lock masonry there is another inscription,
this time engraved by the man who was contracted to build the lock.
As the canal continues up through the Golden Valley, Chalford's narrow old high street
continues to run parallel a little way to the north.The canal passes the shrunken pond of Sevill's Mill which
once covered the valley floor. This caused the canal to be squeezed onto the valley edge and the railway has a
sort of ½ viaduct here where it crosses the former mill pond. Around the next bend is Golden Valley Lock which
hasn't stood the tests of time as well as some of the others on the route. A building near the lock was once a
mill and 2 different pubs but it is now a house. A minor road linking Chalford to the A419 crosses at this
point, the area is known as Valley Corner. The next stretch passes the site of Ashmead's Mill which also once
stretched across the valley floor, near by is a large Victorian waterworks which was a pumping station
supplying water to Chalford and the canal from a stream named the Black Gutter.
The canal now reaches Bakers Mill Lower Lock with Bakers Mill above the canal near the tiny
road bridge. The fine old Cotswold mill looks more like a large house rather than the traditional (younger)
square buildings with large chimneys etc. Bakers Mill was owned by the Twissell family who first made cloth and
later ground corn. The Thames & Severn Company bought the adjacent mill pond and some surrounding land and
built a small reservoir which is situated beside the canal on its northern bank. The reservoir now looks like a
large natural pond and has become a wildlife haven. The area has been described as "idyllic in summer" - I can
vouch for this. The pound between Bakers Mill lower & upper locks was one of those which suffered worst
from leakages. The canal was fed by Bakers Mill reservoir as well as a number of local springs and this extra
water was certainly needed as the section between the next 2 locks (at Puck Mill) is the stretch which was once
said to be losing water as fast as it could be fed in. Puck Mill Lower Lock is followed by Puck Mill Upper Lock
which became the eastern terminus of the canal in 1927 when everything past here was closed down. The stretch
around Puck Mill is now owned by the canal trust who maintain it as an example to the numerous other private
owners on the route.
Whitehall Lower Lock follows but there is quite a long pound before the Upper Lock which is
actually the bottom lock in the flight of 7 which take the canal up to the 241 feet summit level at Daneway.
The 7 derelict locks all come within ½ a mile, the second is Bathurst Meadow Lock and then come Siccaridge Wood
Lower, Middle and Upper Locks. All the locks in the flight were shortened in the 1820's from 90 feet to 70 feet
to cut water usage by 20%. The upper locks also had side ponds added (on the southern side) which were used as
mini reservoirs and can still be seen in the undergrowth. Just before the top lock is the top most side pond
which was also used as Daneway Basin. The wharfinger's cottage has been modernised and is now a private house
though the basin has long since been flattened. However, it can still be defined and the winding hole near its
entrance has survived. Just above the basin is a road bridge carrying the minor road to Sapperton with the
Daneway Inn just beyond the bridge. Despite the canal being disused and mostly dry, the walk from Chalford to
Daneway, up through the beautiful Cotswold's Golden Valley, is as good as canal walking ever gets.
The car park of the Daneway Inn is built on the site of the top lock which was immediately
beyond the road bridge. Surprisingly, the bridge is a listed building. The Inn was built in 1784 and was
previously called the Bricklayer's Arms though prior to 1807 it belonged to the canal and was used as lodgings
for canal navvies. The summit level of the canal, now looking overgrown and miserable, swings south eastwards,
crosses the River Frome (which has been culverted) and after a few hundred yards passes a derelict tunnel
keepers cottage just before arriving at the recently restored gothic-styled western portal of Sapperton Tunnel.
The tunnel is the 3rd longest on Britain's canal system and took 5 years to construct. It is 14 feet wide for
the most part though some parts are only 12 feet wide. Leakage and bad workmanship caused continual problems
and the soft earth above caused even more. The walls bulged beyond belief as water built up in the soft rock
behind them. The tunnel is now blocked though public trips are taken frequently into the eastern end. The path
above the tunnel can be followed easily by looking out for the line of mounds from the tunnel spoil heaps.
Legging through the tunnel could take up to 5 hours depending on the current. The east portal, which was
restored in 1975, is in Hailey Wood near Coates. It was built in a much more classical style compared to the
western end, it's facade includes niches intended for statues, one of which was for Father Thames and the other
for Madam Sabrina though it is thought that no statues were ever installed. On the hill just above the portal
is Tunnel House which was used to house the tunnel builders though it is now a pub. Its interior was completely
destroyed by fire in 1952 but has been well restored.
The tunnel is sign-posted from the Coates to Tarlton road along a track. The section to the
east of the tunnel (King's Reach) is the portion which was rebuilt by Gloucester County Council when they
bought the canal around 1900. They re-lined the bed with concrete in the deep cutting leading to the tunnel but
decided not to repair the leaking stretches further east. Tarlton (road) Bridge is the next structure of note,
this had been dammed with wooden stop planks when I was here in 1996 to keep enough water in the tunnel for
boat trips. East of the bridge the canal is completely virtually all of the way to the Thames at Lechlade.
Within about 200 yards of Tarlton Bridge is Coates roundhouse. This was the roundhouse which the company agreed
to alter for the keeper's bride-to-be. The ground floor stable was made into a living room and a kitchen was
added. This is the only roundhouse which is now derelict, the staircase to the upper floors has collapsed, and
the floors (which were said to be shaky in 1971) have now gone completely. Demonstrating how desperate the
canal company were to fill the leaking waterway, the roof of the roundhouse used to be inverted to catch rain
water! Sadly the roof has now also gone. A restoration report in 1995 said the roundhouse had been rescued from
collapse by canal trust volunteers.From what I could tell, they got there just in time. Compared to the
beautiful Golden Valley the east side of the canal seems somewhat bleak as the canal runs along a hillside
looking weedy and dry. However, there is actually a lot of water under ground hereabouts as it is within ½ a
mile of here that the springs emerge to form the River Thames. Not far from Thames Head and close to the canal
is the site of the iron-age Trewsbury Fort which more recently has been used as a quarry.
Both the River Thames and the Thames & Severn Canal can be reached from Thames Head
railway bridge, 3 miles south of Cirencester, on the A433 (the old Roman Foss Way). The canal crossing is just
a few hundred yards north of the railway bridge but the A433 has been realigned at the crossing point and the
old Thames Head canal bridge is now on a quiet side road leading to some cottages which were once on the main
road. The best way to see the bridge is to stand on the new A433 facing west at the crossing point. In effect,
if you do this you will be standing about 6 feet above the former water line. The old A433 runs right alongside
the new road but at a higher level thus the eastern parapet of the old bridge can easily be seen right in front
of you. It has a plaque on it indicating the significance of this seemingly misplaced bridge wall. The new main
road is built at the level where the top of the bridge's arch began. If you get very close up to the bridge you
can peek through the very top of the arch to the dry canal bed below. The new main road has no bridge, it was
built straight over the canal and on the road's eastern side the canal is dry and hardly recognisable at all.
The Great Well (63 feet deep) of the former pumping station which supplied water to the canal can still be seen
just past Thames Head, 200 yards east of the old road bridge.The pump house itself has gone though the keeper's
house still stands and is used as a private residence.
The canal now winds north eastwards towards Siddington, south of Cirencester. On the way
there Smerrill Aqueduct used to cross over the Cirencester to Kemble road (A429) but it was demolished during
another road widening scheme many years ago. It was a single-arched structure which - like the rest of the
canal - also leaked! The aqueduct was actually part of a huge embankment with a tunnel cut into it for the main
road to pass through. A lot of the embankment was demolished during yet another road realignment scheme but
this now makes it easier to look at the site as the original main road (which went through the aqueduct) is now
a lonely side track. The stonework at the base of the west side of the aqueduct can be seen on the road
side.Above the road, the severed embankment is thick with undergrowth and trees. On the east side of the site
there is nothing but open space where the embankment used to continue. It now restarts about 100 yards further
east, on the far side of the new realigned A429. The site of the aqueduct is easily detectable near the road
junction to Coates though once again you first have to detect the former line of the main road. Between here
and Siddington the canal alternates between a dry ditch, a wet ditch and nothing but grassy fields. At one
point it runs alongside the minor road from Ewen to Siddington and almost looks like a canal though the water
is very shallow and the towpath is well covered by huge trees. Further along the same road the canal crossed
from one side to the other but the crossing is now marked only by two gates on either side of the road, each
leading into grassy farm fields. The Cirencester Arm left the main line and ran north for about a mile from the
junction house at Siddington village. The junction and the top lock of the Siddington flight are now on private
land but they can be seen from the hump backed bridge which carries a minor road over the dry lock flight in
the centre of Siddington. Immediately north of the junction the Cirencester Arm vanishes beneath a house but
the dry line of the arm can be picked up from a road bridge which crosses the route to the north of the
junction. Beyond here the arm is filled in with rubbish dumped right next to a notice forbidding the dumping of
rubbish! North of this there is a few hundred yards of dry though deep canal bed. Over to the west, across a
field, the former Midland & South West Junction Railway ducks down into a cutting. The towpath is said to
be clear on this stretch though the canal abruptly disappears under an extension to an industrial estate. The
canal's former route passes right through the centre of the Somerfield supermarket which has obliterated all
traces. The line of the canal can be found again at the site of Chesterton Lane road bridge. The former
Cotswold District Council offices are alongside the former bridge, the Cotswold Canal Trust now use part of the
building as their HQ. Steps lead down the north side of the bridge onto what was once the Cirencester Arm.The
current footpath is the former towpath, the canal was on the west side of the path. After a while the canal's
route is lost beneath the new A419 bypass and other roads and buildings. At the north end of the arm only the
wharf house at Queens Hill remains. The triangular shaped basin was filled in, in 1971. It was situated near
Whitworth Road (named after Robert Whitworth who surveyed the Thames & Severn Canal).
Past the junction in Siddington the main line begins its descent to the Thames via the 4
Siddington Locks. As I have mentioned, the top lock is on private ground but the next two locks are still
visible.In fact, they had been cleared of rubbish and weeds not long before I saw them in 1996. The fourth lock
will provide an interesting test for the restorers however as the garden of a house has been built on top of
it! Eagle-eyed canalcoholics will spot that part of the lock masonry is now part of the garden wall. However,
the outside of the wall was previously the inside of the lock. Past the bottom of the flight the towpath has
recently (1995) been restored for walkers by the Ramblers Association and the hump backed Cowground Bridge
should also have been restored by now. The canal travels on a slight embankment as the towpath opens out and
fields can be seen all around.These fields were once water meadows long before the existence of the canal.
A little further south are another 3 locks to the north of South Cerney near the minor road
to Cirencester. The top lock has a lock keeper's cottage alongside it though the lock itself has been
buried.Across the minor road the canal disappears completely in a field which has two shallow grooves in it at
differing levels giving a clue to the fields former use - but you will only detect this when the grass is
short. Somewhere beneath the grass are the 2nd and 3rd South Cerney Locks. At the south end of the field is
Northmoor Road (heading east to the A419). Across the road the canal bed is visible once again.
The canal swings across fields to the north of the river Churn, passing Boxwell Spring Lock
which has been completely transformed from a dirty ditch full of bushes and trees to a fully restored working
lock. It was originally built as an after-thought and only changes the level by 3 feet. It was hoped that the
level change would capture water from Boxwell Spring - unfortunately it did little to help water supplies. The
next lock is Humpback Lock (or Wildmoorway Upper Lock) which certainly didn't help water supplies as it is 11
feet deep! To help this problem a side pond was built which can still be found (carefully) in the undergrowth
to the west. Further south (just before the B4696 (Spine Road) is Wildmoorway Lower Lock which also has its own
side pond. The Dig Deep project began restoring this lock in 1994.
The canal continues - generally south - with the River Churn never far away. In fact, at one
point the river comes right to the towpath's edge. At Cerney Wick there is a neat roundhouse - still lived in -
beside a lock chamber which has been completely restored by the Dig Deep Project. The minor road to Cerney Wick
crosses just past the lock.
Another mile brings the canal into Latton and to the site of the former junction with the
North Wilts Branch of the Wilts & Berks Canal. As well as the junction there was a basin and a small
aqueduct over the Churn. A towpath bridge carried the towing horses over the entrance of the narrow North Wilts
Branch. Sadly, both the towpath bridge and aqueduct have gone. To south the Thames and Severn Canal continues,
still completely dry, heading towards the biggest hurdle in its history. This area may have changed a lot since
I was here in 1996 because the new A419 bypass now runs alongside the canal.
At the point where the new road crosses over, the canal was planned (by the Conservative
Minister of Transport) to be blocked by the building of the new dual-carriageway. Thankfully after years of
hard work - and the little matter of a change of government - the new Minister of Transport has ordered the
construction of a navigable culvert. In fact, at 100 yards in length it will be more of a tunnel than a
Cricklade Wharf and its wharf house are just 100 yards north of the River Thames Bridge at
the end of the high street in Cricklade. They were situated at the junction of the old A419 with the minor road
to Kempsford and the road into Cricklade high street. However, because of the building of the new road I am not
sure if this description still applies. The road into Cricklade (itself a one time A419) crosses the canal near
the old wharf. There used to be a lock and other canal buildings at the wharf but the only proof of the canal's
existence here now is the flat fronted warehouse standing among farm buildings. The minor road to Kempsford
runs roughly parallel to the canal for most of its journey eastwards into Kempsford. Some parts of this stretch
of the canal sometimes hold water though other parts have disappeared under ploughed fields. About a mile east
of Cricklade, standing among the fields, all alone in the "back of beyond", is an ivy-clad house named Eysey
Cottage. In the undergrowth in front of the cottage is Eysey Lock which still has its bottom gates intact and
because of this, the pound beyond is still in water.
About half way along the Kempsford road is the left turn to Marston Meysey village, just
past this junction is a footpath on the right which leads south to Marston Meysey roundhouse. My reference book
written in 1971 said the house was in a dilapidated state though it is now fully restored and lived in and has
had a large modern building added to it. Consequently it is now on private land and not easy to see. Between
Marston Meysey and Kempsford the canal bed is dry and in most places it is totally none existent. Farmers have
reclaimed the land and flattened the small embankment that the canal once rode along. At one point Oatlands
hump backed bridge has been left standing in the middle of a field doing nothing and going nowhere. At
Kempsford the canal passes a wharf with a wharf house similar to the ones at Cirencester and Cricklade where
the wharfinger's house and a warehouse were uniquely incorporated in a single building. Past the wharf a minor
road crosses the canal route and heads south east to the village church. I visited Kempsford in 1996 and
located the canal crossing, its bridge has long since gone and the canal has been completely filled in with
nicely cut grass stretching east and west marking the narrow route between side walls of gardens.
Out in the fields to the east are the Dudgrove pair of locks and at Inglesham is the final
lock chamber and the junction with the Upper Thames. At the junction is a picturesque group of buildings which
include the final roundhouse. The junction is fairly isolated and is best reached by walking along the River
Thames for about ½ a mile from Lechlade. By doing this you will come to a wooden footbridge over the river,
beyond this is a winding hole and the head of navigation for boats on the River Thames. At the winding hole the
small River Coln runs in on the north bank and the junction buildings are just beyond this. In among these
buildings it is possible to spot the top of the final roundhouse but hidden out of site among the buildings is
the lock and its hump backed bridge. Because the canal junction and lock are on private ground it is impossible
to view them properly. A canal walks book suggests you should cross the Thames then go through a gate and cross
a drawbridge over the River Coln and knock on a door to ask if you can take a look around. Well - its up to you
- but don't say I sent you!
The Thames & Severn Canal Company buildings are in Lechlade on the River Thames beside
Ha'penny Bridge. The buildings are now part of a small retail centre. I saw these buildings when I parked in
their car park. The only trouble is - at that time I did not know what they were!
Note: Since this page was written in 1997 a great deal of work has been
done (mostly by volunteers) in clearing the derelict canal and restoring parts of it. However, there is also a
strong campaign from local people who are against the re-opening of the canal.
