Dartmoor Preservation Association Landholding at River Swincombe

Land adjoining the newtakes of Tor Royal and Fox Tor and common land around Fox Tor Mire and the River Swincombe and Strane were acquired in the 1930’s by South West Water from the Duchy in preparation for the building of a proposed Swincombe reservoir. The shape of the land parcel was predicated on the outline of the proposed reservoir. Fast forward to December 1970, the House of Commons heard a bill to consider the proposal to build a dam across the Swincombe valley. History shows against all the odds the bid was rejected.

The plan was to create a 754-acre reservoir with a large dam crossing the valley about 250 yards downstream from Stream Hill Ford.  The reservoir itself would have been triangular shaped with each side stretching for nearly two miles. Water was to be taken from the Strane and Swincombe as well as from the West Dart, Cowsic and Walkham rivers, via the concreted and widened Devonport and Prison Leats. 

In July 1975, South West Water confirmed their future sources of water supply for the south west and finally took Swincombe off the list having previously added it “back on the list” in November 1974. The area was saved for a second time. In 1985, the Dartmoor Preservation Association were able to acquire 50 acres of land around the Swincombe from South West Water with funds from a bequest specifically for land purchase made by the late Miss M. Loveday Trahair. This land is located where the proposed dam would have been built. This post covers features which are contained within (or adjacent to) this 50 acres of land. Source of information for this post has been obtained from DPA website, campaigner Kate website, Dave Brewer, Dartmoor Boundary Markers book (second edition), Dartmoor HER and Follow the Leat book by John Robins.

The land acquired by the DPA includes the confluence of the Strane and Swincombe rivers and downstream as far as the Fox Tor farm newtake wall. It also includes just under 9 acres of land within the Tor Royal newtake. In 1987, a series of ten boundstones were erected by the DPA to mark the boundary of this land. The boundary is also marked by three concrete posts. The map shows the DPA land, which within its borders includes 4 locations of tinners’ buildings, a building called Sam Parr’s House, the “Boiler” plus a couple of weirs, a sluice and an overspill associated with the 19th century Wheal Emma Leat. All the features shown in the map are covered in this post.
Trehair 1
The plaque dedicated to Miss M. Loveday Trahair is located just below the “Boiler” on a large boulder in the Swincombe. The plaque is located at SX62478 71145.
Trehair 2
Trehair 3
Near the Loveday Trahair plaque is a large boulder with a shallow rock basin on its top.
Boiler 1
The “Boiler” is a location on the Swincombe where large boulders fill the river bed and provide large stepping stones. It was Eric Hemery who referred to it as “The Boiler” when flood waters foam between the boulders.
Boiler 2
More pictures of the “Boiler”. The area is also known to some as “Boiling Cauldron” and is named as such in an article by campaigner Kate found here: Swincombe—saved for the second time
DPA 1.1
The DPA boundstones around the Swincombe are similar to those found at Sharpitor (where the DPA acquired 32 acres of land in 1984). The picture shows Boundstone (1), as marked on the sketch map and is on the north east boundary of the land acquired.
DPA 1.2
Boundstone (1) with the Swincombe and the Fox Tor farm newtake wall and the slopes of Ter Hill in the background.
DPA 1.3
Boundstone (1) is located at SX62585 71562.
DPA 2.1
Boundstone (2). The boundstones are machine-finished slabs having an arched top.
DPA 2.2
Close up of Boundstone (2) which is located at SX62502 71489.
DPA 2.3
Boundstone (2) is located close to a gate in the fenceline.
DPA 3.1
Boundstone (3) looking down the Swincombe valley.
DPA 3.2
Boundstone (3) is located at SX62477 71393.
DPA 3.3
Boundstone (3), like each of the boundstones is approx 1m tall.
DPA 4.1
Boundstone (4) is probably the most difficult to find due to the tall grass and isn’t prominent until the explorer gets quite close to it.
DPA 4.2
Boundstone (4) looking south showing the line of Wheal Emma Leat above the Swincombe.
DPA 4.3
Boundstone (4) is located at SX62452 71285.
Between Boundstone (4) and Boundstone (5) are a number of large boulders forming a small outcrop, which the author believes is un-named. Perhaps a suitable name is Swincombe Tor or North Swincombe Rocks (note: there is already a Higher Swincombe Rocks further down the valley). These boulders can be found at SX62421 71240.
DPA 5.1
Boundstone (5) is relatively easy to locate where the grass is relatively short
DPA 5.2
Boundstone (5) looking south west towards the Wheal Emma Leat take off point from the Swincombe.
DPA 5.3
Boundstone (5) is located at SX62384 71196.
DPA 6.1
Boundstone (6) is located close to the old hunting gate, now called the Geoffrey Sayer gate.
DPA 6.2
Boundstone (6) as with all the other boundstones has the letters “DPA” incised in a slightly sunken oval panel. All stones are now quite weathered and the letters are not that clear on all of them.
DPA 6.3
Boundstone (6) is located at SX62287 71131
Sayer 2
The old hunting gate now known as the Geoffrey Sayer gate. If looking for the 6 boundstones (1-6) to the north of the Swincombe, the explorer should use this gate, then the gate in the fenceline shown in the photograph. Boundstone (6) can be seen from the north side of the gate.
Sayer 1
Geoffrey Sayer passed away on 17 February, 2013 aged 82. He was the son of Guy Sayer (later Vice-Admiral Sir Guy) and Sylvia Sayer the well known campaigner and champion of Dartmoor. A delightful article about Geoffrey Sayer can be found here : https://campaignerkate.wordpress.com/2013/03/16/geoff-sayer-no-nonsense-enthusiast/
As well as the 10 boundstones marking the 50 acre boundary of the DPA landholding, there are (or at least once were) three concrete posts. Post (P1 on sketch map) can be found at SX62197 71066.
Concrete post P1 looking east towards Geoffrey Sayer gate.
It is surprising that the DPA didn’t add to the boundstones and kept a concrete post as a boundary marker.
DPA Boundary
Concrete posts P1 and P2 could not be found by the author. If they are still in position they would lie somewhere on the line indicated in the photograph. The area is quite marshy and tussocky.
DPA 7.1
Boundstone (7) can be found near the River Swincombe. Next to the boundstone is concrete post, which one assumes was the original boundary marker before the DPA boundstone was erected.
DPA 7.2
Boundstone (7) has a lot of lichen on it. The photograph shows the boundstone with Whiteworks in the distance to the north west.
DPA 7.3
Close up of boundstone (7) which can be found at SX62336 70785.
DPA 8.1
Boundstone (8) can be found near a small footpath between the Wheal Emma Leat take off point and Fox Tor farm
DPA 8.2
Boundstone (8) can be found at SX62365 70983.
DPA 8.3
The ‘DPA’ incised letters are quite clear on boundstone (8).
Between boundstones (8) and (9) there is a great view across the Swincombe with views of Sam Parr’s House and the small outcrop (which lies between boundstones (4) and (5)).
DPA 9.1
Boundstone (9) is best approached from the south and cannot be seen from the Wheal Emma Leat.
DPA 9.2
Boundstone (9) with superb views down the Swincombe valley. The grass is quite long here and the ground quite tussocky.
DPA 9.3
Boundstone (9) is located at SX62597 71129.
Clapper 1
Just to the east of the Fox Tor farm newtake wall there is a fabulous four granite slabbed clapper straddling the now dry Wheal Emma Leat.
Clapper 2
The clapper is located at SX62787 71321. From this point, the wall (west side) must be followed uphill to find boundstone (10).
DPA 10.1
Boundstone (10) is located next to the Fox Tor farm newtake wall.
DPA 10.2
Boundstone (10) can be found at SX62803 71289.
DPA 10.3
Being quite sheltered the ‘DPA’ incised letters on boundstone (10) haven’t weathered as much as on the other boundstones in the area.
WETO map
Within the DPA landholding lies the take off point for the Wheal Emma Leat. The leat channel from this area was cut in 1859 to supplement the volume of water taken from the river Mardle to supply the water wheels at Wheal Emma copper mine which is located near Buckfastleigh. The whole leat is just over 9 miles long. Primarily water was taken from the River Swincombe but 19th century maps show this was supplemented by water taken from the Strane river from the west as can be seen from the map.
Just downstream from the two weirs, there are two walls set into opposite banks of the river, which suggests there might have been a footbridge here at one point. However, with reference to “Follow the Leat” by John Robins (page 36), he mentions (and shows a photograph) a sluice gate, which when in position, would have raised the water level to supplement the water into the Wheal Emma Leat. This structure can be found at approx. SX62268 70992
WETO map 2
Using the 19th century map of the area, the author speculates how the system may have worked. Firstly, the Strane river was redirected by a weir changing the direction of the river straightening it into a east/west direction. A second weir across the Swincombe would direct the water into the Wheal Emma Leat. The sluice gate (most probably) have been used to take account of weir water leakages (?) and the the water would have been raised and directed back toward the leat. The 19th century map, does suggest a secondary water inlet point to the east of the weir. The author does have some doubt about this theory and would welcome any comments. There is also a small spillway a short distance from the start of the Wheal Emma Leat start point.
The weir on the Strane river has all but disappeared. That said by looking at the old 19th century map, it can be deduced it was located where the river now bends 90 degrees from a west – east direction to a north – south direction. The man made banks hereabouts and the marshy area as shown in the picture indicate the probable water course that would have been taken to supplement the water feed from the Swincombe.
The Wheal Emma leat take off point from the Swincombe (and Strane) is a little more obvious as there are 5 granite posts located here. John Robins in his book “Follow the Leat” suggests that two of the five slabs were in fact part of an old footbridge with the remaining three being the old weir.
The five granite slabs of the Swincombe weir can be located at SX62245 70966.

The spillway can be found at SX62264 70979.
Tinners 1
Within the 50 acre DPA landholding at Swincombe lies a numbers of tinners’ buildings. They are marked 1-4 and as Sam Parr’s house on the sketch map found at the start of this post. Tinners’ building 1 is described in the Dartmoor HER as being “small and indistinct but well-preserved. It is recorded as measuring approximately 3.0 by 2.0 metres internally and has walls 0.5 metres wide. There is an entrance gap in the south-east wall. Walls survive to a maximum height of about 1.0 metres in the north corner”. This building may be 16th / 17th century. It can be located at SX62196 71002.
Shot 1
A short distance from Tinners’ Building 1 lies some large boulders with shot-holes caused by blasting with gunpowder. Most likely from the 19th century.
Shot 2
Close up of shot hole.
Shot 3
The group of boulders with the shot-holes (grooves) can be found at SX62194 71012.
Tinners 2.1
Tinners’ Building 2 (ref sketch map at start of this post) was noted by Haynes and described as a “Ruined building probable dwelling north with enclosure to west, possible fireplace to east. The only possible location the author has found was at SX62295 71101 with this section of walling.
Tinners 2.2
Location of Tinners’ Building 2 looking towards the ‘Boiler”
Tinners 3 - plan
The third location of tinners’ building(s) is marked as 3 on the map. In actual fact, this are is more than just one building in this location as indicated by the simple sketch plan above.
Tinners 3.1
View of the Tinners Building 3 as viewed from the east. The Swincombe and Wheal Emma leat can also been seen in this photograph
Tinners 3.2
This tinners building is described on the Dartmoor HER as being a “substantially built rectangular structure measuring 5.7 metres north to south by 2.5 metres with an entrance in the centre of the west side. A crudely constructed cross wall, probably not an original feature, now sub-divides this building”. The centre of this building is located at SX62378 71136.
Tinners 3.3
Adjacent to the main Tinners Building 3 is an outbuilding recorded as measuring “2.8 metres north to south by 2.0 metres internally with an entrance in the north-east corner”. The photograph is taken from the north so the entrance is ‘bottom left’ from this view. This outbuilding is located at SX62373 71130.
Tinners 3.4
Also adjacent to the tinners’ building is an enclosure, a gatepost, a probable wheel pit and associated tailrace.
Tinners 3.5
Panning back from the previous photograph, the features of the complex can be seen in relation to the outbuilding in the foreground.
Tinners 3.6
Gatepost at SX62376 71132.
Tinners 3.7
The enclosure. The middle was measured at SX62383 71128.
Tinners 3.8
Next to the west wall of the main building is a rectangular hollow described in the Dartmoor HER as being “5.0 metres north to south by 2.0 metres, probably the site of a wheelpit but now allowing access to the building”.
Tinners 3.9
To the south of the probable wheelpit lies the (probable) tailrace and also a possible buddle. The buddle was measured at SX62383 71122.
Tinners 3.10
Above (to the north) of the Tinners building 3 is a leat only 1.0 metre wide and 0.3 metres deep which supplied a small irregular reservoir which was recorded at SX62373 71142.
Tinners 3.11
Final view of Tinners building 3 complex viewed from on top of the bank looking south west.
Tinners 4.1
Tinners’ building 4 can be found to the east of the Tinners building 3. This is described in the Dartmoor HER as being “a very ruinous building measuring 6.1 metres east to west by 4.3 metres with an entrance positioned centrally in the south side”. It can be located at SX62415 71148.
Tinners 4.2
The relative locations of the two Tinners’ buildings, looking west.
Tinners 4.3
The remains of a fireplace in the east end of Tinners building 4.
Tinners 4.4
A platform 9.4 metres east to west by 1.4 metres and 0.3 metres deep lies 3 metres to the south of Tinners’ building 4 and would appear to be a silted wheelpit. Ref: Dartmoor HER.
Sam Parr 1
Sam Parr’s house and outbuilding. The 1841 census return indicated the Parr family were living in this converted tinner’s hut by which time had acquired the name of Stream Cottage. Source: Legendary Dartmoor. The Parr family had moved in circa 1840. Dartefacts record the main building at SX62479 71187.
Sam Parr 2
The outbuilding measures 2.4 metres north to south by 1.5 metres with an entrance in the north-east corner. It is located at SX62472 71172.
Sam Parr 3
In the south east corner of Sam Parr’s house is a large inscription on one of the granite blocks.
Sam Parr 4
Sam Parr’s ‘Keep Safe/ Cache’ or ‘Candle Niche’.
Sam Parrs 5
The ‘HC 1753’ inscription enhanced with a mud makeover. The cross bar of the “H” doesn’t look complete.
Sam Parrs 6
View of Sam Parr’s house looking from the north towards the Swincombe. The line of Wheal Emma leat can be seen on the opposite bank.
Sam Parrs 7
The Dartmoor HER is described at as a “building measuring 6.2 metres south-west to north-east by 3.5 metres with an entrance placed centrally in the south-east side. A recess in the northern corner probably marks the site of the chimney”.

    As always, a fabulous piece of field work. I have walked in this area but don’t ever recall seeing the DPA stones. This is a great inspiration to get me out there again. Thanks for taking the time to document it so carefully and to share it.
