South Forty-foot drain
Encyclopedia
The South Forty-Foot Drain is the main channel for the land-drainage of the Black Sluice Level in the Lincolnshire
Fens
. It lies in eastern England
between Guthram Gowt
and the Black Sluice pumping station on The Haven
, at Boston
. The Drain has its origins in the 1630s, when the first scheme to make the Fen land available for agriculture was carried out by the Earl of Lindsay, and has been steadily improved since then. Water drained from the land entered The Haven by gravity at certain states of the tide until 1946, when the Black Sluice pumping station was commissioned.
The Drain was navigable until 1971, when improvements to the pumping station led to the entrance lock being removed. It is currently being upgraded to navigable status by the Environment Agency
, as part of the Fens Waterways Link
, with a new entrance lock being completed in December 2008, giving access to the first 12 miles (19.3 km) of the drain, and the upgrading of the southern section, including a link to the River Glen
to allow navigation to Spalding
forming phase 2 of the project.
between the Parts of Holland
and the Parts of Kesteven, two of the three medieval subdivisions of Lincolnshire which functioned as county councils until their abolition in 1974. The first serious attempt to drain the area to the south west of Boston
, now known as the Black Sluice Area but formerly known as the Lindsay Level, was from 1635 to 1638, when the Earl of Lindsay
agreed with the Commissioners of Sewers for Lincolnshire to carry out drainage works which would make 36000 acres (145.7 km²) of land available for agricultural use. The Earl and his colleagues paid for the works, in return for land grants.
The cost of the work was £45,000, and involved the construction of a sluice near Boston, called Skirbeck Sluice, the construction of the first 8 miles (12.9 km) of the South Forty-Foot Drain, from Boston to Great Hale
, the construction of two drains from there to Guthram, which were called the Double Twelves, and the construction of the Clay Dyke Drain. The scheme was not popular with local landowners, who destroyed much of the work and burnt the Skirbeck Sluice. The Earl of Lindsay's contract with the Commissioners of Sewers was revoked by parliament, and it was another hundred years before the next attempt to drain the area.
In an attempt to drain Holland Fen, and prevent flooding from the River Witham
, an adventurer called Earl Fitzwilliam constructed a drain in 1720, which runs broadly parallel to the River Witham, and terminated at Lodewick's Gowt, a sluice which he constructed on the Witham close to the location of the present Grand Sluice. The drain was for many years called Earl Fitzwilliam's drain, but is now called the North Forty-Foot Drain. The scheme was not entirely successful.
, Ewerby
, Great Hale, Heckington
, Holland Fen, Howell
, Little Hale
and South Kyme. Much of the area to the south and west of Boston, some 91 square miles (235.7 km²), was inundated by the Great Flood of 1763, and against this background, the Black Sluice Drainage and Navigation Act 1765 was obtained which created the Black Sluice Commissioners, giving them power to raise taxes and authority to carry out drainage works. The scheme largely revived the Earl of Lindsay's original scheme. The initial design work was carried out by the civil engineer Langley Edwards, on loan from the Witham Commissioners. Some of the surveying was performed by John Landen, who was the steward of the estate of Earl Fitzwilliam at Peterborough, and a proficient amateur mathematician. The two men were jointly appointed Surveyors of the Works, acting as engineers for the scheme, while John Chapman and Richard Strattard were assistants. A new sluice
, called the Black Sluice, was built at Boston as a direct replacement for the Skirbeck Sluice, having three openings with a total width of 40 feet (12.2 m). The 8 miles (12,874.7 m) of the drain were scoured from Boston to Great Hale, beyond which the Main Drain was upgraded by cutting a new 14 miles (22.5 km) channel, effectively extending the South Forth-Foot Drain to Guthram, on the banks of the River Glen
. A total of 65 miles (104.6 km) of highland streams were improved by scouring and raising of the banks. The estimated cost of £16,000 was raised by issuing bonds, but the project overran, and another Act of Parliament was obtained in 1770 to authorise the raising of the drainage taxes, to cover the difference. By mid-1769, when Landen and Edwards left the project, because the work was largely complete, the scheme had cost £24,000. They were replaced by Edward Hare as Surveyor of Works, with Chapman and Strattard continuing as assistants. A historian called W. H. Wheeler, who chronicled the Lincolnshire fens, wrote that "the works were efficintly carried out and, being well-designed, entirely answered expectation."
On the River Witham
, the Grand Sluice was constructed and opened on 15 October 1766, and this prevented tidal water from entering the river, and hence flooding the Holland Fen. The Boston Harbour Commissioners were created by the Boston Port Act 1766, and they carried out improvement works to The Haven
, which resulted in lower water levels at the Black Sluice, and hence more efficient draining from the South Forty-Foot Drain. Water was pumped into the drain by a series of windmills driving scoop wheels. Maps of the area produced in 1783 by Edward Hare show 46 such mills, which provided drainage for 32000 acres (129.5 km²) of agricultural land. Extreme high tides in 1810 and again in 1820 resulted in widespread flooding, and further thought was given to improving the flood defences.
With the improvements to the River Witham, the final section of Earl Fitzwilliam's drain to Lodewick Gowt was filled in, and the channel was diverted to join the South Forty-Foot Drain. Renamed the North Forty-Foot Drain, it now supplies Cooks Lock and Holland Fen pumping stations.
to collect water draining from the higher ground to the west before it entered the fenlands, but an Act of Parliament to authorise its construction was defeated, and so in 1846 a report by Mr W Cubit which proposed improvements to the existing infrastructure was accepted by the Commissioners. A new Black Sluice, including a 20 feet (6.1 m) wide navigation lock, was constructed to the south of the original one, with the cill level 6 feet (1.8 m) lower, which enabled the gradient of the South Forty-Foot Drain to be increased to 3 inches per mile (5 cm/km). Many of the tributary drains were also improved. 1846 also marked the beginning of the use of steam engines for pumping. Ten years later, a map covering 18000 acres (72.8 km²) of the Black Sluice area showed nine steam-powered and eight wind-powered drainage engines in use.
The River Witham Outfall Improvement Act 1880 authorised further improvements to the mouth of the Witham, to which the Black Sluice Commissioners contributed £65,000. This work led to a further drop of 4 feet (1.2 m) in the low water level at the Black Sluice. Oil and paraffin
engines began to replace steam and wind engines from 1910, and by 1935 there were 15 such engines pumping water into the South Forty-Foot Drain. The passing of the Land Drainage Act 1930 resulted in the Commissioners being replaced by the Black Sluice Internal Drainage Board
, while responsibility for the rivers in the area passed to the Witham and Steeping Rivers Catchment Board. With war imminent, the Rivers Board took over the Black Sluice and the South Forty-Foot Drain in 1939, and although progress was interrupted by the Second World War, a £374,000 scheme to construct the Black Sluice pumping station and to widen 11 miles (17.7 km) of the drain from Boston to Donington Bridge was completed in 1946. The pumping station contained three 100 inches (2.5 m) pumps, each powered by a 900 hp 5-cylinder vertical diesel engine manufactured by Ruston
.
in 1990, and to the Environment Agency
in 1995.
Despite all the improvements, serious flooding occurred in 1999 when the bank of the drain was breached near Pinchbeck. Staff from the Environment Agency and the Black Sluice Internal Drainage Board successfully repaired the breach before properties were flooded, and a review of the flood defences was then carried out. The report recommended improvements to some of the banks, but funding for the work was not available, and so no work was done at the time.
to the west from South Holland
to the east. The boundary then continues southwards along the River Glen. North of Donington, the boundary between the borough of Boston
to the east and North Kesteven
to the west follows the line of the Drain. As the Drain crosses the line of the Midfen Dyke, just before the Nottingham to Boston railway
joins it at Great Hale pumping station, the boundary turns northwards, following its medieval course.
The main job of the Drain is to gather the waters pumped from the Kesteven Fens, the Holland Fens and the Weir Dyke, a soak dike
in Bourne North Fen, alongside the Bourne Eau
and River Glen
, northwards and eastwards to the Black Sluice at Boston, where they are discharged to the tidal waters of The Haven. The Weir Dyke takes its name from a weir
in the bank of the Bourne Eau at Tongue End, which was constructed by the Black Sluice Commissioners, to allow water from the Bourne Eau to overflow the bank when excess water could not flow into the River Glen in times of flood. The overfall weir became redundant when the Tongue End pumping station was constructed in 1966.
The South Forty-Foot Drain and the Black Sluice pumping station, together with most of the side channels which run into the drain are the responsibility of the Environment Agency. Management of the drainage ditches which drain the Fens are the responsibility of the Black Sluice Internal Drainage Board, who maintain 34 pumping stations and three gravity stations in the region. Of these, 21 are situated on the banks of the Drain, and pump directly into it, while one, the Black Hole Drove pumping station, is constructed over the channel, and acts as a boundary between the part of the Drain managed by the Environment Agency, and that managed by the Drainage Board.
promoted the idea that the Drain could again be made navigable as part of a larger scheme to improve leisure facilities. The local authorities which were part of the Fens Tourism consortium conducted a feasibility study, and this report was formally adopted as the Fens Waterways Link
by the Environment Agency in 2004, with the support of the local authorities, the East Anglian Waterways Association and the Inland Waterways Association
.
The scheme involves a total of 150 miles (241.4 km) of waterway, of which 50 miles (80.5 km) will be new cruiseway, while the rest will be existing waterways which will be upgraded or have their access improved. When completed, it will connect the Rivers Witham
, Glen, Welland
, Nene
and Great Ouse
, and is being heralded as the biggest waterway enhancement project in Europe by the Environment Agency
.
In 2007 they obtained funding for the link between Boston and Spalding
. Work on a new lock beside the Black Sluice pumping station at Boston
- to connect The Haven and the South Forty-Foot Drain - was formally started on 8 February 2008, and was completed in December 2008, with the official opening ceremony being held on 20 March 2009. The lock project formed phase 1 of the scheme, and the cost of £8.5 million was jointly funded by the European Regional Development Fund, the East Midlands Development Agency, and Lincolnshire County Council. The lock is designed to be used for a period either side of high tide, and so there is a rise from the Drain to the Haven. It has conventional mitre gates at one end, but uses rotating sector gates at the tidal end, each one weighing 12.1 tonnes.
The lock opens up nearly 12 miles (19.3 km) of waterway. As part of the upgrade, new 48-hour moorings have been constructed on The Haven, for boats about to enter the Drain, and on the South Forty-Foot Drain near the Black Sluice pumping station at Boston, at Swineshead Bridge and at Hubbert's Bridge.
The upper limit of navigation is initially Donington High Bridge, at which the Swaton Eau joins the South Forty-Foot Drain and provides a wider section where boats can be turned. Beyond the bridge, the drain is officially only suitable for canoes and kayaks.
However, eight narrow boats cruised on the waterway at Easter 2009, and although the channel is narrower and not as deep after Donington Bridge, all of the boats successfully reached Kingston's Bridge, some 3.7 miles (6 km) further on, where the outlets from Dowsby Fen and Gosberton pumping stations provide enough width to turn a 70 feet (21.3 m) boat. Further progress was blocked by scaffolding erected so that the bridge could be re-decked, rather than by lack of water.
The drain has been renamed as the Black Sluice Navigation by the Environment Agency. In order to use the navigation, an Environment Agency licence is required, and as there are no permanent moorings available on the drain, these are available for one day or seven days.
Water levels are maintained at a lower level during the winter months, when flows are high, and the Drain needs to be able to cope with higher volumes of rainfall, than during the summer months, when navigable levels are maintained. As on the neighbouring River Witham
, the switch between winter and summer levels is normally made at the beginning of April.
Phase 2 of the Fens Waterway project involves the link between Donington Bridge and Crowland and Cowbit Washes, which are located on the River Welland
near Spalding
. In order to make the financing of the phase more viable, it has been split into two halves, with phase 2a covering the section from Donington to Surfleet Seas End on the River Glen
, and phase 2b covering from there onwards. The initial technical assessment and obtaining of planning permission for phase 2, which involves widening of the South Forty-Foot Drain from Donington to a new road crossing under the A151, a new lock and a junction with the River Glen at Guthram Gowt was funded by the East Midlands Development Agency. This section will also involve changes at Black Hole Drove pumping station, which has been built across the drain and hence would prevent navigation. Major contracts for this phase were expected to be awarded in April 2009, but appraisal of the technical assessment revealed that more than one route needed to be considered before the best solution could be selected. While the obvious solution would be to connect the Glen and the drain where they are only a short distance apart, the Lincolnshire Waterways Partnership have also considered the creation of new channels up to 9.3 miles (15 km) long to form the link. In the meantime, the economic situation changed, so that sources of funding were not so freely available, and by the end of 2010, no clear dates had been set for the next construction phase.
at Oakham
and the Stamford Canal
at Stamford
, which had been discussed in 1785, were revived, as part of a larger plan for a 7 miles (11.3 km) link from Stamford to the River Nene at Peterborough, and a connection from near Market Deeping
, where the Stamford Canal rejoined the River Welland
, northwards to the South Forty-Foot Drain. A bill for this, together with one for a rival scheme to link Stamford to the Grand Junction Canal
, which also included a connection to the South Forty-Foot Drain, were put before Parliament in 1811, but neither met with any success. The idea was raised again in 1815 and 1828, but no further action was taken.

The Lincolnshire Fens are an area of low-lying land which have been subject to flooding and attempts to prevent it for centuries. In medieval times, the Midfen Dyke was built to drain the area, but by 1500, this was regarded less as a drain for the land than as a boundary markerBoundary marker

Reports on improvements to the system were produced in 1843 by the surveyor Mr W Lewin and in 1845 by Sir John Rennie. Rennie's scheme involved the provision of a catchwater drainCatchwater drain

Modern era
Paraffin and oil engines gave way to electrically powered pumping stations in the 1950s, with the Board constructing six electric and one diesel pumping station to improve drainage to an extra 11000 acres (44.5 km²) of land. In 1960, the decision was taken to further improve drainage of an area of 70000 acres (283.3 km²), as part of a £1.4 million scheme which included the addition of two extra pumps at the Black Sluice, replacement of existing pumps elsewhere, and the widening of 7 miles (11.3 km) of the South Forty-Foot Drain from Donington Bridge to Rippingale Running Dyke. Jurisdiction for the Drain and the sluice passed to the Lincolnshire River Board at this time. The work, which began in 1962 and was completed in 1968, proved successful in preventing flooding during severe wet weather in the winter of 1968/9. With three 900 hp and two 925 hp diesel engines, the upgraded pumping station can pump 800 thousand gallons per minute (60 m3/s).

in the bank of the Bourne Eau at Tongue End, which was constructed by the Black Sluice Commissioners, to allow water from the Bourne Eau to overflow the bank when excess water could not flow into the River Glen in times of flood. The overfall weir became redundant when the Tongue End pumping station was constructed in 1966.
The South Forty-Foot Drain and the Black Sluice pumping station, together with most of the side channels which run into the drain are the responsibility of the Environment Agency. Management of the drainage ditches which drain the Fens are the responsibility of the Black Sluice Internal Drainage Board, who maintain 34 pumping stations and three gravity stations in the region. Of these, 21 are situated on the banks of the Drain, and pump directly into it, while one, the Black Hole Drove pumping station, is constructed over the channel, and acts as a boundary between the part of the Drain managed by the Environment Agency, and that managed by the Drainage Board.
Navigation
Prior to 1971, the Drain had been navigable, but this privilege was removed at that time. It is unclear whether there was ever a right of navigation, or whether the Black Sluice Commissioners simply allowed it. The entrance lock was 72 by, and most trade was between Boston and Donnington Bridge, with pleasure boating not being allowed prior to 1962. The lock was closed and removed in 1971, with little protest being made. More recently, the East Anglian Waterways AssociationEast Anglian Waterways Association

promoted the idea that the Drain could again be made navigable as part of a larger scheme to improve leisure facilities. The local authorities which were part of the Fens Tourism consortium conducted a feasibility study, and this report was formally adopted as the Fens Waterways Link

The scheme involves a total of 150 miles (241.4 km) of waterway, of which 50 miles (80.5 km) will be new cruiseway, while the rest will be existing waterways which will be upgraded or have their access improved. When completed, it will connect the Rivers Witham

- to connect The Haven and the South Forty-Foot Drain - was formally started on 8 February 2008, and was completed in December 2008, with the official opening ceremony being held on 20 March 2009. The lock project formed phase 1 of the scheme, and the cost of £8.5 million was jointly funded by the European Regional Development Fund, the East Midlands Development Agency, and Lincolnshire County Council. The lock is designed to be used for a period either side of high tide, and so there is a rise from the Drain to the Haven. It has conventional mitre gates at one end, but uses rotating sector gates at the tidal end, each one weighing 12.1 tonnes.
The lock opens up nearly 12 miles (19.3 km) of waterway. As part of the upgrade, new 48-hour moorings have been constructed on The Haven, for boats about to enter the Drain, and on the South Forty-Foot Drain near the Black Sluice pumping station at Boston, at Swineshead Bridge and at Hubbert's Bridge.
The upper limit of navigation is initially Donington High Bridge, at which the Swaton Eau joins the South Forty-Foot Drain and provides a wider section where boats can be turned. Beyond the bridge, the drain is officially only suitable for canoes and kayaks.
However, eight narrow boats cruised on the waterway at Easter 2009, and although the channel is narrower and not as deep after Donington Bridge, all of the boats successfully reached Kingston's Bridge, some 3.7 miles (6 km) further on, where the outlets from Dowsby Fen and Gosberton pumping stations provide enough width to turn a 70 feet (21.3 m) boat. Further progress was blocked by scaffolding erected so that the bridge could be re-decked, rather than by lack of water.
The drain has been renamed as the Black Sluice Navigation by the Environment Agency. In order to use the navigation, an Environment Agency licence is required, and as there are no permanent moorings available on the drain, these are available for one day or seven days.
Water levels are maintained at a lower level during the winter months, when flows are high, and the Drain needs to be able to cope with higher volumes of rainfall, than during the summer months, when navigable levels are maintained. As on the neighbouring River Witham

, and phase 2b covering from there onwards. The initial technical assessment and obtaining of planning permission for phase 2, which involves widening of the South Forty-Foot Drain from Donington to a new road crossing under the A151, a new lock and a junction with the River Glen at Guthram Gowt was funded by the East Midlands Development Agency. This section will also involve changes at Black Hole Drove pumping station, which has been built across the drain and hence would prevent navigation. Major contracts for this phase were expected to be awarded in April 2009, but appraisal of the technical assessment revealed that more than one route needed to be considered before the best solution could be selected. While the obvious solution would be to connect the Glen and the drain where they are only a short distance apart, the Lincolnshire Waterways Partnership have also considered the creation of new channels up to 9.3 miles (15 km) long to form the link. In the meantime, the economic situation changed, so that sources of funding were not so freely available, and by the end of 2010, no clear dates had been set for the next construction phase.
