The River Witham is a river almost entirely in the county of Lincolnshire in the east of England. It rises south of Grantham close to South Witham at SK8818, passes through the centre of Grantham, passes Lincoln at SK9771 and at Boston, TF3244, flows into The Haven, a tidal arm of The Wash, near RSPB Frampton Marsh. The name "Witham" seems to be extremely old and of unknown origin. Archaeological and documentary evidence shows the importance of the Witham as a navigable river from the Iron Age onwards. From Roman times it was navigable to Lincoln, from where the Fossdyke was constructed to link it to the River Trent. The mouth of the river moved in 1014 following severe flooding, and Boston became important as a port.
The River Welland is a lowland river in the east of England, some 65 miles (105 km) long. It drains part of the Midlands eastwards to The Wash. The river rises in the Hothorpe Hills, at Sibbertoft in Northamptonshire, then flows generally northeast to Market Harborough, Stamford and Spalding, to reach The Wash near Fosdyke. It is a major waterway across the part of the Fens called South Holland, and is one of the Fenland rivers which were laid out with washlands. There are two channels between widely spaced embankments with the intention that flood waters would have space in which to spread while the tide in the estuary prevented free egress. However, after the floods of 1947, new works such as the Coronation Channel were constructed to control flooding in Spalding and the washes are no longer used solely as pasture, but may be used for arable farming.
The River Ancholme is a river in Lincolnshire, England, and a tributary of the Humber. It rises at Ancholme Head, a spring just north of the village of Ingham and immediately west of the Roman Road, Ermine Street. It flows east and then north to Bishopbridge, where it is joined by the Rase. North of Bishopbridge it flows through the market town of Brigg before draining into the Humber at South Ferriby. It drains a significant part of northern Lincolnshire between the Trent and the North Sea.
The River Wissey is a river in Norfolk, eastern England. It rises near Bradenham, and flows for nearly 31 miles (50 km) to join the River Great Ouse at Fordham. The lower 11.2 miles (18.0 km) are navigable. The upper reaches are notable for a number of buildings of historic interest, which are close to the banks. The river passes through the parkland of the Arts and Crafts Pickenham Hall, and further downstream, flows through the Army's Stanford Training Area (STANTA), which was created in 1942 by evacuating six villages. The water provided power for at least two mills, at Hilborough and Northwold. At Whittington, the river becomes navigable, and is surrounded by fenland. A number of pumping stations pump water from drainage ditches into the higher river channel.
The River Glen is a river in Lincolnshire, England with a short stretch passing through Rutland near Essendine.
The River Rother flows for 35 miles (56 km) through the English counties of East Sussex and Kent. Its source is near Rotherfield in East Sussex, and its mouth is on Rye Bay, part of the English Channel. Prior to 1287, its mouth was further to the east at New Romney, but it changed its course after a great storm blocked its exit to the sea. It was known as the Limen until the sixteenth century. For the final 14 miles (23 km), the river bed is below the high tide level, and Scots Float sluice is used to control levels. It prevents salt water entering the river system at high tides, and retains water in the river during the summer months to ensure the health of the surrounding marsh habitat. Below the sluice, the river is tidal for 3.7 miles (6.0 km).
The River Idle is a river in Nottinghamshire, England. Its source is the confluence of the River Maun and River Meden, near Markham Moor. From there, it flows north through Retford and Bawtry before entering the River Trent at Stockwith near Misterton. The county boundary with South Yorkshire follows the river for a short distance near Bawtry, and the border with Lincolnshire does the same at Idle Stop. Originally, it flowed northwards from Idle Stop to meet the River Don on Hatfield Chase, but was diverted eastwards by drainage engineers in 1628.
The River Ryton is a tributary of the River Idle. It rises close to the Chesterfield Canal near Kiveton Park, and is joined by a series of tributaries near Lindrick Common in the Metropolitan Borough of Rotherham, South Yorkshire, England. Most of its course is in Nottinghamshire, flowing through the town of Worksop. It meanders northwards to join the River Idle near the town of Bawtry on the South Yorkshire-Nottinghamshire border.
The River Nar is a river in England, a tributary of the River Great Ouse. It rises at Mileham near Litcham in Norfolk and flows 15 miles west through Castle Acre and Narborough, joining the Ouse at King's Lynn. It has had a variety of alternative names, such as the Setch, the Sandringham, and Lynn Flu, though these are rarely, if ever, used today. In 2011 the Nar was recognised by the Environment Agency as one of the top ten most improved rivers in England and Wales.
The Louth Navigation was a canalisation of the River Lud. It ran for 11 miles (18 km) from Louth in Lincolnshire, England, to Tetney Haven, at the mouth of the Humber. It was authorised by Act of Parliament in 1763 and completed in 1770, under the supervision of the engineer John Grundy Jr. and then by James Hogard. Eight locks were required to overcome the difference in altitude, six of which were constructed with sides consisting of four elliptical bays.
The South Forty-Foot Drain, also known as the Black Sluice Navigation, 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 Lindsey, 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.
Bourne Eau is a short river which rises from an artesian spring in the town of Bourne in Lincolnshire, England, and flows in an easterly direction to join the River Glen at Tongue End. Within the town, it once powered three water mills, one of which is now a heritage centre. At Eastgate, it becomes much wider as it was navigable in the 18th and 19th centuries, and this was the location of the terminal basin. Below the town it is an embanked river, as its normal level is higher than that of the surrounding Fens. Navigation ceased in the 1860s and the river now forms an important part of the drainage system that enables the surrounding fen land to be used for agriculture.
The Witham Navigable Drains are located in Lincolnshire, England, and are part of a much larger drainage system managed by the Witham Fourth District Internal Drainage Board. The Witham Fourth District comprises the East Fen and West Fen, to the north of Boston, which together cover an area of 97 square miles (250 km2). In total there are over 438 miles (705 km) of drainage ditches, of which under 60 miles (97 km) are navigable. Navigation is normally only possible in the summer months, as the drains are maintained at a lower level in winter, and are subject to sudden changes in level as a result of their primary drainage function, which can leave boats stranded. Access to the drains is from the River Witham at Anton's Gowt Lock.
Pode Hole is a small village 2 miles (3.2 km) to the west of the centre of Spalding, Lincolnshire, England. The village lies at the confluence of several drainage channels, where two pumping stations discharge water into Vernatt's Drain from land in Deeping Fen to the South and West. Water from Pinchbeck South Fen to the North is also lifted into Vernatt's Drain. The village arose to service the pumping stations.
Witham First District IDB is an English internal drainage board which was set up under the terms of the Land Drainage Act 1930. The Board inherited the responsibilities of the Witham General Drainage Commissioners, who were first constituted by an Act of Parliament of 1762. They manage the land drainage of an area to the west of the River Witham, between Lincoln and Dogdyke, which includes the valley of the River Slea to above Sleaford.
The River Torne is a river in the north of England, which flows through the counties of South Yorkshire and North Lincolnshire. It rises at the Upper Lake at Sandbeck Hall, in Maltby in South Yorkshire, and empties into the River Trent at Keadby pumping station. Much of the channel is engineered, as it plays a significant role in the drainage of Hatfield Chase, which it crosses.
South Holland IDB is an English internal drainage board set up under the terms of the Land Drainage Act 1930. It has responsibility for the land drainage of 148.43 square miles (384.4 km2) of low-lying land in South Lincolnshire. It is unusual as its catchment area is the same as the area of the drainage district, and so it does not have to deal with water flowing into the area from surrounding higher ground. No major rivers flow through the area, although the district is bounded by the River Welland to the west and the River Nene to the east.
The Beverley and Barmston Drain is the main feature of a land drainage scheme authorised in 1798 to the west of the River Hull in the East Riding of Yorkshire, England. The area consisted of salt marshes to the south and carrs to the north, fed with water from the higher wolds which lay to the north, and from inundation by tidal water passing up the river from the Humber. Some attempts to reduce the flooding by building embankments had been made by the fourteenth century, and windpumps appeared in the seventeenth century. The Holderness Drainage scheme, which protected the area to the east of the river, was completed in 1772, and attention was then given to resolving flooding of the carrs.
The River Till is a river in the county of Lincolnshire in England and is ultimately a tributary of the River Witham. Its upper reaches drain the land east of Gainsborough. The middle section is embanked, as the water level is higher than that of the surrounding land, and pumping stations pump water from low level drainage ditches into the river. Its lower reaches from the hamlet of Odder near Saxilby into the city of Lincoln were canalised, possibly as early as Roman times, as part of the Foss Dyke.
The Upper Witham IDB is an English Internal Drainage Board responsible for land drainage and the management of flood risk for an area to the west of the Lincolnshire city of Lincoln, broadly following the valleys of the upper River Witham, the River Till and the course of the Fossdyke Navigation.
