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 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 west of Market Rasen, where it is joined by the Rase. North of there it flows through the market town of Brigg before draining into the Humber at South Ferriby. It drains a large 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 Foss Dyke, or Fossdyke, connects the River Trent at Torksey to Lincoln, the county town of Lincolnshire, and may be the oldest canal in England that is still in use. It is usually thought to have been built around AD 120 by the Romans, but there is no consensus among authors. It was refurbished in 1121, during the reign of King Henry I, and responsibility for its maintenance was transferred to the city of Lincoln by King James I. Improvements made in 1671 included a navigable sluice or lock at Torksey, and warehousing and wharves were built at Brayford Pool in the centre of Lincoln.
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 whose source is the confluence of the River Maun and River Meden near Markham Moor. The Idle flows north from its source through Retford and Bawtry before entering the River Trent at West Stockwith. Its main tributaries are the River Poulter and the River Ryton. The river is navigable to Bawtry, and there is a statutory right of navigation to Retford. Most of the land surrounding the river is a broad flood plain and the river is important for conservation, with Sites of Special Scientific Interest being designated along its course.
The River Lymn is a river in Lincolnshire, England. It rises in the Wolds on the eastern slope of Castcliffe Hill in Fulletby parish. It flows south-eastwards to the Lincolnshire Marsh, where it becomes known as the Steeping River on the boundary of Great Steeping parish. The main channel is supplemented by the Wainfleet Relief Channel as it passes Wainfleet All Saints, and the relief channel is joined by the old course of the Lymn. Once the two channels rejoin, there are three flood defence structures to protect the region from flooding by the North Sea.
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.
According to Whites 1856 Lincolnshire, Lawress Wapentake was one of the south-western divisions of the parts of Lindsey, in the Deanery and Archdeaconry of Stow, and consisting of the East Division and the West Division.
An internal drainage board (IDB) is a type of operating authority which is established in areas of special drainage need in England and Wales with permissive powers to undertake work to secure clean water drainage and water level management within drainage districts. The area of an IDB is not determined by county or metropolitan council boundaries, but by water catchment areas within a given region. IDBs are geographically concentrated in the Broads, Fens in East Anglia and Lincolnshire, Somerset Levels and Yorkshire.
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.
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 Foulness is a river in the East Riding of Yorkshire, England. Its name is derived from Old English fūle[n] ēa, meaning “dirty water”. Maintenance responsibilities for the river transferred from the Environment Agency to the Market Weighton Drainage Board on 1 October 2011. Market Weighton Drainage Board subsequently amalgamated with the Lower Ouse Internal Drainage Board on 1 April 2012 to create the Ouse and Humber Drainage Board. The river discharges into the Humber Estuary via Market Weighton Canal. Water levels within the river, its tributaries and the canal are managed and controlled by the Environment Agency. The river lies in an area known as the Humberhead Levels.
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.
The River Eau is a 15-mile-long (24 km) tributary of the River Trent that flows through Lincolnshire, England.
Witham Third District IDB is an English internal drainage board 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 north and east of the River Witham, between Lincoln and Dogdyke, which includes the valley of the River Bain to above Hemingby, and the valleys of Barlings Eau and most of its tributaries, to the north east of Lincoln.
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.
Welton Beck is a small local stream which originates from Old Man's Head Spring in the west of Welton civil parish and flows eastwards through Welton and Dunholme in the West Lindsey district of Lincolnshire for approximately 10 km (6.2 mi) to a confluence with Barlings Eau near Reasby, which goes on to join the River Witham. The beck is fed from groundwater springs of the Lincolnshire limestone aquifer, with clear freshwater and aquatic plant growth typical of calcareous conditions. The channel of the beck has been largely modified from its original state, having been widened, straightened, and its course significantly altered.
