River Ryton
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.
While much of its route is rural, its course through Worksop is man made, a result of development and milling. It used to flow through Scrooby, where there was a mill, but was diverted northwards in the 1960s. It supplies water to the Chesterfield Canal through two feeders, and a number of the bridges which cross it are of interest architecturally, which has resulted in them becoming Listed structures.
The water quality of the river is moderate, as a considerable proportion of the total flow is supplied by the processed water from sewage treatment works. Despite this, there are significant populations of fish in the river, and it is used for organised angling.
The region through which the river flows is underlaid by an extensive water-bearing porous rock structure called the Magnesian Limestone aquifer, which is near the surface in the west and dips downwards to the east. Magnesian Limestone is so called because it contains quantities of the mineral Dolomite, which is rich in Magnesium. The Triassic Sherwood Sandstone aquifer is another porous rock layer which covers this to the east, and is the major geological component of the area. Further east, they are both covered by a layer of Mercia Mudstone. Where these aquifers reach the surface, they often supply water to the river system, but can also take water from it. This is affected by the extraction of groundwater, particularly for public water supply, and by fracturing of the aquifers as a result of subsidence caused by deep coal mining.
The Ryton draws its water from the Anston Brook, the Pudding Dyke, the Bondhay Dyke, and to a lesser extent the Broadbridge Dyke. Prior to the construction of the Chesterfield Canal in the 1770s, the flow of the Broadbridge Dyke was much greater, but water from its catchment area was diverted to form the reservoirs at Pebley and Harthill, which supply the canal. Overflow from the reservoirs reaches the Ryton by the Pudding Dyke, but the river also supplies water to the canal via the Brancliffe feeder and the Kilton feeder. The natural water sources are supplemented by the outflows from Dinnington and Anston Sewage Treatment Works into the Anston Brook, which together provide about 7 Ml/d (megalitres per day), while Kilton Treatment Works supplies about 12.8 Ml/d. At Manton, excess flow from the canal tops up the river, and water pumped from Manton Colliery formerly performed the same function. With the closure of the mine, a new borehole was constructed in 2004, and water is pumped from the Sherwood Sandstone aquifer into the river. The borehole is operated by Severn Trent Water.
In order to monitor flows on the river, the Environment Agency maintain gauging stations, one to the east of Worksop and a second to the east of Blyth at Craig y Nos. They also have one on Oldcotes dyke, just below Blyth Old Bridge. The catchment area above the Worksop gauging station is 29.7 square miles (77 km2) and the mean flow is 8.55 million gallons (38.88 Megalitres) per day. The catchment receives 25.8 inches (655 mm) of rainfall in an average year. Oldcoates Dyke contributes 12.92 million gallons (58.75 Ml) per day, and the flow at the Blyth gauging station amounts to 28.89 million gallons (131.3 Ml) per day, derived from a catchment area of 89 square miles (231 km2). This station has been operational since 1984. Previously, there was a gauging station a little further downstream at Serlby Park, but this was decommissioned in 1978, as the flow readings in the summer were not reliable. Data from the Blyth station is transmitted to the pumping station at West Stockwith, where it is used to control discharges from the River Idle into the River Trent.
Normal river levels at Worksop vary between 0.5 feet (0.15 m) and 0.92 feet (0.28 m), but when the weather is more extreme, can rise up to 3.43 feet (1.05 m). The highest level recorded at the gauging station was on 26 June 2007, when it reached 7.19 feet (2.19 m). At Blyth, the normal range is from 1.38 feet (0.42 m) to 2.53 feet (0.77 m), rising to 5.25 feet (1.60 m) in severe weather. The highest level recorded was on 8 November 2019, when the river level reached 7.62 feet (2.32 m).
The River Ryton starts to the east of Kiveton Park, next to the Chesterfield Canal, close to the 260-foot (79 m) contour. It is accompanied by the Sheffield to Lincoln Railway line which crosses it three times, before its flow is supplemented by Pudding Dyke, flowing northwards from Thorpe Salvin. It passes under the railway again, and under the freight line from Worksop to Doncaster Railport. At Lindrick Dale, Anston Brook, flowing in from beyond Anston to the west, joins on the left bank. Shortly afterwards, the Brancliffe feeder leaves the river, following an S-shaped course to supply water to the Chesterfield Canal near Turner Wood locks. A little further east, it crosses under the Sheffield to Lincoln Line again and through a three-arched aqueduct below the Canal, to pass through Shireoaks. It then loops around the village of Rhodesia, crossing under the Worksop to Nottingham railway line and the A57 Worksop bypass to arrive on the western edge of Worksop.
