This is a list of tributaries of the River Tees from its source at Teeshead to its mouth at Middlesbrough. [1]
The following waterways empty into the reservoir.
High Force is a waterfall on the River Tees, near Middleton-in-Teesdale, Teesdale, England. The waterfall is within the North Pennines Area of Outstanding Natural Beauty (AONB) and the European Geopark. The waterfall is part of the historic county boundary between the North Riding of Yorkshire on the south bank, and County Durham on the north bank.
Pen-y-ghent or Penyghent is a fell in the Yorkshire Dales, England. It is the lowest of Yorkshire's Three Peaks at 2,277 feet (694 m); the other two being Ingleborough and Whernside. It lies 1.9 miles (3 km) east of Horton in Ribblesdale. It has a number of interesting geological features, such as Hunt Pot, and further down, Hull Pot. The waters that flow in have created an extensive cave system which rises at Brants Gill head.
A body of water or waterbody is any significant accumulation of water on the surface of Earth or another planet. The term most often refers to oceans, seas, and lakes, but it includes smaller pools of water such as ponds, wetlands, or more rarely, puddles. A body of water does not have to be still or contained; rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water.
The River Wyre in Lancashire, England, flows into the Irish Sea at Fleetwood. It is 28 miles (45 km) long and has a sheltered estuary which penetrates deep into the Fylde peninsula.
The Ease Gill Cave System is the longest, and most complex cave system in Britain as of 2011, with around 41 miles (66 km) of passages, including connections only passable by cave diving. It spans the valley between Leck Fell and Casterton Fell. The water resurges into Leck Beck.
Langbaurgh was a liberty or wapentake of the North Riding of Yorkshire. It covered an area of the shire's north-eastern tip. The wapentake took its name from Langbaurgh hamlet, in present-day Great Ayton parish.
Liddel Water is a river running through southern Scotland and northern England, for much of its course forming the border between the two countries, and was formerly one of the boundaries of the Debatable Lands.
Skirden Beck is a minor river in Lancashire, England. It is approximately 4.3 miles (6.85 km) long and has a catchment area of 18.87 square miles (48.882 km2).
Leck Fell is a Site of Special Scientific Interest in Lancashire, England. An area of typically heavily grazed open moorland of rough grass and remnant patches of heather with little or no tree cover, it is characterised by the virtual absence of surface drainage and an extensive subterranean drainage network resulting in cave systems and numerous sinkholes. It surrounds the high point of Gragareth 627 metres (2,057 ft) between Leck Beck and Kingsdale.
The River Greta is a river in County Durham, England. It is a tributary of the River Tees and flows through the northern part of the old North Riding of Yorkshire. The name "Greta" derives from the Old Norse "Griótá", meaning "stony stream".
The River Lune is a river in County Durham, England.
Newlands Beck is a minor river of Cumbria in England.
The Gaunless is a tributary river of the Wear in County Durham, England. Its name is Old Norse, meaning "useless". The Gaunless Viaduct, built in 1825, was the tallest viaduct on the South Durham & Lancashire Union Railway.
The Eller Beck is a small river in North Yorkshire, England, that flows through the town of Skipton and is a tributary of the River Aire. Its channel was heavily modified to supply water to mills in the 18th and 19th centuries, and although all the mills have closed, the water now supplies power to the National Grid, generated by a turbine at High Corn Mill. The beck flows through several underground culverts in Skipton that contribute to the flood risk. To alleviate flooding in Skipton town centre, a scheme involving two flood water storage reservoirs was designed and eventually completed in 2017.
The Three Counties System is a set of inter-connected limestone solutional cave systems spanning the borders of Cumbria, Lancashire and North Yorkshire in the north of England. The possibility of connecting a number of discrete cave systems in the area to create a single super-system that spans the county borders was first proposed by Dave Brook in 1968, and it was achieved in 2011. The system is currently over 86 kilometres (53 mi) long, making it the longest in the UK and the thirtieth longest in the world, and there continues to be scope for considerably extending the system.
The White Rose Pothole Club (WRPC) are a Caving Club founded in May 1954 and based in the Yorkshire Dales.
