The River Tees is in northern England. It rises on the eastern slope of Cross Fell in the North Pennines, and flows eastwards for 85 miles (137 km) to reach the North Sea between Hartlepool and Redcar near Middlesbrough.

Geography

It drains an area of 710 square miles (1834 square km) and has a number of tributaries including the River Greta, River Lune, River Balder, River Leven and River Skerne. Before the reorganisation of the historic English counties, the river formed the boundary between County Durham and Yorkshire. In its lower reaches it now forms the boundary between the ceremonial counties of County Durham and North Yorkshire, while in the highest part of its course it forms the boundary between the historic counties of Westmorland and Durham. The head of the valley, whose upper portion is known as Teesdale, has a desolate grandeur, surrounded by moorland and hills, some exceeding 2500 feet (762 m). This area is part of the North Pennine Area of Outstanding Natural Beauty.

The source of the river at Teeshead just below Cross Fell lies at an elevation of approximately 2,401 feet (732 m). It flows east-north-east through an area of Shake Holes through carboniferous limestone. Below Viewing Hill, it turns south to the Cow Green Reservoir constructed to store water to be released in dry conditions to support industrial need for water on Teesside.

Emerging from the reservoir at Cauldron Snout the river traverses a series of hard black basalt rocks, and dolerite that intrudes through the softer limestone, in a succession of falls or rapids. From this point downstream the Tees forms the boundary between the traditional counties of Durham and Yorkshire almost without a break, although since 1974 much of it lies wholly in Durham. The dale widens below Cauldron Snout, and trees appear, contrasting with the broken rocks where the water descends over High Force. After a short turn northwards, the river continues to meander south easterly. Close to where the B6277 road begins to runs parallel to the river is the 30 metres (98 ft) High Force waterfall. About 1.5 miles (2.4 km) downstream is the smaller Low Force waterfall.

The scenery becomes gentler and more picturesque as the river descends past Middleton-in-Teesdale (Durham). This locality has lead and ironstone resources. Just to the east of Middleton-in-Teesdale, the River Lune joins the Tees. After passing the village of Romaldkirk to the west, the river is joined by the River Balder at Cotherstone. The ancient town of Barnard Castle, Egglestone Abbey, and Rokeby Park, well known through Sir Walter Scott's poem, are all passed. At Rokeby the Tees is joined by the River Greta. From the area near Eggleston, the river is crossing over millstone grit. From here the valley begins to open out, and traverses the rich plain east and south of Darlington in large meandering curves.

The course of the valley down to here has been generally east-south-east, but it now turns north-east near the village of Whorlton. Passing Ovington and Winston it runs parallel to the A67 south-east past Gainford and Piercebridge to Darlington, passing under the A1 and A66. The section from Piercebridge to Hurworth is flowing over magnesian limestone. It is at Croft-on-Tees that the River Skerne joins the Tees. The river now flows south past Croft-on-Tees before swinging northwards past Hurworth-on-Tees. A series of large meanders takes the course past Neasham, Low Dinsdale and Sockburn to Middleton St George. In the lower reaches of the river valley the water is flowing over bunter sandstone and pebble beds.

Just past Yarm, the River Leven joins the Tees, before passing the settlements of Eaglescliffe, Ingleby Barwick and Thornaby-on-Tees. Now nearing the sea, the Tees becomes an important commercial waterway, with the ports of Stockton-on-Tees and Middlesbrough on its banks. It passes through the Tees Barrage between these ports, turning tidal downstream from the barrage.

Teesport is built on reclaimed land on the south side of the Tees estuary below Middlesbrough.

Seal Sands

Before the heavy industrialisation of the Tees, the flats at Seal Sands in the estuary were home to Common Seals. For around 100 years this species was absent from the estuary but have now returned and can be seen on the flats at Seal Sands. The Seal Sands area is now designated as the Teesmouth National Nature Reserve.

Alterations

The River Tees (Portrack Cut) passing through the Green-Blue Heart of the Tees Corridor between Middlesbrough and Stockton District.

In the early 19th century the river was straightened, thus saving money and time in navigation. Between Stockton-on-Tees and Middlesbrough, the river previously meandered first south and then north of its current channel. Two "cuts", known as the Mandale Cut and the Portrack Cut were made to straighten its course. Before these cuts were made, the journey by sailing barge from Thornaby to Middlesbrough, allowing for tides and other factors, could take as long as the journey from the mouth of the Tees to London. The Mandale Cut was the shorter of the two, at about 220 yards (200 m), with the Portrack Cut being considerably longer, although the northern meander it removed was smaller than the southern meander. Neither meander is visible today, except for the flow of Stainsby Beck into a waterway which is marked on maps first as "The Fleet" and then "Old River Tees". The current Tees Barrage is close to the site of the Mandale Cut.

Since the cuts were made, the river has continued to undergo alterations on its bed and banks to make it deeper and more navigable. The channel has been made considerably narrower by dumping ship's ballast and ironworks slag along the former banks, increasing the scouring due to its natural flow. Maps made prior to 1900 show that between Stockton and Middlesbrough the river flowed in a channel up to 330 yards (300 m) wide in places, with many shoals and sandbars. The modern channel varies between 110 yards (100 m) and 220 yards (200 m) or even a bit more.

Legends and folklore

Peg Powler is a hag in English folklore who is said to inhabit the River Tees.

In popular culture

The River Tees was featured in the television series Seven Natural Wonders as one of the wonders of the North, and in the post-apocalyptic drama The Last Train having blown its banks.
