River Tame, West Midlands
Skirting to the north of Castle Bromwich, it leaves Birmingham to the north-east at Park Hall Nature Reserve, passing Water Orton in Warwickshire. At Hams Hall, immediately after its confluence with the River Blythe and the little River Bourne, it turns sharply to take up a northward course, and soon feeds into the large complex of water purification lakes at Lea Marston that now make up Kingsbury Water Park. It then crosses into Staffordshire, flowing through Middleton Lakes RSPB reserve in a wide valley between Drayton Bassett to the west and Dosthill to the east. It then flows under Watling Street to the east of Fazeley, and under an aqueduct carrying the Coventry Canal. It continues northward to Tamworth, which takes its name from the river, where it is joined by the River Anker immediately to the east of Lady Bridge beneath the strategically positioned Tamworth Castle. The river continues its generally northward route past Hopwas, Comberford and Elford until it arrives at the National Memorial Arboretum where it forms the boundary between this and the Croxall Lakes Nature Reserve. After this, it flows under the railway at Wichnor Viaduct to its confluence with the Trent near Alrewas. The eventual outflow is into the North Sea, via the Humber Estuary. When the Tame and Trent meet, the Tame is the bigger river, the Trent effectively joining it as a tributary. However, the Trent being the "longer" river at that point is considered the more senior, and so the combined river bears its name.
The catchment of the Tame covers an area of nearly 1500 km² and contains a population of about 1.7 million people. Approximately 42% of the Tame basin is urbanised, making it the most heavily urbanised river basin in the United Kingdom.
