The River Anker is a river in England that flows through the centre of Nuneaton. It is a major tributary of the River Tame, which it joins in Tamworth. The name of the river derives from an old British term for winding river. From source to river mouth at Tamworth is 50 kilometres (31 mi).
The river rises near Wolvey and flows in a north-westerly direction to pass between Bramcote and Burton Hastings, it is designated a main river at Stretton Baskerville where it also forms the boundary between the boroughs of Rugby, Nuneaton and Bedworth. On the outskirts of Nuneaton it collects the Sketchley Brook, and then passes alongside the Liberty Way sports stadium. At this point the river splits, with a flood relief channel to the north, and the main channel passing through the Nuneaton town centre. The relief channel re-joins beyond the town at Weddington, where the river then continues in the same north-westerly direction to pass the village of Caldecote, then Mancetter and Witherley, before reaching Atherstone where it is joined by the River Sence.
Downstream of the confluence, it reaches Grendon and then flows through Polesworth before passing beneath the M42 motorway. Beyond the motorway it passes through Alvecote Pools and meadows, a 128 ha (320 acres) Site of Special Scientific Interest (SSSI) and nature reserve. It continues past Amington Hall before turning south-westerly to flow through Tamworth and join the River Tame near Tamworth Castle.
The flow of the Anker has been measured at a gauging station in its lower reaches at Polesworth since 1966. The catchment to the station of 386 square kilometres (149 sq mi) yields an average flow of 3.2 cubic metres per second (110 cu ft/s). The highest river level recorded at the station occurred on the 25 November 2012, with a height of 2.57 metres (8 ft 5 in) and a flow of 128 cubic metres per second (4,500 cu ft/s).
The catchment upstream of the station has an average annual rainfall of 653 millimetres (25.7 in) and a maximum altitude of 275 metres (902 ft) near Bardon Hill in Charnwood Forest at the north-eastern edge of the basin.
The River Anker has flooded Nuneaton town centre several times in the past, including 1968, prompting the construction of a 600-metre-long (2,000 ft) flood relief channel in Weddington in 1976.
