River Crane

The River Crane is a small tributary of the Thames in West London. It runs for 13.6 kilometres through three boroughs—Hillingdon, Hounslow and Richmond upon Thames—before joining the tidal Thames near Isleworth. Though much of its drainage basin is built up, stretches of flood-meadow survive as green corridors. Where it passes Cranford Countryside Park and Crane Park, the river keeps a narrow, semi-natural vale. Heathrow’s car parks once stood on Cranford Heath, part of the old Hounslow Heath, and the Crane still skirts their edges. The Crane’s history is shaped by engineering. In the 17th and 18th centuries the Duke of Northumberland’s River was dug to power mills that once turned calico and grain. The mills have gone, but the Shot Tower from the old gunpowder works remains in Crane Park. The river’s course was straightened and dredged many times, and today treated effluent from Mogden Sewage Treatment Works is piped to the upper estuary rather than released here. A 2011 valve failure sent raw sewage into the watercourse for two days, killing three thousand fish. Walkers can follow the Crane through Crane Park’s Local Nature Reserve on its island millpool. The Shot Tower stands beside the path, a reminder of the gunpowder mills that operated until 1927. Further east the river passes Cole Park and Cole Park Island before reaching tidal reaches near Twickenham. The Duke of Northumberland’s River splits off again at Kneller Gardens, and the Whitton Brook joins at Cole Park Allotments. The valley remains a slender green thread across west London, linking parks and former heathland.
