Basin features

The River Crane, a tributary of the River Thames, runs through part of west London, England, in the historic county of Middlesex. The Crane flows 8.5 miles (13.6 km) through three London boroughs: Hillingdon, Hounslow and Richmond upon Thames. The drainage basin is heavily urbanised but the old flood-meadows of the river corridor provide a continuous belt of semi-natural habitat. In common with many urban rivers, the Crane's natural form has been greatly altered by river engineering works: over the years the watercourse has been subject to widening, narrowing, straightening, dredging and bank reinforcement.


The river's source is a point south of North Hyde Road in Hayes, Hillingdon, from where its course is near semi-circular to the south then east, joining the tidal Thames on the border of St Margarets and Isleworth, just to the south of Isleworth Ait.

Passing through Cranford, the river crosses Cranford Countryside Park, skirts the eastern side of Heathrow Airport's car parks (formerly the Cranford Heath part of Hounslow Heath) and North Feltham, the latter split from Hounslow West on the other bank by most of what is left of Hounslow Heath; here the (Upper) Duke of Northumberland's River joins the Crane. From this point, the Crane turns gradually east and passes through Crane Park (in Whitton, Twickenham). In Crane Park is the site of the Hounslow Powder Mills which were built in the 16th century and continued to make gunpowder until 1927. The mills have disappeared, but the Shot Tower still stands nearby. The large millpool on an island above the mills is now a Local Nature Reserve, Crane Park Island. A distributary splits off (forming a second section of the Duke's River) at Kneller Gardens. The Crane itself flows north east through central Twickenham and then north through the Cole Park area. The river is tidal in the final stretch between Cole Park Island and the confluence with the Thames. The Lower Duke's River is tidal for the short distance below the weir by the bridge in Church Street, Isleworth, to its confluence with the Thames. Upstream in Isleworth it has been diverted to flow through Mogden Sewage Treatment Works, where it provides coolant for the power station. Treated sewage effluent from the works is not discharged here but is instead piped to the Thames at Isleworth Ait.

The Crane in major part delimits the London boroughs of

When extending the Piccadilly line from Hounslow West to Heathrow Airport, the high water table of the ground beneath the Crane made it impractical to tunnel under the river channel, so the lines briefly emerge from their tunnels here and cross over the watercourse via a bridge.

Its name is interwoven with Cranford and may be from crane (bird)s.

Associated watercourses

  • Duke of Northumberland's River: this man-made river has two distinct sections, constructed at different times. The Upper DNR is a tributary of the Crane but also a distributary of the River Colne, Hertfordshire. It flows from the Colne at Longford to the Crane at Hounslow. The Lower DNR is a distributary of the River Crane, flowing from the diffluence at Whitton to the Thames at Isleworth.
  • The Yeading Brook is the Crane's upper reach and is 16 miles (25.8 km) long. Before the 19th century it was also referred to as the River Fishbourne. It rises in the ground between the northwest London suburbs of Pinner and Harrow and also rises (in part) from Headstone Manor moat, and follows a meandering course through North Harrow, southern parts of Ruislip then through Ickenham Marsh nature reserve, before skirting Northolt Aerodrome west of Northolt. To the south of the aerodrome the Roxbourne Brook [also seen in maps as the Yeading Brook (East Arm)] joins it from Roxeth South Harrow. From here the Yeading Brook flows ESE through parkland separating Yeading from Hayes before finally turning south to pass through Bulls Brook Business Park, Hayes, which is its final stretch before becoming the Crane directly west of the A312 "The Parkway" and of the Bull's Bridge junction of arms of the Grand Union Canal. This junction is the tripoint of Hayes/Harlington/Cranford.
  • The Ickenham Stream flows into the Yeading Brook directly upstream of the A40 Western Avenue roadbridge in the London Borough of Hillingdon. This watercourse was originally constructed in the early 19th Century to convey water from a Grand Junction Canal feeder reservoir which in the 1930s became Ruislip Lido.
  • Frogs Ditch flows from south west Hayes, crossing under the M4 motorway before running along the western and southern boundaries of Cranford Countryside Park to join the River Crane immediately upstream of the Cranford Lane road bridge at the southern end of the park.
  • The Whitton Brook flows into the River Crane at the Cole Park Allotments site.

Catchment partnership

The Crane Valley Partnership (CVP) is the relevant 'Catchment Based Approach' (CaBA) catchment partnership providing the strategic co-ordination of efforts to manage and improve the River Crane and its tributaries, including enhancing biodiversity, water quality and quantity, connectivity, public access, community cohesion, and historical and educational opportunities. The CVP's origins lie with the West London Biodiversity Practitioners Group (WLBPG), derived from the partnership that formed during the work on the Hounslow Local Biodiversity Action Plan (LBAP). The WLBPG held its first meeting on 13 November 2002, at Heathrow's Mayfield Farm classroom. The original members included: London Borough of Hounslow, London Borough Hillingdon, Groundwork Thames Valley, Syon Park Estate, Thames Water, Heathrow Airport Ltd, Glendale/British Airways, English Nature, London Wildlife Trust (LWT), Royal Society for the Protection of Birds (RSPB).

The main objective of this group was to encourage practical implementation of conservation work across West London. The group met again in February and July 2003. The partnership then evolved to become the River Crane Management Forum (RCMF), which had its first meeting on 15 June 2004. Members present were:

These organisations had a mutual aspiration for joined-up action along the River Crane to improve water quality and biodiversity, as well as promoting the significance of the river corridor as part of the West London Green Chain. The Forum had another meeting on 20 July 2005, at which point the Crane Valley Partnership (CVP) was established. CVP has become hosted and chaired by the educational charity Green Corridor.

In April 2013, the Partnership appointed a Development Manager who is employed through the charity, principally through £400,000 pledged for spending over a course of years, by Thames Water after the 2011 incident.

The CVP is formed of five London boroughs and public, voluntary and private stakeholders, working towards a shared vision: for a well-managed and high quality river corridor which is accessible to all, in which wildlife can thrive and local people can take pride and ownership.
