Location

The Crane has always been so marked in maps of Cranford, rather than as the Yeading Brook. Here the east end of North Hyde Road in the far south-east of Hayes has a bridge which is on the boundary between the two districts (and the traditional parishes), from where its course is nearly semi-circular to the south then east, joining the tidal Thames at the boundary of St Margarets and

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 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 Tideway (upper estuary of the Thames) at Isleworth Ait. The Crane in major part delimits the

Pollution incidents


October 2011

engineers carried out routine maintenance. Unable to force it back open, they arranged for the backed-up sewage to be taken away in tanker lorries for treatment. The volume of sewage meant tanker removal could not keep pace. Faced with a choice between letting the excess sewage back up into basements of Bath Road hotels and various airport roads or spill to the Crane, the much cheaper option prevailed, resulting in discharge until 3am on Monday and damaged wildlife. This killed 3,000 fish.Pollution incident on the River Crane kills thousands of fish

Three days later, a temporary coffer dam of sandbags spanned the river, just north of the Piccadilly Line bridge. A bulk road tanker with flexible hoses extracted polluted water above this.

Catchment partnership

The Crane Valley Partnership (CVP) is the relevant 'Catchment Based Approach' (CaBA) catchment partnership. It strategises and co-ordinates efforts to manage and improve the Crane and its tributaries, including enhancing biodiversity, water quality and quantity, connectivity, public access, community cohesion, and historical and educational opportunities. In summary, CVP aims to restore one of London’s most natural river systems, conserve surrounding habitats and improve public access so that nearby communities can enjoy contact with the natural world. CVP stemmed from the West London Biodiversity Practitioners Group, derived from the partnerships of the Hounslow Local Biodiversity Action Plan. The Group held its first meeting on 13 November 2002, at Heathrow's "Mayfield Farm" classroom. The original members included: teams from the London Boroughs of Hounslow and 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 the Group was to encourage local conservation work. The Group reconvened the next February and July. The partnership then evolved to become the River Crane Management Forum (RCMF), which had its first meeting the next June. Members present were: *

These agreed an aspiration for action along the 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, when the CVP was established. Up until 2021, its meetings were customarily hosted and chaired by an educational charity: *Green Corridor In April 2013, the Partnership appointed a Development Manager employed through this charity, initially utilising a sum of £400,000 provided by Thames Water following the 2011 incident. More recently CVP's staffing/administration costs have been met by annual contributions from a number of the partner organisations including Thames Water. In 2021 the hosting/chairing service was taken on by the Crane Valley Community Interest Company (CVCIC), specifically set up for this purpose ompany Number:13302764
