{{Catchment Information
|Information=The Thames river basin district covers over 16,200km2. It encompasses all of Greater London and extends from north Oxfordshire southwards to Surrey and from Gloucester in the west to the Thames Estuary and parts of Kent in the east. In total over 15 million people live in the Thames district with many entering daily to work or visit. In addition to Greater London, other urban centres in the river basin district include Luton, Reading and Guildford. The Thames river basin district has a rich diversity of wildlife and habitats, supporting many species of global and national importance from chalk streams such as the River Kennet to the Thames Estuary and salt marshes. The management catchments that make up the river basin district include many interconnected rivers, lakes, groundwater, estuarine and coastal waters. These catchments range from chalk streams and aquifers to tidal and coastal marshes. The river basin district is mostly rural to the west and very urban to the east where it is dominated by Greater London. Around 17% of the river basin district is urbanised and the rural land is mainly arable, grassland and woodland. The economy is dominated by Greater London and the finance sector.

|Information=''Measures in the Cherwell catchment''


==Upload files==
Catchment partnerships: The Cherwell and Ray catchment partnership is hosted by the Berks, Bucks and Oxon Wildlife Trust (BBOWT) and consists of the Environment Agency, Natural England, Cherwell District Council, Banbury Town Council, Thames Water, the RSPB, Upper Thames Fisheries Consultative, and the National Farmers' Union (NFU).
The priority river basin management issues to tackle in this catchment, affecting both surface water and groundwater, are diffuse pollution from agricultural run-off, pollution from waste-water (including from sewage treatment works) and heavily modified channels.
Contribution to environmental outcomes for 2021


[[Special%3AUpload]]
* Cherwell: A project focusing on restoring a more natural river channel and fish passage through Spiceball Country Park in Banbury, a well-used public amenity, will result in improvements in the status of fish, invertebrates, macrophytes and sediment in the River Cherwell by 2021. It will also engage with local communities to raise awareness about sustainability, water quality and biodiversity.
* Oxon Ray: A project to implement measures described following a walkover survey will reduce diffuse pollution and sediment input from agriculture.
Future aims
With additional funding even more could be achieved. The following outlines projects and outcomes that could be realised with additional partnership funding.
Additional measures with £100,000 per year:
* Cherwell: Action on the River Cherwell to create more backwaters between Banbury and Oxford, involving landowners, BBOWT and community groups. This will re-naturalise the river corridor, attenuate water flow and provide habitat for fish and invertebrate species. (If £100,000, one backwater; if more funding available then more sites will become possible).
* Oxon Ray: Initiate landowner engagement and advisory programme similar to Catchment Sensitive Farming in the Ray catchment. This will reduce agricultural diffuse pollution and increase resilience to flooding events.
*Cherwell: Action on River Cherwell to monitor and quantify abstraction issues with the Oxford Canal.
Additional measures with £1 million per year (as above plus the following):
* Cherwell: Major infiltration project in the catchment, with involvement of Thames Water and the NFU, involving landscape interventions designed to increase surface water infiltration, increase water storage capacity and attenuate overland flow during peak rainfall events (with potential benefits for flood alleviation). This will help to resolve rural diffuse pollution and phosphate failures.
* Oxon Ray: Major flood plain meadow restoration projects along the River Ray, re-connecting the flood plain and re-instating natural river features and riparian habitat. This will improve water quality and nutrient cycling, increase habitat for fish and invertebrates, provide ecosystem services and benefits for leisure, education and public access.

  • Evenlode - to mitigate remaining impoundments and re-naturalise the Glyme from Stratford Bridge to Glympton involving the local authority, landowners and community groups. This will join up restored areas and tackle rural diffuse pollution.
  • Evenlode - address barriers to fish passage and create in-channel habitat enhancements at Charlbury. This will help resolve failures in fish, invertebrate and macrophyte populations and improve amenity and recreational value.
  • Windrush - a fish passage and wetland creation project at the confluence of Great Brook and Thames; this will create a backwater refuge for fish and invertebrates and provide some additional flood storage capacity.
  • Windrush - further action to address rural diffuse pollution and channel damage.

Additional measures with £1,000,000 per year (as above plus the following):

  • Evenlode - infiltration project, involving strategic woodland planting and other landscape interventions to attenuate overland flow during peak rainfall events (with potential benefits for flood alleviation and climate change resilience). It will tackle rural diffuse pollution and phosphate failures, and contribute to Biodiversity 2020 targets. It is part of a wider partnership project across the Upper Thames tributaries.
  • Windrush - major project to restore degraded ecosystems along the flood plain of the Thames from source to Oxford. It would target connectivity of riparian and aquatic habitats and contribute to improving flood management, water quality, soil quality and recreation. It would seek to establish more integrated environmental governance across the Upper Thames and promote further academic research.
