Ravensbourne sub catchment
Catchment partnership vision
Our shared partnership vision is of improved rivers providing wider benefits for people and nature at a catchment scale. Where public voices are listened to so that key enhancement and improvement opportunities for our rivers are identified, where new development enhances the river, allowing nature to thrive and enabling opportunities for leisure, education and discovery to benefit local people, and where community volunteer groups are well supported in their work along the river. Our vision also includes these improved rivers being a diverse natural environment with a mosaic of habitats in connected green corridors, where species can move freely and thrive along clean water river corridors. We envisage this connectivity being enjoyed by local communities too: a place where public access to nature is widespread and nature is respected and protected. We aim for a future where the threat of flooding is vastly reduced and strong partnerships between stakeholders ensure communities are protected against climate change impacts and encouraged and fully supported to become stewards of their local river.

Catchment challenges
Current challenges identified by partnership
Physical modifications
Much historic engineering no longer serves the original purpose leaving habitats disconnected and poor river function
Pollution from towns, cities and transport
Numerous outfalls contribute to poor water quality from road runoff and misconnected foul water discharges
Invasive Non-native Species
Problem invasive plants spread across often inaccessible areas with multiple landowners needing strategic controls
Wider water environment challenges identified by partnership
Reduce storm overflows and drainage system incidents
Storm overflows and drainage incidents are frequently impacting water quality within the catchment
Build environmental resilience and adaptation to climate change
Ravensbourne catchment is highly urbanised so it is very important to protect the catchment and homes from flooding and drought
Removing plastics/litter from the water environment
Plastic pollution is a major problem in the catchment, impacting wildlife and preventing people from enjoying their blue spaces
Connecting communities with nature
Engage the wider community and improve access to blue-green spaces to improve health and wellbeing and ensure successful projects in the long term
Support Nature Recovery Network and Local Nature Recovery Strategy
Many sites are valued and supported by communities, if included in the LNRS, conservation will have a catchment-wide focus and will benefit rivers
Support levelling up, growth and jobs
All activities in the catchment (including development) must enhance biodiversity and the skills and employment opportunities of local communities
Future challenges predicted by partnership
Physical modifications
Many rivers in the catchment have been historically dredged and impounded
Pollution from towns, cities and transport
Drainage and road run-off are significant pollution sources within this heavily urbanised catchment
Pollution from waste water
Densely populated catchment with frequent waste water pollution events
Future challenges predicted by Environment Agency
Future challenges in 2050
- Pollution from Towns Cities and Transport
- Invasive Non-native Species
- Changes to the Natural Flow and Water Levels
Emerging challenges
- Changes to the Natural Flow and Water Levels
- Pollution from waste water
- Pollution from Towns Cities and Transport
Partnership success highlights 2016 to 2021
Since 2016, the Ravensbourne Catchment Improvement Group, established in 2012, has engaged many varied members including different council representatives in the London Boroughs of Lewisham and Bromley, Thames Water, the Environment Agency and local groups throughout the catchment. Our river champions and volunteers include the Quaggy Waterways Action Group (QWAG) and the Friends of the River Pool who meet regularly to carry out bankside and in-channel work to improve biodiversity and habitats as well as post-restoration habitat management at sites such as Brookmill Park, Manor Park, Cornmill Gardens, Ladywell Fields, Chinbrook Meadows and Sutcliffe Park. These incredible community groups also run long-term catchment-wide projects, like the annual 3 Rivers Clean Up which helps to reduce the prevalence of invasive non-native species (INNS) and remove litter across the three London boroughs (Lewisham, Bromley and Greenwich). Local groups and volunteers have also completed educational events for all ages, raising awareness of the many complex issues affecting the rivers and streams of the Ravensbourne Catchment. For example, volunteers are trained to carry out riverfly surveys every month at several spots around the catchment to monitor water quality and quickly detect pollution incidents. Our partnership has raised and continues to raise the profile of all of these river improvement activities through our webpages, social media and local networks.
Partnership development plans
In future years we would like to include more partners in the partnership, combine volunteering activities among the catchment’s three councils, encourage more visits to other London boroughs to learn from others, and look into funding opportunities with local businesses. We want to make the catchment’s rivers more accessible, extend restoration works across the upper and lower reaches, undertake more natural flood management (NFM) projects in the upper catchment, restore the River Quaggy and provide better habitat and passage for fish across the catchment. We want to develop a clear plan and better communication amongst partners to ensure all of these future projects lead to improvements at the catchment scale as well as at the local scale of a project’s section of river. Similarly, we want to see participation from a variety of stakeholders in the Local Nature Recovery Strategy to identify and support potential opportunities to enhance the aquatic environment within the catchment.
