Come on an Outfall Safari and help us raise awareness about river pollution!
It is five years since we ran our first Outfall Safari along the Ravensbourne river catchment and it’s time to run another health check on our rivers. This is an opportunity for volunteers from Keston to Deptford, from Eltham to Sydenham, to join us and help identify pollution hotspots and raise public awareness around drainage misconnections that can harm our rivers.
The waterways of the Ravensbourne, Quaggy and Pool join the Thames at Deptford and, like all London’s rivers, they can be polluted by chemicals found in detergents, building material, paint etc and by sewage due to misconnected plumbing. Pipes that lead into surface water drains, rather than into sewers, bring these pollutants into our rivers and impact the species that live in them.
While Thames Water and the Environment Agency monitor the river catchment and respond to pollution incidents, it is very hard to create a detailed map of all the troublesome outfalls that have, so far, remained under the radar. An Outfall Safari is the answer.
Designed to be undertaken by local volunteers, an Outfall Safari requires no expertise beyond simple data collection, which is covered by our bespoke training in March, and keenness to take walks alongside our rivers.
This is a short-term commitment: it will be run over a period of around one month (April 2022) and relies on lots of small teams of volunteers each doing as much or as little as they want. One team member will record the observations of the group using a simple mobile App, and the uploaded data collected by all the teams will create a detailed picture of the current state of the catchment.
Outfall Safari training will be on Wednesday, March 30th from 10.30am to 12.30pm at the Althletics Hub meeting room in Sutcliffe Park Sports Centre, London SE7 5LW. Our trainer is Phoebe Shaw Stewart of the Zoological Society of London. Poster attached – training is of course free.
An Outfall Safari gathers valuable information. Data from the App is mapped and passed on the Environment Agency and Thames Water. And any severe pollution revealed can be investigated immediately by these agencies. It is a proven method of checking on London’s rivers, already tested on the rivers Crane, Wandle, Hogsmill, Dollis Brook and many more. It relies fully on Citizen Scientists! Which could be you. Please contact us you’d like to take part.

London Rivers Week: Photo Competition #PictureBlueLondon
Thames 21 write...

We are launching our annual photography competition in celebration of London Rivers Week which ran from 23-31 October 2021. CPRE London is delighted to be working with Thames21, the Environment Agency, ZSL London Zoo, the London Aquarium and others to celebrate London’s rivers and waterways.

Capture London’s waterscapes
Judges will be looking for uplifting images that capture the beauty and variety of the London’s waterscapes – whether that be landscape, wildlife, rivers, canals, a piece of history, places that heal or replenish or people enjoying London’s wet outdoor spaces. We challenge you to grab your camera or phone, explore the watery side of the capital and capture London’s countryside at its very best. We want to see it all!
This year we welcome your interpretation of three categories that represent the city’s key environmental challenges and opportunities: climate change, access to nature, and health and wellbeing. All entries should fall within one category and a winner will be chosen from each.
The photographs will be judged by an impressive line-up of key figures in London’s photography and environmental community including Shirley Rodrigues (Deputy Mayor for Environment and Energy, Greater London Authority), Dave Webb (Environment Agency) and Peter Coles (professional photographer and urban ecologist).
All our winners and finalists will be showcased on our website, featured in the next edition of our Green London newsletter and on our social media channels.
Enter the competition
Competition entry is free, and entrants can enter up to three photographs, one in each category – climate change, access to nature, and health and wellbeing.
The winning entries will receive a cash prize of £100, free membership to CPRE London for a year and tickets to the London Aquarium, plus a cuddly toy! One overall winner will also receive a free family ticket to ZSL London Zoo.
Entries close on 26 November 2021. To enter please read the webpage and terms and conditions (PDF 138 KB).
London Rivers Week is a partnership campaign run through London Rivers Restoration Group, a sub-group of the Catchment Partnerships in London. It is sponsored by Thames Water.
London Rivers Week – Saturday 23 October – Sunday 31 October 2021
(with thanks to Thames 21 for the information)
London Rivers Week is a week-long annual campaign inspiring the public to celebrate London’s rivers and the projects taking place to rewild and renaturalise them and connecting them with their local communities.
The campaign was launched by the London Rivers Restoration Group in 2016 on behalf of the Catchment Partnerships in London (CPiL) to highlight river restorations. Between 2008 and 2017 a total of 23.5km (14.6 miles) of rivers have been restored.
About the London Rivers Restoration Group
The purpose of the London Rivers Restoration Group, a sub-group of CPiL, is to promote and report on the delivery of river restoration and enhancement projects in support of the Catchment-based Approach to delivering Water Framework Directive objectives across London.
Its specific objective is to achieve the following aspirations set out in the London Rivers Action Plan (LRAP):
- Improve flood management using more natural processes
- Reduce the likely negative impacts of climate change
- Reconnect people to the natural environment through urban regeneration
- Gain better access for recreation and improved well-being
- Enhance habitats for wildlife
The London Rivers Restoration Group includes the Environment Agency, Thames21, the Greater London Authority, the South East Rivers Trust, London Wildlife Trust, ZSL, the Thames Estuary Partnership, CPRE London and Thames Water.
About the Catchment Partnerships in London (CPiL) Group
The purpose of CPiL is to support 12 different Catchment Partnerships within Greater London to share lessons, experiences, best practice and to help achieve a coordinated approach to delivering the objectives of the Water Framework Directive.
CPiL is not a Steering Group for the Catchment Partnerships; instead it supports and facilitates shared action, decision making and communication for the Catchment-based Approach in London.
Catchment Partnerships are groups of organisations working in different geographical locations to improve water quality.

Stumps Hill pond at Beckenham Place Park gets some weevils!
A water fern called Azolla, originally from America has been spreading in the British Isles in recent years and has established itself in the pond at Beckenham Place Park. It is spread by wildfowl and spore dispersal and can quickly take over a pond, swamping the native vegetation and wildlife. It can develop a floating mat 30cm thick, which shades the sunlight from the water and chokes the pond. To control this invasive weed, weevils have been introduced into the pond that eat the Azolla. This should keep it under control and prevent it from taking over the pond. This is a safe natural way to control the weed without using harsh chemicals.

New programme for Jan-March
Hi Everyone!
Here is the new Rivers and People programme for January to March. Please note, we are currently not able to run sessions due to the lockdown but we hope to be back up and running in March.
The Tweed Invasives Project
For those of you who have spent time with me and other volunteer groups in activities such as The 3 Rivers Clean Up clearing himalayan balsam know what great fun it is. You may wonder, however if it is all worthwhile? Of course we know it is because in Lewisham we have seen a huge reduction in the amount of HB in the years that we have been running the 3 Rivers Clean Up and other similar sessions.
The Tweed Invasives Project has been tackling invasive plant species in and around the River Tweed and its tributaries since 2002, when Giant Hogweed was identified as one of the biggest threats to the River. Since then, they have added Japanese knotweed and Himalayan Balsam to their list of invasives. With all this fantastic experience, they have produced a ‘best practice’ manual, The Tweed Invasives Project: 18 Years of Catchment-wide Control, which gives a detailed guide to delivering a long-term, catchment-scale invasives control programme.
It is a fantastic document highlighting all the different ways in which you can control these species. For those of you that only want to read about Himalayan balsam, you will find this from p24 onwards.
