Thames21 explores ways to boost fish populations in the River Ching
Environmental charity Thames21 is working with partners to produce a series of feasibility studies and designs to explore removing physical barriers, such as weirs, to enable fish migration in the River Ching.
The work forms part of a ‘Ching Action Plan’* to remove or modify structures within the River Ching – a river which originates as a small stream in Epping Forest and flows for approximately 10km through, and into, the River Lea.
As is the case with most North London rivers, the River Ching is heavily modified with multiple weirs, structures, culverts, and stretches of concrete channel, which can block fish passage. The river has been artificially straightened, widened, and deepened in places. Although the River Ching is home to an array of wildlife such as perch, stone loach, European eel, and stickleback, fish biodiversity has declined in recent years due to physical barriers, pollution and poor water quality.
The plan identifies suggestions for nine fish passage improvement projects and 14 habitat improvement projects along the River Ching. Overall, it highlights actions that can be taken to boost the wildlife in this river.
Becca Turnpenney, Thames21’s Catchment Partnership Development Officer, said: “We know that tackling barriers to fish migration will improve the population of fish species in the River Ching. Currently fish passage is restricted due to physical barriers, but by mitigating these, it will permit movement of fish along the entire watercourse. Fish passage improvement projects also allow natural processes to return to the river, encouraging water to flow more naturally, promoting flow diversity, creating better habitats for a variety of aquatic life.
“This is why, over the next year, we will be exploring innovative ideas with our partners to help remove these barriers. These studies are about pushing the boundaries and seeing what’s possible, so that we can help to improve the health of the River Ching for the benefit of people and wildlife.”
Janet Laban, Joint Lead of the River Ching Action Group, said: “The Ching Action Group is keen to work in partnership with Thames 21 and others on this exciting project. We look forward to seeing biodiversity and water quality improvements as the project progresses.”
Caroline Haines, Chair of the City of London Corporation’s Epping Forest and Commons Committee, added: “The River Ching begins in Epping Forest, but its influence reaches far beyond. This next phase of the Ching Action Plan is a vital step toward restoring the river’s natural flow and supporting its rich aquatic life.
“By improving fish passage and habitats, we’re not only enhancing biodiversity within the Forest, but also strengthening the ecological resilience of the wider area for generations to come.”
Cllr Clyde Loakes, Deputy Leader and Cabinet Member for Climate and Air Quality at Waltham Forest Council, added: “The River Ching is a really special part of our borough’s natural environment, and we’re committed to working with partners like Thames21 to restore and protect it. Removing barriers to fish migration and improving habitats will help wildlife flourish and make the river healthier for future generations. This project reflects our wider ambition to tackle the climate emergency and enhance biodiversity, creating cleaner, greener spaces for local people to enjoy. It’s great to see practical action like this making a real difference on the ground.”
