Broken Sanctuary: A Local Artist’s View of the Carshalton Ponds Repairs
July 20, 2026 - 11 min read

When I saw Carshalton’s upper pond drained, my first thought was not simply that something needed repairing.
It felt as though one of Carshalton’s most peaceful places had been broken open.
The familiar reflections had disappeared. The water that normally softens the buildings, trees and railings was gone. Wildlife was struggling, and a place that usually feels calm and settled suddenly looked exposed and vulnerable.
For me, Carshalton Ponds are not merely a pleasant local landmark. They are a sanctuary.
They are somewhere I return to when I need inspiration, calm or a reminder of what makes Carshalton special. They have appeared repeatedly in my watercolour paintings because the scene is always changing, even when the buildings remain the same.
Light passes across Honeywood Museum. Trees move in the wind. The Greyhound is reflected in the water. A heron may stand almost completely still before suddenly disappearing into flight.
That quiet, changing atmosphere is what I try to capture in my work.
Seeing the pond empty therefore felt personal. It was not just a broken edge or a leaking section of water. It felt like a small part of Carshalton’s identity had been interrupted.
Update: the water has returned
Update, 20 July 2026: My mum drove past Carshalton Ponds and saw water back in the upper pond. Sutton Council had also confirmed that SES Water was refilling the ponds after repair work that week. This is encouraging news and shows that the repair work has progressed. At the time of writing, I have not seen an official public statement confirming that every part of the repair and refill is complete.
After seeing the pond empty and exposed, it is reassuring to know that the water and familiar reflections are returning.
Why was Carshalton Ponds drained?
In July 2026, the upper pond beside Honeywood Museum was drained so that contractors could reach and repair a leaking section of the pond edge.
The suspected leak was reported beneath or close to the railings along Pound Street, opposite The Greyhound. Sutton Council separately described it as a section of pond edge where the railings are regularly damaged on the High Street side.
Public information released at the time said that repair work was expected to begin on Monday 13 July 2026. SES Water was then expected to refill the pond once the work had been completed.
Although water is visibly back in the upper pond, I have not yet found an official statement confirming the full details of the completed repair.
What caused the leak?
Councillor Andrew Jenner reported that the problem may have involved a damaged gulley beneath or close to the railings.
The gulley is designed to allow water from the underground aquifers to flow into the pond. However, this part of the pond has repeatedly been affected by vehicles crashing through the railings.
Those collisions have damaged more than the visible metalwork. They may also have affected the pond edge and the infrastructure that helps control the movement of water.
The same local update said repairs had been considered previously, but the contractor required a road closure because of the safety risks. It reported that Transport for London did not approve that closure at the time, so the repair could not go ahead.
This is frustrating because the damage seems to be part of a problem that has developed over many years rather than something that appeared overnight.
Carshalton Ponds and the danger from traffic
The railings, walls and pond edges sit very close to busy roads. A local councillor’s update records previous incidents in which vehicles crashed through the railings and entered the ponds.
This does not only create an immediate danger to drivers, pedestrians and wildlife. Each collision risks damaging a historic structure and weakening the edges of the ponds themselves.
The road bridge, retaining walls and railings around this part of Carshalton Ponds form part of a Grade II listed structure dating from the early nineteenth century.
These features are not replaceable pieces of modern street furniture. They are part of the historic character of Carshalton.
Repairing the leak is important, but protecting the pond properly may also require a longer-term solution to prevent the same areas from being damaged again.
Did the hot and dry weather cause the water loss?
The warm and dry weather may have made the situation look worse, but the main publicly reported reason for draining the upper pond was the leak and the need for repair work.
Dry conditions can reduce natural water levels and place additional pressure on rivers, ponds and wildlife. During July 2026, soils across south-east England were reported as being much drier than average, while river flows were declining in many places.
However, the sudden draining of the upper pond was a deliberate step to allow access for repairs. It was not simply the pond drying up because of the weather.
What happened to the wildlife?
The most upsetting part of seeing the pond drained was thinking about the wildlife that depends on it.
The ponds and nearby River Wandle provide habitat for water birds, fish and invertebrates. Ducks, geese, swans and herons are familiar sights around the water.
Local residents and animal rescue groups helped protect wildlife when the water level fell. Sutton Council also acknowledged that the inconsistent water levels were creating difficult conditions for the animals and said the work would be completed as quickly as possible.
The response demonstrated how deeply local people care about the ponds. They are not simply decorative water features. They are living habitats in the centre of a busy village.
Why does the water sometimes turn green?
The recent leak is not the first challenge the ponds have faced. In previous years, local updates and improvement work have addressed green or cloudy water, algae, sediment and poor water movement.
Hot weather, bright sunlight, nutrients in the water and limited circulation can encourage algae to grow. This can change the colour of the water and reduce the clear reflections people associate with the ponds.
The ponds were drained for cleaning, desilting and repairs in 2023. A July 2026 local update also said the council’s biodiversity officer was exploring aquatic planting to help with the annual algae problem.
Carshalton Ponds may look natural, but maintaining them involves a complicated balance of historic infrastructure, underground water, wildlife, road safety and environmental management.
The beginning of the River Wandle
Carshalton Ponds mark the source of the Carshalton branch of the River Wandle. The Wandle flows north through south London and joins the tidal Thames at Wandsworth.
This makes the ponds part of a much larger local landscape. The water connects Carshalton to parks, mills, industrial history, wildlife habitats and communities across south London.
When something goes wrong at the ponds, it can feel like more than a local maintenance issue. It touches the beginning of one of London’s best-known chalk streams.
Why Carshalton Ponds matter to me
I often describe my paintings as exploring calm, sanctuary, memory and the emotional connection we form with familiar places. Carshalton Ponds bring all of those ideas together.
I do not paint them because they are perfect. I paint them because they are familiar, changeable and full of life.
There are days when the water is dark and unsettled. On other days, the surface becomes a mirror, catching the sky, Honeywood Museum and the trees around the edge. Sometimes one small area of sunlight can transform the whole scene.
As someone with ADHD, I can often feel overwhelmed by noise, activity and too many competing thoughts. Places like Carshalton Ponds offer a visual pause.
They allow me to stop, look and notice what is actually in front of me. The movement of water, repeated shapes in the reflections and gentle changes in light can create a moment of calm.
This is why the idea of a broken sanctuary felt so appropriate. The sanctuary had not disappeared, but it needed care.
Painting Carshalton Ponds
Carshalton has become one of the most important subjects in my work. I have painted its water, buildings, wildlife and reflections from many different viewpoints. Each painting records a particular moment, but also something of how the place felt to me at that time.
One of my recent paintings, The Heron’s View, looks across Carshalton Ponds towards Honeywood Museum.
The heron represents the quiet patience of the place. It stands within the landscape rather than dominating it, watching the water and waiting.
The painting was created before the recent repair work, but seeing the pond drained has changed how I look at it. It now feels like a record of something precious that should never be taken for granted.
Carshalton paintings, prints and cards
My Carshalton collection includes original watercolour paintings inspired by the ponds, Honeywood Museum, Carshalton Water Tower and other familiar local landmarks. Selected paintings are also available as art prints, greetings cards and locally inspired gifts.
These pieces are created for people who have their own connection to Carshalton, whether they live here now, grew up nearby or simply remember walking beside the ponds.
Purchasing my work also helps me continue painting and recording the places that make our local area distinctive.
Can you still visit Carshalton Ponds?
The ponds remain in a public area beside Honeywood Museum, The Grove, All Saints Church and The Greyhound. The upper pond has water in it again, although the surrounding area may still be affected by repairs or temporary barriers.
Please keep away from any working areas and give wildlife plenty of space.
The surrounding village is also worth exploring. Honeywood Museum, The Grove, Carshalton Water Tower and the historic streets around the ponds all help tell the story of Carshalton.

A sanctuary worth protecting
The water has returned to the upper pond and the familiar reflections are returning with it. I hope the wildlife will settle back into its familiar routines and people will once again stop beside the water.
But I hope the recent situation encourages us to look beyond the immediate repair.
This place needs long-term protection from repeated vehicle damage, careful environmental management and continued attention to the wildlife that depends on it.
Carshalton Ponds are part of our history, our landscape and our shared memory. For me, they are also a place of calm and creative inspiration.
A sanctuary can be damaged. It can feel broken. But with proper care, it can also be restored.
