Brockwell Park cygnet deaths: Lambeth Council letter, Brixton 2026

Key Points

• A local resident has sent an open letter to Lambeth Council accusing it of mismanaging water levels in Brockwell Park ponds, which they say contributed to the deaths of cygnets.
• The letter states that four cygnets died this year, and a fifth has since died in the intervening days after the letter was first sent.
• The resident claims fish normally visible in the ponds are no longer there, raising concerns about longer-term biodiversity impacts.
• The Swan Sanctuary has intervened in the incident, and the resident says it took the deaths and the sanctuary’s involvement to prompt action to add water to the ponds.
• The letter questions why park officers were slow to recognise risks and act, and asks whether officers are properly trained.
• It references a public notice about investment needed to rebuild a nearby borehole and asks why income from Brockwell Hall, the café/events and Brockwell Barn cannot be used to fix water-level problems permanently.
• The resident suggests money raised through park assets may be siphoned off to balance other parts of the council budget and calls this “not acceptable on a long term basis”.
• The letter proposes different management arrangements, citing Crystal Palace Park’s improvement following the establishment of a trust.
• The resident says they have lived in Brixton for over 35 years and visit Brockwell Park four to five times a week.
• The letter is addressed to Lambeth Council’s Head of Parks and Cabinet Member for parks and green spaces, and names Cllr Kane; it also references the Green Flag Award Scheme and Brixton Buzz.

Brixton (South London News) July 17, 2026 – A local resident has published an open letter to Lambeth Council alleging that mismanagement of water levels in Brockwell Park’s ponds has contributed to the deaths of cygnets and harmed the ponds’ biodiversity. As reported by the editor of Brixton Buzz, the letter was sent to the council last week but had not received a reply after ten days, prompting its publication as an open letter; in the intervening period, a fifth cygnet died.

How many cygnets have died and what role has the Swan Sanctuary played?

The letter states that four of this year’s cygnets have died and that a fifth has since died after the letter was first sent to the council.

It adds that it took the death of three cygnets and intervention by the Swan Sanctuary to prompt some action and for water to be added to the ponds.

The Swan Sanctuary has previously provided updates on the Brockwell Park cygnets, reporting losses and the condition of surviving birds.

What biodiversity concerns has the resident raised about the ponds?

The resident writes that the mismanagement of water levels has

“no doubt seriously damaged the longer-term biodiversity of the three ponds”,

citing the disappearance of fish that are ordinarily visible. They warn this will have knock-on effects for other birds that rely on the fish as a food source.

The letter also notes that volunteers working to improve the third, smaller pond have repeatedly raised concerns with park staff about silt and the need to clear it to provide a safer environment for wild fowl that breed there.

Why does the resident question the council’s response time and officer training?

The letter asks why it took so long to recognise the risks, take action and resolve the problem, given that water levels in the ponds have always fallen considerably during dry spells, though rarely to the levels seen in recent months.

It states that officers with responsibility for the parks should have been well aware of the potential for dropping water levels to have serious effects on wildlife, including the swans. The resident asks:

“Are your officers not trained to manage this or to think effectively?”

What funding and management arrangements does the letter propose?

The resident references a public notice indicating that investment is required to rebuild a borehole located nearby.

They note that parks staff repeatedly advise that Brockwell Live is necessary in part to maintain investment in the park, and that the council receives significant income from Brockwell Hall (café/events) and Brockwell Barn.

The letter asks why some of that income cannot be used to sort out the water-level problem on a permanent basis. It adds:

“I suspect that you simply siphon off the money that is raised through park assets to balance other parts of the Council budget – something which is frankly not acceptable on a long term basis.”

What alternative management model is suggested, and what response is sought?

The letter suggests that the incident points to a need to consider different management arrangements for the park, citing Crystal Palace Park’s improvement following the establishment of a trust to oversee its management and long-term investment.

The resident says they look to a response to the points raised and hope to get a sense that action will be taken to ensure no repeat of the incident.

They also state they would be interested to know what Cllr Kane thinks of the matter and her views on the longer-term management of the park, adding that Brixton Buzz and the Green Flag Award Scheme will also be interested in the response.

What does the letter say about local councillors and previous concerns?

The letter notes that the three Green councillors in the ward

“have not been bothered to provide responses to our concerns about the park which we raised previously”.

It is addressed to Lambeth Council’s Head of Parks and the Cabinet Member with responsibility for parks and green spaces, and specifically names Cllr Kane. The resident states they have lived in Brixton for over 35 years and probably go to Brockwell Park at least four to five times per week.

Background

The letter was first sent to Lambeth Council concerning the death of cygnets in the Brockwell Park pond and was later published by Brixton Buzz as an open letter after ten days without a reply. In the intervening days, a fifth cygnet died, according to the publication.

The Swan Sanctuary has been involved in the incident, with previous updates noting losses among the cygnets and the condition of those remaining.

The letter references broader concerns about park management and funding, including income from Brockwell Hall and Brockwell Barn and the role of Brockwell Live in maintaining investment in the park. It also cites a public notice about investment required to rebuild a nearby borehole.

Prediction

If Lambeth Council does not provide a prompt and substantive response to the allegations about water-level management and cygnet deaths, local residents and park users are likely to increase pressure through open letters, media coverage and engagement with bodies such as the Green Flag Award Scheme.

For regular park users, wildlife volunteers and local biodiversity advocates, continued delays or perceived inaction could deepen concerns about the long-term ecological health of the ponds and the adequacy of officer training and oversight.

For the council, the risk is that the issue becomes part of wider scrutiny of park management and funding arrangements, especially given existing debates about events such as Brockwell Live and the use of income from park assets.

If the council signals clear remedial steps—such as using income from park facilities to address water infrastructure, reviewing officer training and considering alternative management models—the immediate pressure from residents may ease; if not, further public criticism and potential escalation through local media and community groups is likely.
