Residents Devastated as Toxic Algae Kills Swan Family
4 Aug
Summary
- Swan family died after being exposed to toxic blue-green algae.
- Canvey Lake had high levels of blue-green algae, over 100 times the warning threshold.
- Millions were allocated for lake restoration after the environmental disaster.
A devastating loss of a swan family has occurred at Canvey Lake in Essex, with residents reporting deep sadness and devastation. The swan parents and three cygnets died on Friday, having been transferred to South Essex Wildlife Hospital due to concerns about the deteriorating condition of the lake. This incident is attributed to blue-green algae, confirmed by wildlife hospital founder Sue Schwar as the cause of death.
Environmental concerns surrounding Canvey Lake have been escalating. In July 2025, testing revealed blue-green algae levels at 2.5 million cells per millilitre, far exceeding the 20,000 cells warning threshold. This led to the surrender of the lake's lease and prompted action from local councils. Blue-green algae, a toxic scum on water, poses a significant threat to wildlife.
Castle Point Borough Council expressed deep sorrow over the swans' loss and acknowledged the community's distress. Recent tests confirmed the presence of blue-green algae, a phenomenon exacerbated by hot weather and drought conditions affecting water bodies across the region. The council stated that plans for major restoration works, backed by £1 million in funding, are proceeding to address the issues at Canvey Lake.
