On Sunday Harrow Lodge Park volunteers, in the east London borough of Havering, discovered hundreds of dead fish, washed up and floating in the shallows of the large lake, which is fed by the River Ravensbourne.
Tom Waller, 61, who discovered the dead fish, described the scene as "upsetting."
Havering Council's clean-up operation was launched yesterday, alongside an investigation into the cause of death.
Mr Waller, a park volunteer for two years, said: "There was some fish still alive and gasping for air when I got there. To walk along the edge of the lake and see that is quite upsetting."
