The Environment Agency are to visit Wootton Bassett businesses after the death of around 400 fish in Jubilee Lake.

Hundreds of fish were removed on September 4 after an “incident” caused oxygen levels in the water to drop leaving residents “horrified”.

While the Environment Agency (EA) initially said an algae bloom could have been responsible, it has followed up with “the initial view of the EA is there was some sort of discharge, which could have been sewage, detergents, farm effluents”.

The spokesperson added: “The Environment Agency are aware of the heavy rain we have had in the area, and that this has “flushed through” whatever was coming into Thunderbrook, down into Jubilee Lake.”Dead fish were spotted at Jubilee Lake in Royal Wootton Bassett (Image: Public)

Wessex Water confirmed to the EA that a check on their infrastructure found no sewage leaks from the main sewage pipes.

In a September 30 update, a Royal Wootton Bassett Town Council spokesperson said that in the next two weeks the EA will focus on waterways leading into Thunderbrook, a stream that feeds Jubilee Lake.

Investigations will include looking at all the tributaries, gullies and culverts entering Thunderbrook and revisiting nearby businesses.

Following the discovery of dead fish, fishing was suspended at the lake. The Angling Club have now returned and the grounds team are monitoring the area.

The next EA update is expected by mid or late October once this period of investigation concludes.
