Save Radley Lakes campaigners staged a peaceful protest today in the battle against RWE npower's plans to dump fuel ash into Thrupp Lake.
About 250 supporters gathered at Abingdon Guildhall at lunchtime to voice their objections to the power firm's plan.
A dozen speakers, including Abingdon Mayor Peter Green and the area's MP Evan Harris, addressed the crowd outside the hall.
Mr Green said: "When something is wrong - and this is wrong - you've got to stand and be counted to stop it.
"It's for our kids and our kids' kids."
Yesterday Save Radley Lakes campaigners welcomed a decision to halt work after a bird's nest was discovered at the site.
RWE npower said the development, which will eventually take ash from Didcot Power Station, would be delayed until "late summer".
The firm is adamant its work is necessary and has taken on an independent ecologist to monitor the land.
