A group of Rotarians filled 60 bin bags with rubbish during a litter pick at Watermead Country Park.
The park, near Thurmaston, is filling up with rubbish faster than park rangers and their helpers can clear it up, due to repeated floods washing debris down the Grand Union Canal from Leicester.
Since November there have been six big floods, the most recent of which was caused by snow melting.
Members of The Rotary Club of Wreake Valley were at the park on Saturday to help.
A senior ranger at the park said: "We had about 20 volunteers down there on Saturday.
"They found stuff that had washed down from Leicester, including trolleys, TVs and golf clubs.
"Every time there's high water, rubbish gets picked up in Leicester and comes down over the weir in Thurmaston and into the park.
"This winter we've had more than 200 bags of rubbish collected and we're only scratching the surface.
"We're very glad people come down to volunteer. We have a group that comes once a month and individuals who pick rubbish up as they're walking."
