DE PERE, WI-- It's a community effort to help clean rivers in Northeast Wisconsin.
The Fox-Wolf Watershed Alliance held their 2nd annual Fox River clean up.
People volunteered at more than 20 different sites across the area, picking up debris and waste.
After the clean up, people gathered at Voyageur Park in De Pere to celebrate.
"Once the snow is gone there's a lot of pollution that has kind of been stuck under the snow all winter, so it's great to pick that up," said Mariah Pace of the Fox-Wolf Watershed Alliance.
More than 350 people participated in this year's event.
