What do volunteers do?
Volunteers start the morning at their assigned sites to clean up garbage and debris. You will be supplied with gloves, trash grabbers, bags, and everything else you need.
Then, at noon, volunteers are invited to join us for the annual Cleanup Picnic to enjoy lunch, music, bounce houses, raffles, and games. It’s fun for the whole family!
There are 65+ cleanup sites located along the Fox River, the Wolf River, Lake Butte des Morts, Lake Winnebago, Lake Winneconne, the East River, the bay of Green Bay, and more throughout the Fox-Wolf River Basin.
