Help clean up the waterways of the Arboretum by participating in this watershed wide clean up event.  Groups through out the Cannon River Watershed will participate at multiple sites to remove trash, plastic, tires, and all sorts of other debris from the river.  This is a collaborative event with the Cannon River Watershed Partnership.  Meet at the parking lot for the Lower Arboretum along Highway 19, just east of Carleton's West Gym.
