The Great Spring River Cleanup

Become a volunteer and make a difference. Join us at the Mammoth Spring State Park Office and Welcome Center as we set off in canoes to help do our part to clean up one of North Central Arkansas' most premier trout fishing rivers. We'll put in at Dam #3 and float down to Many Islands Campground. The event is free to the public but requires reservations. Please call the state park to participate at (870) 625-7364.
