The Crystal River near Glen Arbor in Leelanau County is one of the central features in a new documentary film to be screened on WCMU Public Television at Noon on Sunday, Oct. 2. Restoring Aquatic Ecosystems shines a light on Michigan’s first indigenous-led, multi-agency collaborative created to restore and protect the ecology of streams and rivers across the entire region. Led by the Grand Traverse Band (GTB) of Ottawa and Chippewa Indians, the Tribal Stream and Michigan Fruitbelt Collaborative includes more than a dozen nonprofit organizations and governmental agencies working together to remove blockages to the natural flow of water in Michigan’s streams and rivers—often called “the arteries of mother earth.”
