A variety of human developments spanning more than 100 years have effected fish passage in a small but important Snake River tributary in Grand Teton. With support from the Foundation, Grand Teton National Park is working to restore fish movements from the Snake River to more than 20 miles of ancestral cutthroat trout spawning grounds in upper Ditch Creek.
