CHEYENNE, Wyo. (AP) — Three federal agencies have scheduled meetings Tuesday and Wednesday on proposed changes to how they manage the Snake River headwaters and the river’s upper tributaries, plans that would close some roads and boater access points while improving other riverside facilities in Grand Teton National Park.

The changes result from the Craig Thomas Snake Headwaters Legacy Act of 2008, which protects 388 miles of the Snake headwaters and the river’s headwater tributaries in western Wyoming as officially designated wild and scenic rivers.
