Visitors are drawn to Yellowstone National Park’s Lake Hotel and the surrounding area for its expansive views, sweeping shoreline and historic structures. Spawning Yellowstone cutthroat trout use the streams emptying into Yellowstone Lake, and the fish attract grizzly bears. Figuring out how to maintain and update developed facilities while preserving those natural attractions is the goal of a draft comprehensive long-range plan for Fishing Bridge, the Lake area and Bridge Bay released this month by the National Park Service.
