Yellowstone Lake

Yellowstone Lake: access and conditions

On the map, Yellowstone Lake is centered near 44.4667, -110.3667. Surface elevation is about 7,733 feet. It reaches roughly 384 feet at its deepest.

For a lake this size, the park office is the fastest way to learn how the water sits today. Yellowstone Lake has no public water level gauge that we can read, so there is no level chart here. An invented number would be worse than none.

Around Yellowstone Lake this guide maps 3 named swimming spots. Among them are Lake Yellowstone Hotel and Cabins, Yellowstone National Park and Old Faithful Inn. These come from Recreation.gov (RIDB). Unless the operating agency says otherwise, treat these as unsupervised swimming.

Nearby water includes Jackson Lake (Wyoming, 42 mi), Island Park Reservoir (Idaho, 50 mi) and Henrys Lake (Idaho, 53 mi). In all, 19 lakes in Wyoming are covered here.

No public sensor reports water temperature at Yellowstone Lake, so the panel shows air temperature and wind. Algae blooms are seasonal and local: look for posted signs at the ramp or park entrance. Most Wyoming day-use areas open for the summer season and close outside it.
