Blue Lake is a large geothermal pond located about 16 mi (26 km) south of Wendover, Utah at 40°30′07″N 114°01′56″W / 40.50194°N 114.03222°W / 40.50194; -114.03222.

It is located on the Utah Test and Training Range, which is controlled by the United States Air Force, but the lake and its immediate surroundings are publicly accessible wetlands that are managed by the United States Bureau of Land Management (BLM).

Blue Lake's constant high-volume flow of clear springwater provides underwater visibility of up to 60 feet (18 m) at (rare) times, and year-round bottom temperatures of approximately 85 °F (29 °C).

In addition, divers have placed objects on the bottom, such as large metal sculptures of marine animals, boats, a chair and TV set, to add interest.

The tilapia criteria reflect the fact that this species was introduced to Blue Lake illegally, and it competes with the native game fish for habitat.
