Kibo Lake was a lake on Ord Cestus. It was near the Kibo Geothermal Station and west of the Zantay Hills. It was located on Kibo Plateau. Kibo Lake was a 50-kilometer-wide volcanic crater, the fourth largest on Cestus. Near the bottom of the lake were active volcanic vents, which allowed the lake to be used as a geothermal power source. Cestus Penitentiary was located near (and under) the lake.
