Lake Acuity

9 Pokémon can be caught at Lake Acuity in Hisui.

Lake Acuity lies within the Alabaster Icelands of Hisui, the region later known as Sinnoh. Acuity Cavern, a cave at the lake's center, is the dwelling of Uxie, the Legendary guardian called the Being of Knowledge. Volo claims the lake holds seawater, though whether geography or a Pokémon is responsible remains unknown. In Diamond, Pearl, and Platinum, as well as Brilliant Diamond and Shining Pearl, Team Galactic's Jupiter seizes the resident Legendary Pokémon here.
