Lake Acuity (Japanese: エイチこ Eichi Lake) is a location in the region of Sinnoh. It is the home to the Legendary Pokémon, Uxie.
During the events of Pokémon Diamond, Pearl, and Platinum, Jupiter of Team Galactic captures the Legendary Pokémon living in the lake, easily defeating Barry who had tried to defend it. After Cyrus has been defeated at the Spear PillarDP/Distortion WorldPt, Uxie returns to the Acuity Cavern in the middle of the lake and can be caught there.
In Pokémon Platinum, accessing Lake Acuity and its lakefront requires using Rock Climb, which cannot be used outside of battle before earning the Icicle Badge from Candice at the Snowpoint Gym.

In the anime
The lake was mentioned by May and Zoey in Pruning a Passel of Pals!.
Ash and his friends were going to the Lake Acuity in Frozen on Their Tracks!, but due to Team Galactic's actions, the train was stopped at a fixed signal until the end of the episode.
The lake was the main setting in Pedal to the Mettle! and Evolving Strategies!, where a Full Battle between Ash and Paul took place.
In Uncrushing Defeat! a silhouette of Uxie appeared at the lake showing itself to Brock who was trying to find Berries to help Ash's Monferno.
In The Needs of the Three!, it was explained that Lake Acuity, and indeed all three of Sinnoh's lakes, are the entrances to another world where the Lake Trio lives, although they do not actually live in the lakes themselves.
During the Team Galactic finale, Cynthia's grandmother was stationed here, helping Professor Rowan with trying to keep Uxie safe.
In the manga
In the Pokémon Adventures manga
When she was little, Platinum once came here with her father but went missing for a while. She couldn't remember the incident until her father told her about the event.
After Diamond, Pearl and Platinum decide to split up in order to stop Team Galactic, Platinum heads towards Lake Acuity. She meets Maylene and Candice who accompany her to the lake. The three are not able to prevent Team Galactic from capturing Uxie in Tackling Tangrowth.
In the Pokémon Diamond and Pearl Adventure! manga
Jupiter went to Lake Acuity to capture Uxie. She battled her rival, Mitsumi, and lost.
Trivia
- At each of Sinnoh's lakes, a TM can be found containing a powerful move of a different type. Lake Acuity's TM is the Ice-type TM14 (Blizzard).
- Lake Acuity is the only lake in Sinnoh where a member of the Starly evolutionary line is not available. Noctowl, however, is available.
- Lake Acuity is the only lake in Sinnoh where Team Galactic isn't fought. Instead, Barry fights Jupiter, losing and vowing to become stronger.
- When Lake Acuity was first mentioned in the anime, it was shown to be covered in snow. However, in all subsequent appearances there was no snow present.
Name origin
Acuity means "sharpness of wit". This is fitting, as Uxie is the Knowledge Pokémon.
Eichi is from 英知 eichi, "wisdom" or "intellect".
