Diamond & Pearl Lake Acuity
Team Galactic reaches Lake Acuity first, swarming the shore to seize Uxie while Commander Jupiter blocks the ice. The spirit of knowledge sleeps in the water just out of reach.
Lake Acuity is in Sinnoh, with Acuity Lakefront to the south. In the story it comes after Snowpoint City and before Spear Pillar.

The grass ringing the lake leans Ice, with Smoochum at 40 percent and Sneasel prowling beside Solrock, Lunatone, and Ursaring. Uxie waits at the bottom at level 50 once the Galactic crisis sends you here.

Lake Acuity Guide
Uxie, the Being of Knowledge, waits in Acuity Cavern at the middle of Lake Acuity, which you reach from the Acuity Lakefront near Snowpoint City. It only becomes catchable once you beat Cyrus at Spear Pillar. Surf out to the central cave to start the battle. Uxie is Level 50 and stays put in its cavern, so there is no roaming chase like there is with Mesprit.
