Lake Cataria was a body of water on planet Betazed.

Deanna Troi proposed a holoprogram of Lake Cataria as a location for a date with Worf in 2370. (TNG episode: "All Good Things...")

In 2371, a small village was being planned on the shore of Lake Cataria, to accomodate the influx of Federation citizens relocating to the planet. These plans were presumably abandoned following the Dominion invasion of Betazed in 2374. (short story: "The Ceremony of Innocence is Drowned")

In 2379, Lwaxana Troi reserved a park near Lake Cataria for the wedding of her daughter, Counselor Deanna Troi, to Captain William T. Riker. (TNG novel: A Time for War, A Time for Peace)
