Have the Red Orb you borrowed from Mt. Pyre with you once you dive up to Sootopolis City.
A cutscene will trigger with you, Wallace, and the old man guarding the Cave's entrance.
Afterward, you are allowed to enter and catch Groudon.
Good luck!

As you know, Water Pokemon are mainly found in water. There's a lot of water in Pokemon Ruby, Sapphire, and Emerald. Once you go beyond Lilycove City, you'll enter the open ocean, and you'll find a lot of Water Pokemon there. If you had been more specific, I could have been of more help. Hope I did help, though.
