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.
The HM for Waterfall allows players in Pokemon Ruby to ascend and descend large waterfalls. In Pokemon Ruby, this HM is obtained in the Cave of Origin before the battle with Groudon.
