Need help with custom water

I'm trying to use a custom water model (link here), but I don't know how to raise it in the editor so that it is above the ground, like in the picture. I created a doodad and gave it a Circle of Power Pathing Texture, just like the post says. The post says you can raise the Z-axis for doodads, but there is no "Z-axis" property in the Object Editor for doodads at all! I'm probably going about this in the wrong way. All I want is to use this model! Please help!
