That's the point, guys. It couldn't even be a battle in the water; it wouldn't even be a battle. Do you really think Rathalos would even go in the water after Lagiacrus? More likely Lagiacrus is getting beaten so he flees to water, were Rathalos wouldn't follow him.

The only feasible battle place is on land (area 5 actually, as that is the only area they ever both go in), where technically Rathalos would be in the air and Lagiacrus would be grounded. Unless he's on the ground, Lagiacrus couldn't do anything more than shoot thunder balls at him. And as I said before, fireballs hurt Lagia more than thunder balls hurt Rlos.
