Doesn't matter...you'll still have the effects of being underwater.

Read above. He can't make the whole level underwater because say he makes a water plane above the city. Even if he portals it with less fog you will still be underwater and thus nothing else will change. You will still have the underwater sounds, visual effects, and gameplay effects. He can't do both underwater AND flooded unless he makes the level where you can't look outside therefore seeming like your underwater. His best chance here is to make an undersea like skybox for best result.
