Anything below a certain height is water (sea level)

Put your water plane here, and use

Always--------(Python)

I would use a single object that tracks all dynamic objects world position, and if it goes below a depth, set a bool to true in the object.

Have each object have local logic or python that decides what to do with the info
Ie float, swim state etc.

That is diving rather than swimming.

Swimming ~ walk motion with other animation. You need to consider that your character is intersecting the water surface (ground).

Diving ~ fly motion. You might want to add some sort of buoyancy forces dependent on the distance to the water surface. You should at least counter the gravity.

Does this push you into a direction you can work with?
