So I assume it creates one automatically. An HDR reflection of the environment around the water to add to the water as a cubemap to reflect the environment realistically without using dynamic mirroring, that is.
I think it does that just for image based lighting when doing the photon mapping. If you can find the cubemap bitmap tags anywhere however, its possible you could try to use them.
