Sea through water

First a foremost, sorry for the pun.

I’m having a bit of an issue with my water material. It looks fine when it is receiving reflections (as you can see in the lower half of the image) but then when you pan down you can see the terrain below. I know about the limitations of water based reflections in UE4 but is there some sort of work around to make the water look more… infinite?

If anyone can offer some pointers on how to fix this it would be massively appreciated.

Thanks.
