Under "File" click on "Export Water To Bitmap" this will create a sub folder in your terrains root folder called "imptexpt" .
Inside this folder you will find two files, a waterc.bmp file and a waterd.bmp file.
IF your system and video card can handle the large file size 16384 x 16384 pixels or 256megs. Open it in a graphics program
