After flattening all the verts associated with the connected body of water, the problem was fixed. I have made checks using random views of all the areas where there is water and found no problems. I am confident that when I make my next detail check of the course it will be without this problem. For anybody who is not familiar with the course the image below will help to understand the area of the "connected body" is indicated in red or whatever colour it is:
As mentioned earlier I did make all verts associated with a connected body of water the same elevation when I set the initial elevations. (Even I know that static water is flat

I had checked that all the verts of the water texture in the immediate area of where I had the problem were the same elevation, but obviously all verts of the whole body of water must be the same elevation.
II certainly had the same problem on Wade Hampton, but tried to disguise the problem. With Victoria National the mass of water meant this was unfeasible, therefore I came to the experts, and Sage resolved my problem.
If there are any problems that still exist I am sure I can rely on members playing the Beta version to inform me of them.
Thanks for the reply,
