Could you run your cold water ground wire that is a #4 wire to an 8' ground rod and then run a #4 wire from the ground rod to your 200 amp residential panel or does the CWG wire need to run directly to the panel ? Thank you.
 
Thats good to know. So would this require the use of 2 ground rod clamps, 1 for the CWG wire and a 2nd for the wire running from the rod to the panel, that is if you dont run 1 wire unbroken through 1 ground rod clamp. Plus Im guessing that if I had a 200 amp panel and used a #6 from the panel to the rod and a #4 to the CWG then I could not land the CWG on the rod?

That would depend on the listing of the clamp. Two wires or one.

The CWG would need a full sized GEC all the way to it - whether that GEC made a pit stop at a ground rod along the way or not.

Also, one thing to bear in mind in this configuration...

service -> ground rod -> water pipe -> Ufer

The conductor from service to ground rod is a GEC. The conductors connecting the ground rod to the water pipe, and the water pipe to a Ufer, and so on, anything that doesn't actually connect directly to the service, is a "bonding jumper", not a "grounding electrode conductor".
 
Here's a graphic:
