In my experience carp can be controlled with bass. I was using a certain amount of carp for FA control and their off springs never had a chance to grow up. I know this because I could count them at feedings for over a decade.
But carp can really muddy the water. I was kayaking in a clear reservoir and paddle into a 5 acre cove that was so muddy that when I stuck my paddled into it to see how deep it was, it was only 6 inches where I thought it might be 6 feet. Every now and then I would see a carp jump, so they were thick.
Looking at your picture it would seem you have enough grass to keep the pond from becoming that muddy from run off. If you do a jar test for mud let us know. My guess is mud from carp and CC. A 50 year old pond should have weeds growing in it, so the sun is completely blocked by what ever it is.
