Thank you for the videos on putting a siphon in place. I was away for a few days and upon return the pond is back to normal level and the flow on the back side through the pipe looks normal. There is a slight flow separate from the pipe (bad) but it's not aggressive. I'm going to put a siphon in place today or tomorrow. I need to get below the overflow and take a look at the issue.

Does anyone have advice on a camera/light on a pole or something similar as the diagnostics on my overflow pipe could dramatically change my actions. If the breach is 20 ft in it's in a very good place to fix it. If it is 40ft in or 50 ft in (below the dam) it's a very different proposition. I imagine its much further in as that's where the pressures would be greater. The water at the surface was only 20 feet back but this is the key part I'm trying to understand. The exit of the overlflow is approx 80-100 feet from the opening in the pond. I was thinking a camera to connect to a phone on a wire or similar..
