My pond is 5 feet deep with straight walls and no shelves and it definitely keeps the fish safe from the predators. I once witnessed a Heron try and come in for a landing and my 95 pound German Shepherd put the run on it. I live in a rural area with lots of predatory animals living nearby and have never lost a fish to predators. I think this is due to having dogs patrolling the yard and the fact that my pond is so deep.
