The pond has just less than 9 acres in the middle that is about 10ft deep and without structure. This seems like it would be a void of sorts for fish. Would it be beneficial to start adding brushpiles and rockpiles into this large open area to promote fish use of more of the pond. If I could somehow recruit more forage or give predators another place to live I would be thrilled.

We do swim and jetski in the middle so I wouldn't want anything to stick up to within 5ft of the surface. The one exception would be under an island or floating dock that we could swim from. If I had a floating dock I wouldn't hesitate to attach something from the middle of it down into the pond for habitat.

Ideas or wasting my thoughts?
