Watched a video online that I liked on this topic. Modeled some of our habitat off of the suggestions in the video. I think what you are asking about is simple vs complex habitat and my understanding is:

Simple habitat will provide the fish some cover and ambush opportunities but really not protection from predation due to the larger gaps in it.

Complex habitat on the other hand has much tighter limbs and overlaps and does provide more protection from predation as a result.

As far as where to put it. We used our spawning beds as a prime spot for complex pieces because we wanted to get our baby fish a chance to grow a bit before they were eaten. Think about where your babies go after the spawn....this can vary based on the species.

With the simple habitat our first sites were anyplace there was an abrupt depth change (enhancement of the edge) or anyplace there was a change in the bottom (gravel bed vs mud/clay). Off a point or flat would likely be a good location as well. After we got those set, we moved on to sites adjacent to complex habitat. The goal was to give our predators an ambush location for those babies that had grown.

Lastly, our pond is not nearly as deep as yours but we did set some habitat in the deep zones of the pond. Our thought here wasn't so much for the summer months but more for winter. We have two deep pools and they were decorated with a little with of complex but mostly simple. Fish feed less in the winter and we want to make sure our predators get a chance to eat without missing to many meals.

200 acres of water. 90% of the fish in 10% of the water. The beauty here is you get the choose the 10% you really want to have them in or relate to the most. Sounds like one heck of a fun project.
