I am planning on creating some underwater humps and islands in a pond that I am building later this summer. I am curious to hear what others think about...
1. How big to make each hump/island, both in terms of radius and vertical rise.
2. How far below the water level to terminate them. (I am think about 2'-3' below the water level and anticipate weeds growing on top of them. But I think that the weeds will provide cover for smaller fish, so I am OK with it.
3. Do you need to rip rap the sides, even if they are all 2'-3'+ under water?
4. I am also considering laying a log/tree off of the end of each hump that I would anchor in place. The thought is that the branches would extend down into the water and create natural looking, quality habitat underwater, with perhaps a little bit of exposed trunk that turtles could sit on or birds could alight on.
Any other "island" or "hump" ideas or advice are welcome. TIA.
