I am trying to design a forage pond that is binary - portions will have heavy structure and objects, and portions will have ZERO obstructions.
That is just what I have, but not limited to forage species. I have CC and a few LMB in there, too. It is an half-acre triangle with a 30' diameter island in one corner. I placed two aerator heads so there is an imaginary line between them that splits the pond. The line is parallel to the side opposite the island corner.
Behind the line includes the island, forage spawning structure, and other artificial or Xmas tree cover.
In front of the line, the bottom is clean for swimming. Also in front of the line are the floating dock, 'beach' and boat tie-up. The only fish habitat in front of the line is shoreline plants, the shade of the dock, and there are a couple milk crates hanging directly under it.
The pond is just 6' average depth, so anything on the bottom is a kick hazard to swimmers. If it were deeper, I might be comfortable swimming above fish cover deeper than 6', but 'teen-proofing' requires to consider an errant diver.
