In our bow shooting club one guy made his bow from Osage Orange also and before retiring as a model maker we used Osage Orange for some of our clay sculpturing tools.
Before my pond filled I used lots of rock, bricks & building blocks to make rock reefs in my pond. Lots of gravel and sand for spawning bluegills areas and a large rolled up farm fencing in one pond area. Nine tires tied together in a pyramid 4-3-2 with rock in the bottom four tires and hole drilled in the tops of the lower seven tires to allow the water to escape but not in the upper two so as to keep the unit upright while sinking to the bottom.

I set them on my the frozen pond and it sank upright when the ice melted. Also rift raft rocks in another area for crayfish.
Also a couple of 4'x 4' rafts with many upright 4' stakes and then these were sunk with rocks on the rafts.
Wingnut if you raise your island above the water you may want to put some rocks or even stacked sackcreat around the earth base to keep the earth from floating outward from the base over time. Your can just lay sackcreat in the bag and it will harden on it's own and become a big rock.
