You could try staking them to lake bottom. Hammer 8 foot stake (largest I could find) in 5 or 6 foot depth, then tie tree (artificial or natural) to it. Either let it get waterlogged & sink, or tie cinderblock to base.

Won't tip over, you know exactly where it is, and you can easily add more over time.
