Try some bucket or pallet stake beds they work great in lakes with mud bottoms . Do a search cause we have built lots of them and made many posts . Fish love them and we use mostly free or inexpensive materails . Building supply places usually sell busted bags of concrete cheap . small saw mills give away or sell scraps cheap (works good to share fish or take them fishing ) , rocks can be gathered for free , and many places are glad for you to haul away old pallets.
