Welcome to PB posting.

For BG beds

" In Role of Male Parental Care in Survival of Larval Bluegills by Mark B. Bain and Louis A. Helfrich in Transactions of the American Fisheries Society 112: 47-52, 1983 the authors noted optimum Bluegill nest materials were exposed coarse gravel ( 8-32 mm diameter) and pebbles (32-64 mm) in nest substrate and that Bluegill removed particles smaller than 2 mm. Particles larger than 8 mm provided suitable interstitial space to accommodate bluegill larvae. Survival of larvae was directly correlated with the proportion of coarse substrate in the nest."

Rock ledge

IMO several rock piles (bottom to near surface) are better than a ledge.

Craws

Check to see what is natural (and allowed) in your area. They like rock piles and especially limestone.
