Agree on the placement to keep muskrats and beaver from tunneling. Dumptruck and excavator is the easiest way. Excavator picks rocks from bed of dumptruck, and spreads them a couple stones thick in the areas that you want covered.

They work very well for FHM spawning habitat and for crayfish habitat too.
