Craw dad's would need rock piles for cover. Add rock sizes from 4" to 6" and at least 2 layers thick around the bank, the more bank coverage the better and to depths of at least a foot or so. These rocks will give them a place to hide. Keep in mind...Crawdads can muddy the water and can also reduce plant populations, so think about the timing at which you introduce them. You'll want plants in the pond first, before the crawdads. Your rocks will reduce the available space for plants so don't over do the rocks. Crawdads typically hatch their eggs in the spring, only hatch once a year, so putting a few in the pond in the spring that have eggs under their tail will boost the population....gotta jump to plane mode. More later.
