CityDad, from my research you want papershell crawfish. They are not a burrowing type and the last thing you want is deep boreholes in your dam. You will want some rock piles for cover and breeding. Others have recommended not adding crawfish to your pond until predators are established because the crawfish can over populate and get out of hand pretty quickly. There is a wealth of knowledge on this forum from guys like snipe, Bill Cody, Quarter acre, TJ, esshup, and many others. They all have been very helpful and instrumental in helping me with my pond.
