That's kind of what I figured. In the Black Gumbo Clay of southeast Texas and Louisiana they seem to be prevalent, but where this lake is a bit further North, near Lake Livinston, there is much more sand.
I recently added over 80 Xmas tress for fish cover. It was a lot of work, but I was happily surprised at how fast the smaller fish began using it for cover.
I guess I should consider the Crawfish to be supplemental forage that I drop into a brush pile, every Spring season, for a quick protein boost before the Bass begin to spawn. Over time, surviving Crawfish may start a small colony, which would be an added benefit.
Thanks to all and now we have a good thread to search on, with all the common names for the little lobsters.
