Two years ago when I did initial stocking of LMB, RES, and CNBG I also dropped in 40 pounds of crawfish. For the first month or so I would see them along the banks in shallow water. But then no more sightings. Fast forward almost 2 years and while removing some leaf debris in the shallows I saw a large crawfish - a big un so much so I enjoyed watching and left the pinchers be. Then I got these two fellers. Definitely surprised me to find crawfish still around. Good stuff.
