Alatoona is a decent lake that has the fish that you are looking for. There is a boat ramp with some fishing areas called Kellog Creek that has a fair number of crappie around it in the spring months. The next good warming period should get them biting in that area. I have also done well close to the Victoria ramp. Do yourself a favor, and pick up a lake map at a bait store. That would help you find some places to fish, and it will give you an idea of what is close to you, etc.
