I’m not sure about Kentucky but in Tennessee it is illegal to release baitfish into a lake. Even if that baitfish species is already in the lake, you may inadvertently be releasing microscopic organisms, parasites, diseases or viruses into the waters. You can also do this just by draining your bait tank! That’s why it is not recommended to transport live fish from one body of water to another. Catch your bait from the body of water you are fishing. Dry out you bilge and bait tank between trips to other bodies of water.
