ok i see no one has written so i will say yes you can catch stripers from time to time right behind the dam but not very often that i have seen. You also will have to really wait until spring to have a good shot at catching one in the river in KY. On the question with the castnet, you can only use a net in crocus creek and marrowbone creek and you have to go up past the first riffle. Also the net can only have a 1" mesh or you can get in trouble for that too. I actually had randall gibson tell me i could not even have a cast net in my boat behind the dam and i was using a dip net to get shad off the wing dam one day and he said i could get in trouble for that too but i think he was just pushing a little on that. So in Ky the spring and summer and early fall are much better for you to get a striper. Hope this helps.
