I don't think so Steve. I'm not sure but believe it was somehow connected with the steam plant rather than the lock/dam. It's below the dam in between some of those big round barge docks. The post before yours has some pics of it many years ago, but I believe it is the same place. I actually have not seen it spew out like the in the photo, but have seen it spewing hot water and it's very loud when doing so. We used to fish around it in winter/early spring when the water was real cold, and the hot water coming in from the "blow hole" or "honey hole" as some call it, would stack up fish in that warmer water. I was just wondering if it was still "spewing out" hot water like it used to do and if anyone had been having any luck fishing around it??
