I haven't personally been involved with any of it other than some early work with site selection to minimize the impact on the brushpiles people have put out. There is an update on the western kentucky fisheries page with the latest details, but since I wasn't involved I don't have a lot of insight into how it went or how its going.
Regarding the concerns of lost fish habitat, I can tell you that whatever is removed is just going to be resunk outside of the small seining areas. So far it hasnt been any huge amounts of habitat. I have only personally seen the habitat removed from the sledd creek seine site and its small enough to fit on one boat. We very likely sank more habitat just this morning as part of our routine brush pile program than has been removed from all of the seining areas combined. The removal/relocation will have essentially no impact on the fishery as a whole, but I do realize that it is unfortunate for the small subset of anglers who initially placed that habitat without knowing it would eventually become a seining area.
