Buddy, they've got 6 more feet to drain out of it before it even gets to Summer Pool (12' if they try and bring it back to Winter pool).
My advice on where to launch would depend on where you intend to fish. That being said .... I've almost always launched at the Alfrey ramp, and a few times at the Scott Creek Marina ramp. For Spring spawn Crappie fishing, I've mostly fished in the back end of Cassidy Ford Hollow .... and along the rock cliff bank between there and Shrout Hollow. But, that was eons ago, long before the KDFWR put out all those fish attractors. ( https://www.google.com/maps/d/viewer...604999997&z=13 )
There is no size limit on Crappie at Cave Run Lake, but the state-wide creel limit is now 20/person/day. And there are no fish cleaning stations that I know of. COE Ramp fees are $3/day (or so the website says) but could be higher (like the $5/day fee at Green River Lake).
That's about all I can tell ya, as I haven't been there but once (Fall) in the last 20yrs or so. You might get some more updated info from Littlejohn, as I believe he fishes there now & then.
