I was at Portland Mills last Monday, April 18th. At that time the lake was 8 ft low, the gate to the ramp was locked and there was about 75 yards of land from the creek channel (where the only water was) to the ramp. I just checked my lake elevation website and as of Thursday the lake was 5.1 ft low. I put in at the state park ramp, but did see some smaller boats putting in at the Hollandsburg ramp. If you want to go up the creek, I would strongly suggest a lake map GPS chip that shows the channel. I made it up there, but even with that ran aground once. There is still large areas of exposed earth and other areas of very, very shallow water up there.
