If you plan on coming up over the next few days, do bring some rubber boots, some TALL rubber boots.
See pics below taken on Mon May 8th in the afternoon. The first is the utility dock that shows how high the water is in relation to the parking lot. The second pic shows the ramp for "C" dock is pretty much submerged. Ditto for the third pic near the barge dock, no, you aren't remembering wrong, there IS a concrete pad to the left of that yellow post toward the lake by a few feet.
