We launched out of the flooded 494 ramp during high water and it was fine. It was a bit shallow but the fishing dock area created a nice buffer from the current. Take it slow and there shouldn’t be a problem.
When we went, only about an inch of the railings were visible. Actually, they looked like parking barriers and the launch doc was completely jacked with a good sized stack of logs and debris braced up against it.
People did look at us rather funny…
