hi
Bates to Lemieux island is the standard run to get in a surf at Remic rapids and a shuttle is usually set up cuz back getting back upstream is quite difficult.
We used to take out at Lemieux closer to the Parkway rather than the Island itself, leaving a car parked outside the access gate to the Island.
Launching from the Lemieux Island might be difficult since it could be fenced off.
As for paddling below Lemieux, well those big yellow warning signs above the falls will certainly make listening to the Blues interesting.
