There probably are hundreds of videos about traveling the Erie Canal,
the Great Lakes and the St. Lawrence Seaway. I've watched more than a
few. This one, on the locks, was pretty good:
That video does a good job of showing what it's like to enter lock 17
at Little Falls. You enter under a vertical lift gate that looks like
it is way too low, and it feels like entering a cave built into the
side of a hill. After you exit the lock you are running along a
channel on the side of the hill, looking down into the town below on
the north side. Interesting perspective from a boat where you rarely
look down at anything except water.
With just two of us managing the boat there is unfortunately no time
for photography.
Pretty cool, interesting trip you're taking. We've transited the Pinopolis lock several times on our trips down to Charleston. It drops 75 feet from Lake Moultrie down to the Cooper River. It's pretty awe inspiring to be down at river level and look up at those doors holding a lake behind them!
