If you go all the way up around Haines point, past the Maine st waterfront to the bridges where you can see through to the tidal basin, at high tide it looks like this:



If you hug the deck, someone might be able to get through that - but that line you see on the other side is the barrier.

If you go through at low tide it looks like this:







You could possibly portage across that barrier into the tidal basin. I didn't risk it
