We went to that beach a few years ago. There were definitely people on it, and I don't recall seeing signs that said we couldn't be out there. There's even a road "Oak Tree Ln" that goes out there. On a side note, there's a channel marker on the peninsula of that beach. From afar, it looks like an average channel marker. But up close, it's actually 2 kegs welded together. Gotta love it.
