I was there Saturday morning early. I was headed to Beavertail but the road was closed due to a downed power line so I went to Wetherill.
Your right, very crowded as usual. I entered by the cove on the side and swam up the bay (freediving as I traveled) to the first island in the Dumplings, circled it, then headed back. Saw almost no fish (1 striped bass, 1 small tautog) except the ubiquitous cunner. Fought a moderate current on the way out then on the return the current had shifted and I had to swim against a weak current again. I'll never understand the currents in Narragansett Bay, they always seem to be going in the opposite direction I would predict from the tides.
