That area is a little deceiving. Just north of the Casino building is a dive area that is roped off. The designated anchorage area is just further out from that dive park. The depth in that area starts around 70'/80' and gets deeper rather quickly. It's surprising how quickly the island drops off. I've seen at least 3 or 4 boats drag anchor this summer and end up fouled in the dive park's ropes.
Some charts can throw you off too because the area directly adjacent to Descanso Beach (NW of the Casino Building) sometimes is listed as an anchorage area but is really filled with moorings. Also, the Avalon moorings outside of the harbor (Descanso Beach and Hamilton Cove) can get a bit bumpy and uncomfortable from all the boat wake and when the swells line up just right.
