You already got an answer below, but I just wanted to add that few associations on the west shore have buoys you can rent very inexpensively if you are a home owner in those neighborhoods. Chamberlands and Tahoe Park are the two popular ones, so if you are not a member of such an HOA, and need a buoy, it is a great time to trade up. I have several clients doing it.
The HOA fees are also very reasonable. In Tahoe Park it is only 260/year (plus buoy rental).
