Just my own opinion about what is happening to the bay at the moment which may or may not be the case. The water has been very clean lately and snapper tend to be shy in shallow and head for deeper water. Because of the clear water conditions the sunlight is able to better penetrate the shallow reefs providing better growing conditions for snot weed. There is certainly a lot of it about at the moment which may be another reason for the fish to move out deeper. It's just a theory. Judging by the apparent lack of decent bay reports at the moment I don't think you're alone.
