Pre-event how were your various population conditions? If you had a partial die-off and still have lots of TFS including adults and are not predator crowded I would just watch for a while. With parts of the lake having plenty of O2 via aeration I would not be sure it was O2 caused. Fish will move to areas of sufficient O2 and do so often. Did you see fish crowding around the diffuser areas(boils) or surface aerators ?
