Jim,
After what has happened at Dale Hollow, I would have rather this didn't happen at all, especially on Barren. I know that there are still smallmouth in Dale, but it ruined the lake for a while. I say this thinking that the algae bloom on Dale Hollow was a precursor to a significant fish kill.
That said, for whatever reason, the largemouth seemed to have come out of hiding, based on the reports that I have seen.
