The only thing I can figure is with all the massive rain we got in the past 2 weeks all the new water shed brought in was oxygen deficient and with the low oxygen levels had a massive kill off, there are tens on thousands dead and the ones we seen swimming around, which there were thousands more didnt look like they had long before they reached the same fate. There were Grass Carp 50-60 pounds, big carp and buffies..Everything but the Gar, There fine!!
