They re-produce and have lived thru a drawdown to next to nothing at Silverwood. Brown trout dead, Rainbow population near to dead, had to re-establish the rainbow population, but the stripers are back without any re-introduction, not to mention LMB's (they co-exist?, incredible LMB year), wait forgot to mention the bluegill explosion this year.
They will survive no matter what.
Shad very limited at Silverwood for the last few years, this year I'm seeing balls, they will find a way....
