Like a I said, I went out today...Well the very worse scenario happened...They "Blue Stoned" the lake yesterday and the amount of dead fish (95% shad) was incredible!...I'm so pissed as are the folks that run the lake...This was the best spring in a long time and these jack wagons come in here and are effectively killing the lake.
I did not see any dead bass and only a couple small bluegill and crappie...Keeping my fingers crossed that the lake is deep enough this year so not do as much damage as they did 3 years ago....When every kind of fish were dead, including lot of 5-10 lb bass.
Will copper sulfate (Blue stone) kill fish?....National Pesticide Information center
"Studies with several aquatic species have found copper to be highly to very highly toxic to fish and aquatic life. Trout, koi and juvenile fish of several species are known to be particularly sensitive to copper. Fish kills have been reported after copper sulfate applications for algae control in ponds and lakes".
