The DEC was aware, if there were multiple species found it likely would have triggered an investigation. It is not uncommon to have what's called a spring kill. Many other local water bodies had the same thing this year.Nice bass BTW.
Strange that no other fish species were floating. There must be crappie, perch, catfish, small bass and others in that lake, but only floating sunfish bodies? Did it happen in other years?
Doubt the DEC will investigate any time soon unless there's a connection to recent human consumption and illness.
