trout

Sadly found a few resident trout / browns or ? dead in the water??? Port Dover near Tisdale Road at the Lyn River Falls. I attempted to report to MNR and due to potential water issues it was suggested to contact Environment Canada ..? Any other suggestions

I was wondering if anyone has caught fish other than Pike and bass in the ponds? I hear that crappie used to be popular but not so much anymore, and some of the ponds used to have trout in them. Any help is appreciated.
