Good response Pheasant Tail 2, quite plausible. I was conversing about this subject 3 days ago @ a local restaurant near the lake and the owner stated "the Fish Commission said someone released goldfish in the lake and they had a virus". That would be possible, but I question how the FC was aware goldfish were released and if they were aware, one would think they would prosecute for releasing non-native species. It seems unlikely they were merely observed in the lake given its' size and unlikely they just happened to roll up on the activity as it happened. Still, it would be possible, just unlikely. I wonder how many carp were eradicated???
