I think we have to take everything with a grain of salt and think about it.
1. Zebra mussels - when they were first dicovered they were going to be the death of the
lake. Not so cleaned itup and now there are more bait fish the Pro
Brass fishing folks say it's the best, yes the best small mouth fishing
in the country.
2. Gobies - I don't think there is enough evidence good or bad but there is talk that they
are just another form of bit fish for the larger species.
I live in Western New York and have been going to the lake since I was about 3 or 4, my wife's father purchase a cottage up in Port Colburn in the early 60's , he's in his late 80's and we talk about how the lake has changed and how there was alot of beach and now there isn't and then there is.
Alarmist, mother nature will provide and what will be will be.
