Two or three years ago I was fishing for perch south of Kellys and the water was so stained that boats going by created green wakes. The algae seemed to only be at the surface since only the foot or so of anchor line at the surface was stained. The fish were down on the bottom and didn't seem affected. The were biting ok. I just hosed them off later and then cleaned them as usual. They were fine on the table. Now if it gets as bad as they say it might, maybe it will affect the fish and they will move east. I don't know. we'll find out soon.
