I grew up on Cayuga and yes the fishing has changed. The bass tourneys laid waste to the bass fishery. Pressure changed the bass habits quickly. By far the most encompassing is the zebra mussels. Once the lake's food base was altered, removed, and the lake got clearer, things moved deeper. Enter the Gobi....and on and on. Oh wait, almost forgot the large heat exchange in the south end, sorry trout....Things change all the time. It's how we adapt to them that matters.
