Sounds like the Lake s getting sketchy with the warmup.
I would highly recommend looking into guides for the Lower Niagara river of you may be heading to Buffalo. That lower river has some monster fish in it. Big steelhead, browns, and lots of big Lake trout. Most guides up there are around 180.00 a day, plus tip. They fish from boats and drift the shorelines. Sometimes they will head out to the mouth of the lake, ( ontario ). I have used Frank Cambell a few times and highly recommend him.
