Current, water temp and therefore probably oxygen content from deeper water levels rolling up from mid-lake change during an East wind event. The only tried and true tactic this time of year is if I HAVE to go fishing I will fish the Niagara Bar because the river negates the aforementioned changes to the water. Water temp is stabilized and usually warmer water from the Niagara, O2 levels are better because of the high O2 water from Niagara falls and there is always current to keep fish active (H20 across gills). Add the structure of the drop off, shallow and deep water nearby and .....there you have it. Expect more neutral fish so more spoons than flashers, spread out in all zones. Expect more lost fish due to fish being less committal or neutral resulting in more nipping at lures as opposed to slamming them and getting hooks buried in the corner of the mouth. You are as likely to catch a fish on a surface line as you are on the bottom so flood the system but keep stuff spread out. (talking out my arse is fun).
