I dont think there is much of a tide except when a low pressure system is approaching. Once while fishing from my pier on L.Winnebago I saw the lake drop about 20 in. in a hurry, this unusual occurence is called a seich and when it occures over L.Michigan the drop in water level can be drastic. Thats all I know of the subject of tides here. If you want tide tables to scan more beach, Michigan is as low as I've seen it in yrs. I just returned from the northwoods and even the lakes up there are way down. This is as good as it gets for more area to work, beats the hell out of workin them when there brim full.
