Introduction to the Game By Capt. John King June is the month that can offer the most exciting fishing you've ever experienced, this it the time for the offshore surface fishery to shine. Doubles and triples of sky rocketing, mint silver Steelhead can be the rule, rather than the exception once you've located the proper set of circumstances. When Lake Michigan develops vertical thermobars, or sharp temperature breaks , it's creating natural fish attracting conditions or barriers that act like fences to contain the fish in concentrated areas. Pollen, debris and bugs all mean food to the fish.
Water density comes into play, because the warm and colder waters resist mixing.
Current rips can and will form if you're on a good break and you'll see the water moving forming pockets and slack pools. Scum line is a name you've probably heard before, although finding actual scum lines is more a matter of luck than science. Scum lines generally contain large amounts of pollen, that are a great minnow food source. What you will be finding are, sharp differences in the temperatures. Keep in mind the current and the wind keep waters constantly on the move.
