Lake MI Salmonoid anlgers,

I am wondering what my chances of success are for fishing lake Mi. I have never fished for salmon or trout on lake MI without a guide before. I have one lead core rod and down-riggers which I have used for lakers on Superior and in Canada with moderate success so I do have some experience. What do y’all think the chances are that my group and I could get a few fish in a half day of fishing this June. We would go out of Milwaukee or Port Washington.  I’d appreciate any input y’all can give me, I really want to know if this would be worth it. 

Thank you!
