Welcome to both the world of fishing and the Club
I'll recommend a couple of things for you....the 1st is a map of Green Bay by Fishing Hot Spots, that shows depth, marked spots and gives you a few techniques to try too...
And this is a book of lake maps by Sportsmans Connection...and has several small lakes in your area included in it...plus info about Green Bay.
And this is an "outdoor atlas" for the area. I have one for southern Wisc...and will get this one later this year.
Green Bay is a truly diverse fishery as Bob said...and that is the main reason I'm mentioning these items to you. I own products by both companies...and they have been very useful over the years.
