The water level in that region has dropped significantly, almost 3 feet I believe, from where it was last year. Therefore prepare yourself for not a ton of productivity. The water temperatures all depend on the weather which I believe is supposed to cool down in a couple of days.
I have been fishing there for a number of years and so long as you get an early start to the day you will catch fish. Probably in farther out then where you normally fish due to the low water levels. Try areas such as restouille bay, eagles island, and try trolling at night and casting in the morning right outside of sturgeon bay which is quite close to wolseley bay. Those places always produce fish ranging from bass, muskie and pike.
Hope that helps
