Hey Bare,
Pointe Au Baril is my home away from home. The parents used to own a resort there, now taken over by Sturgeon Bay and run down
There are a few resorts up there. Pretty pricey though.
Have a look here: Pointe Au Baril Chamber
The main resorts are listed there. There are smaller places too, up in Bayfield, plus the Ojibway (dont know if its all private) and there are a few places for rent on Shawanaga Bay that are privately owned cottages. Or you could just camp at Stugeon Bay. Its a great park, nice and small. Jigger has also been there so PM him if you want his opinion.
As for fishing in August, depending on the time, early August (hot day and night) late August (hot only during the day) fishing is usually great. Bass really seem to turn on the last week of July/first week of August. You have Pike, bass, pickeral, and a lot of pan fish.
Its a great place to go, and if you can get out on the water, its beautiful up there.
Let me know if you want any more info and I will gladly help you out.
