Fishmaster,
I have fished LBDN for over 40 years, and have been a professional guide out there for the past 15 years. Your statement about no observable decline in fishing in Little Bay de Noc is actually laughable.
Look at the huge decline in boats and fishermen on the Bay the past 5-7 years. Why the Bayshore parking lot normally has overflow trailers out on the road for a half mile! The lot hasn't even been filled this year... None of the launches...Esky or the Yacht Club have hardly any trailers there at all. Ice fishing was the worst in years! The annual Perch tournament had a total of 12 Perch caught.
I have talked to dozens of anglers at the launches that are getting skunked after all day on the water...these guys have fished the North end for decades.
Several other Guides I talked say the same thing...less fish and 70-80% of the catch of Walleyes are under sized.

If you indeed are consistently doing that well I tip my hat to you... You are the only one I know that is...
