There isn't one number. That's the part people don't expect.
Every homeowner I talk to about an addition, a remodel, or a new build on the water wants a single figure they can plan around. The honest answer is that your setback depends on how your specific lake is classified, and I'd rather tell you that upfront than let you design around the wrong number.
The three classifications
Minnesota's shoreland rules sort lakes into three tiers: Natural Environment, Recreational Development, and General Development. The more sensitive the water body, the more restrictive the classification, and the further back a structure has to sit. White Bear Lake and Centerville Lake both fall under General Development or Recreational Development, which puts most structure setbacks in the 50-foot range from the ordinary high water level, though your specific city or county ordinance can require more than the state floor.
The shore impact zone
Half of your structure setback is also your shore impact zone. Inside that strip, intensive vegetation clearing isn't allowed. This one catches people during a remodel more than a new build, someone wants to clear out brush for a better lake view and doesn't realize that zone is protected separately from the setback line itself.
What's exempt
Docks and other water-oriented accessory structures aren't held to the full structure setback. They still need to sit at least 10 feet off the ordinary high water level, but they're governed by a different set of rules than your house or garage.
Why this matters before you design anything
I've seen homeowners get a full set of remodel plans drawn up before checking their setback, only to find out the addition they wanted has to shrink or move. Confirming your lake's classification and your city's specific ordinance before the design phase saves real money. The state sets a floor. Your city or county can build on top of it, and often does.
If you're planning a build or addition on White Bear Lake, Centerville, Bald Eagle, or any lake in the corridor, I'm glad to help you find out exactly where your setback lands before you're paying an architect to redraw anything.
Blessings.
