Lake Mendota sits at roughly 9,781 acres with a maximum depth of about 83 feet, which is why I would look at one section at a time instead of the whole map. Lake Mendota is the largest and northernmost lake in Madison's Yahara chain, and generations of research at UW-Madison have made it one of the most intensively studied lakes in the world. If I only had one day on Lake Mendota, I would make one part of the lake my whole world for the first few hours.

Start with a short rotation through accessible bank cover, vegetation, and nearby deeper water. Give each spot a few deliberate casts before moving on.
Fish in the current inventory
For Lake Mendota, the fish list currently includes Black Crappie, Bluegill, Channel Catfish, Lake Sturgeon, Largemouth Bass, Muskellunge, Northern Pike, and Pumpkinseed, plus 3 more; which keeps me focused on weeds, wood, rock, or docks for bass and points, breaks, and wind-pushed edges for walleye, and see what actually shows up before changing directions.
A no-nonsense way to start
If I were taking a friend to Lake Mendota, I would make the day about finding one repeatable clue instead of collecting waypoints, and I would make sure the current Wisconsin fishing regulations do not add a special rule for this water.
