306-acre lake near Ogemaw County. The lake tops out around 34 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The rest of this page walks each species through its year, using the map's own scoring.
South Dease Lake maps at 291 acres behind 3.2 miles of shoreline. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. About 63% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 1.3 mi, about 0.6 mi across. Ogemaw County claims this one. If the bite dies, North Dease Lake is 1 mi to the north.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 10 to 34 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
