123-acre lake near Waseca County. The lake tops out around 5 ft. The depth data here comes from the Minnesota DNR survey of 1971, a decades-old survey (the DNR's original lake-survey map). The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Loon runs 123 acres with 2 miles of edge. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Tip to tip the water measures near 0.8 mi with a 0.4-mi widest point. You'll find it in Waseca County. For a second option, Clear lies 2 mi east.
Spring yellow perch on Loon hold shallow, usually 1 to 5 ft. Depth-wise the year is flat: 2 to 5 ft in summer, 2 to 5 ft once it turns cold. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
