• Where to Fish on Upper Mazinaw Lake

  No figure exists for depth, so let the water show you. A natural lake fishes on cover, and cover here means weed and timber. A soft bed grows weed late into autumn, which keeps fish shallow. Survey and observation records for Frontenac County include pumpkinseed, bluegill, rock bass, smallmouth bass and yellow perch. County data is a starting point rather than a guarantee. On Upper Mazinaw Lake the obvious spot is not always the productive one.

• Seasonal Patterns

  The year swings from about -11°C in January to roughly 19°C in July. Expect a real winter and a strong spring after it. Hard water holds through the cold months, breaking up near late April.
