• Where to Fish on Topnot Lake

  Depth is not on record here, which means reading the ground instead. Bays and points beat straight shoreline every time on water like this. A soft bed grows weed late into autumn, which keeps fish shallow. Species logged across Thunder Bay District include cisco, blackfin cisco and rainbow smelt. Those are county-wide records, so not every one of them will be in this water. Topnot Lake gives up more to patience than to distance.

• Seasonal Patterns

  The range across the year is -18°C to 16°C. Water stays cold even at the height of the year. The lid usually goes in early May, which opens the strongest weeks of the year. Averages place the thaw at early May and the freeze at mid November. June through September is the settled part of the year, with the shoulders busier for fish. On Topnot Lake the same rules apply, with local timing.

• Tackle & Baits

  Public data does not answer the access question here. Records list it as a natural water body rather than an impoundment. We find no slipway, car park or made path within a short radius, so treat access as rough. Keep the gear simple: light line, small hooks, split shot and a couple of proven lures. Ask in the nearest town if you are unsure. Some ground is open by custom rather than by right, so tread carefully. Twice Lake sits 1.8 km off and takes the overflow. Confirm before you fish Topnot Lake.
