• Where to Fish on Tompson Lake

  No depth figure appears in our records, so the bank has to tell you. The productive water is a rod length or two out, not a hundred. Weed, then depth: that is the order to fish a water of this kind. Records held for Thunder Bay District cover cisco, blackfin cisco, rainbow smelt and bloater. Records at this level tell you what is in the area. The near bank of Tompson Lake is often the one people ignore.

• Seasonal Patterns

  Typical July readings run about 16°C; by January the average is down near -18°C. This is a two-season water: locked, then wide open. Look for the thaw near early May; the fishing lifts straight after. Ice usually gives way near early May, and forms again about mid November. June through September is the settled part of the year, with the shoulders busier for fish. Tompson Lake runs to its own calendar within the local pattern.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. This is a natural basin, not a dammed one. Nothing is mapped in the way of a ramp or car park within a short radius. One rod, a handful of hooks and floats, and a few small lures are enough for this water. Rules differ from one water to the next round here. A polite question at the farm gate opens more banks than anything else. The nearest alternative is Skerrett Lake, 3.5 km out. Nothing on Tompson Lake should be assumed from this page alone.
