Cavern Lake Fishing Guide, Thunder Bay District, Ontario

• Overview

  Within Thunder Bay District, Ontario, you have Cavern Lake. Height above sea level is 301 metres. With some 23 hectares of water, there is room for a boat but no need of one. There is roughly 5.0 km of bank, more than one visit can cover properly. Some 36 km away sits Nipigon, the nearest settlement. Thunder Bay sits 66 km out, and it is the nearest city worth the name. Rules here are straightforward: one set of provincial rules.

• Where to Fish on Cavern Lake

  The records we hold are silent on depth, so plan to find it yourself. Weed, then depth: that is the order to fish a water of this kind. A natural lake fishes on cover, and cover here means weed and timber. Reported across Thunder Bay District: cisco, blackfin cisco, rainbow smelt and bloater. What holds for the county may not hold for this water. The shape of Cavern Lake decides where the fish sit.

• Seasonal Patterns

  Temperature averages peak at 17°C in July and bottom out at -16°C in January. This far north the hard season runs and runs. The open season starts with the thaw, near enough late April. Averages suggest open water from about late April through to roughly mid November. June through September is the settled part of the year, with the shoulders busier for fish. Plan any trip to Cavern Lake around it.

• Tackle & Baits

  Whether the bank is open is not something our records settle. Records list it as a natural water body rather than an impoundment. There is no recorded infrastructure here; expect to find your own way in. One rod, a handful of hooks and floats, and a few small lures are enough for this water. Rules for this water may differ from the county norm. Access can change hands, so last year's answer may not hold. The nearest alternative is Lost Lake, 1.3 km out.
