Diversion Lake near Terrace Bay: Fishing Spots, Seasons and Access

• Overview

  Out in Thunder Bay District, Ontario, sits Diversion Lake. This is northern bush country. Surface area is around 71 hectares, which gives you real water without needing a boat. At about 12 km of edge, most people work one arm at a time. The town to know is Terrace Bay, 33 km out. For a city, Thunder Bay is 178 km off. No boundary runs near, so the local rules hold throughout.

• Where to Fish on Diversion Lake

  The records we hold are silent on depth, so plan to find it yourself. Where the bottom changes texture, fish gather; find that line. The productive water is a rod length or two out, not a hundred. Records held for Thunder Bay District cover cisco, blackfin cisco, rainbow smelt, bloater and shortjaw cisco. What holds for the county may not hold for this water. Diversion Lake fishes better once you know its edges.

• Seasonal Patterns

  Climate normals give 16°C for July and -17°C for January. The fishing year opens late and shuts early. The freeze runs deep into the year, with break-up near early May. The open-water window runs from around early May to about mid November in an average year. Fishing peaks soon after break-up and again before the cold returns. Diversion Lake runs to its own calendar within the local pattern.

• Tackle & Baits

  Ownership and access are not documented in what we hold. Records list it as a natural water body rather than an impoundment. Mapping shows no built access close by; expect to walk in from wherever you can leave the car. A light spinning outfit with a small box of lures and some bait covers most of what swims here. Rules differ from one water to the next round here. Fishing rules and camping rules are set separately here. For a change of water, Kenewabik Lake is 2.9 km distant.
