Fishing Collver Lake in Thunder Bay District, Ontario

• Overview

  Thunder Bay District in Ontario is where Collver Lake sits. The bank gives way to northern bush. The water covers around 1.32 sq km, which puts most of it out of reach from the bank. With 13 km or so of shoreline, boat anglers cover ground the bank cannot. Nearest place of any size is Greenstone, 142 km away. After that come Geraldton at 147 km and Longlac at 154 km. No boundary runs near, so the local rules hold throughout.

• Tackle & Baits

  We hold no note on access for this one. Records list it as a natural water body rather than an impoundment. There is no mapped parking or launch close by, which usually means walking in. Keep the gear simple: light line, small hooks, split shot and a couple of proven lures. Read any posted signs at the access point rather than assuming. Barbless rules turn up on managed water more often than not. Box Lake sits 5.9 km off and takes the overflow. The position on Collver Lake is worth confirming on the day.
