Rim Lake in Thunder Bay District: How and When to Fish It

• Overview

  Rim Lake falls in Thunder Bay District, part of Ontario. It sits at 496 metres above sea level. At about 16 hectares, a day is enough to walk the shoreline properly. The whole outline is near 1.8 km, and most of it is walkable. On size it sits at the modest end of our Thunder Bay District list. The closest town, Nipigon, is 41 km away. Thunder Bay is the closest city, 142 km away. It sits well inside the county, so one set of rules covers it.

• Where to Fish on Rim Lake

  No chart reached our records; the first cast is your sounding. Look for the band where the shallows give up and the bottom falls away. This is a lake, so the margins and the first drop matter most. Survey and observation records for Thunder Bay District include cisco, blackfin cisco and rainbow smelt. Take it as the county picture rather than a promise for this water. The shape of Rim Lake rewards a slow walk along one bank.

• Seasonal Patterns

  Expect July to average close to 16°C, with January the cold end at about -19°C. This is a two-season water: locked, then wide open. Count on hard cover from midwinter, and open water from early May. Open water usually runs from early May until about mid November. Spring is short and heavy here; autumn is longer and steadier. It holds true on Rim Lake more years than not.

• Tackle & Baits

  Our records carry no access rule either way. No dam controls it, and the level follows the season. Access points are not mapped for this water, which suits people who like quiet. A light spinning outfit with a small box of lures and some bait covers most of what swims here. A landowner's word beats anything printed elsewhere. Barbless rules turn up on managed water more often than not. Dishpan Lake at 4 km is the sensible second choice. None of that is settled for Rim Lake in what we hold.
