Roundrock Lake, Ontario: Fishing Spots and Seasons

• Overview

  Roundrock Lake is a Thunder Bay District water, in Ontario. It sits at 487 metres above sea level. With some 14 hectares of water, there is room for a boat but no need of one. The bank runs about 2.6 km all the way round, so one visit can cover most of it. On size it sits at the modest end of our Thunder Bay District list. Supplies mean a trip to Lappe, 69 km off. The nearest city of size is Thunder Bay, 79 km away. It sits well inside its county, with no border complications.

• Where to Fish on Roundrock Lake

  No depth figure has reached our records, which makes a plummet useful. The shallow end warms first and pulls fish in ahead of the rest. A natural lake fishes on cover, and cover here means weed and timber. Across Thunder Bay District, recorded fish include cisco, blackfin cisco, rainbow smelt, bloater and shortjaw cisco. It is the county picture; the agency list is water-specific. The shape of Roundrock Lake decides where the fish sit.

• Seasonal Patterns

  Typical July readings run about 17°C; by January the average is down near -17°C. The freeze arrives properly here and holds. The lid usually sets by midwinter and gives way around early May. Open water usually runs from early May until about mid November. The first weeks of open water and the last are the ones to plan for. Plan around that when you fish Roundrock Lake.

• Tackle & Baits

  Nothing in our records says who may fish here. It formed naturally, so levels move with rainfall rather than with a gate. No made access appears within a short radius, so plan to park on a verge and walk. One rod, a handful of hooks and floats, and a few small lures are enough for this water. Where a permit is needed, the nearest town usually sells it. Some ground is open by custom rather than by right, so tread carefully. Should this one be busy, Anne Lake is 1.4 km off.
