Rock Lake Fishing in Renfrew County, Ontario

• Overview

  Renfrew County, Ontario, is where Rock Lake sits. The bank gives way to mixed forest. This is a pocket water of some 6 hectares, and every part of it is reachable from the bank. The closest town, Eganville, is 24 km away. For a city, Nepean is 102 km off. Neighbouring water: Louies Lake at about 1.2 km, Cameron Lake within 1.2 km, Upper Twin Lake at about 1.4 km, Little Pine Lake within 1.6 km and Lower Twin Lake at about 1.7 km. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Rock Lake

  Open data we checked carries no depth for this water. Where the bottom changes texture, fish gather; find that line. Still water like this holds fish on the edges rather than out in the open. Renfrew County records list smallmouth bass, pumpkinseed and yellow perch among the fish reported. Records at this level tell you what is in the area. Rock Lake repays a walk before the first cast.

• Seasonal Patterns

  July is the warm end of the year here, averaging about 18°C, while January sits near -12°C. Winter shuts the surface down for months. After late April the shallows warm and the fish move up. Expect the water usable from around late April until roughly early December. Right after break-up, and again as the nights sharpen, is when to go. Plan any trip to Rock Lake around it.

• Tackle & Baits

  Access status is simply unknown for this water. Access is unmapped, which usually means a farm track and a walk. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Some banks are open only from a marked point. A polite question at the farm gate opens more banks than anything else. If the gate is shut, Louies Lake at 1.2 km is the nearest alternative. Check the position on Rock Lake before loading the car.
