Red Rock Lake in Renfrew County: How and When to Fish It

• Overview

  Look for Red Rock Lake in the Renfrew County part of Ontario. It sits in rolling bush. Roughly 28 hectares: a morning covers one end, an afternoon the other. There is roughly 4.2 km of shoreline here, which is a short walk end to end. It lies lower than most water we list in Ontario. Pembroke is the closest place, 20 km off. Eganville is 22 km away, with Petawawa at 23 km. This one is safely inside the county line.

• Where to Fish on Red Rock Lake

  Depth is unmeasured here, so let the shoreline guide you. The shallow end warms first and pulls fish in ahead of the rest. Read the surface for the wind lane, then fish the edge of it. Species logged across Renfrew County include smallmouth bass, pumpkinseed, yellow perch and rock bass. The list covers the county rather than this water alone, so treat it as a guide. Anyone new to Red Rock Lake should walk it once before setting up.

• Seasonal Patterns

  Expect July near 19°C and January near -13°C on the long-run figures. A hard winter is normal, and the thaw brings a strong few weeks. Ice-out usually falls in late April, and the weeks after it fish hardest. The open-water window runs from around late April to about early December in an average year. June through September is the settled part of the year, with the shoulders busier for fish. Red Rock Lake fishes to that pattern most years.

• Tackle & Baits

  Ownership and access are not documented in what we hold. Records list it as a natural water body rather than an impoundment. No made access is recorded, so a short walk in is the likely arrangement. A small crankbait along the drop and a worm in the thick stuff cover the bass. Local rules can differ across the county line, so check where you stand. Fishing rules and camping rules are set separately here. Long Lake, 1 km away, makes the obvious fallback. What applies at Red Rock Lake may have changed since it was mapped.
