Rock Lake near Pembroke: Fishing Spots, Seasons and Access

• Overview

  Rock Lake lies within the bounds of Renfrew County, Ontario. The country here is mixed forest. Roughly 14 hectares: a morning covers one end, an afternoon the other. A shoreline of some 2.5 km keeps the choices simple. By elevation it sits in the lower part of our Ontario listings. You are 21 km from Pembroke. Further out sit Petawawa (23 km) and Eganville (24 km). Rules here are straightforward: one set of provincial rules.

• Where to Fish on Rock Lake

  Depth is unmeasured here, so let the shoreline guide you. A natural lake fishes on cover, and cover here means weed and timber. Where the bottom changes texture, fish gather; find that line. County-wide records name smallmouth bass, pumpkinseed, yellow perch and rock bass. County records show the wider picture rather than this one place. Work Rock Lake in sections rather than trying to cover it.

• Seasonal Patterns

  The range across the year is -13°C to 19°C. The freeze arrives properly here and holds. Expect a solid lid for months and a thaw around late April. Averages place the thaw at late April and the freeze at early December. September and October fish steadily right up to the freeze. At Rock Lake the season follows that pattern closely.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. This is a natural basin, not a dammed one. Access is unmapped, which usually means a farm track and a walk. A small crankbait along the drop and a worm in the thick stuff cover the bass. Parking is often the real limit rather than the bank itself. Rules for boats are stricter than rules for the bank in many places. If the gate is shut, Teapot Lake at 0.9 km is the nearest alternative. Nothing here settles the position at Rock Lake for certain.
