Rock Lake Fishing Guide, Renfrew County, Ontario

• Overview

  Rock Lake lies in Renfrew County, in Ontario. The surroundings are rolling bush. This is a pocket water of some 10 hectares, and every part of it is reachable from the bank. Roughly 1.3 km of bank means you can walk to a fresh area when one goes quiet. It is low-lying compared with other Ontario water we list. Deep River sits 12 km from here and is the nearest stop. Chalk River is 14 km and Petawawa 31 km. The nearest edge is a long way off, so local rules apply throughout.

• Where to Fish on Rock Lake

  Depth is unknown to us, and the shoreline is the better guide. Read the surface for the wind lane, then fish the edge of it. The productive water is a rod length or two out, not a hundred. Across Renfrew County, recorded fish include smallmouth bass, pumpkinseed, yellow perch and rock bass. Those are county-wide records, so not every one of them will be in this water. On Rock Lake the obvious spot is not always the productive one.

• Seasonal Patterns

  Average temperature peaks around 19°C in July and bottoms out near -13°C in January. Winter closes the water for a while, and the reopening is worth catching. Firm cover through the cold months, then open water from late April. The season between ice runs from about late April to late November. September and October fish steadily right up to the freeze. Keep it in mind when planning a trip to Rock Lake.

• Tackle & Baits

  The access position is unclear from public sources. It formed naturally, so levels move with rainfall rather than with a gate. Nothing built is recorded close to the bank here. A small crankbait along the drop and a worm in the thick stuff cover the bass. Where access is informal, keep it that way by behaving. Signs go up and come down, so check on the day. For a change of water, Clear Lake is 2.7 km distant. Treat Rock Lake as unsettled until someone local tells you otherwise.
