Acorn Lake Fishing Guide, Renfrew County, Ontario

• Overview

  You will find Acorn Lake in Renfrew County, Ontario. It sits at 211 metres above sea level. It measures about 14 hectares, which is a comfortable size for bank fishing. Roughly 1.6 km of bank means you can walk to a fresh area when one goes quiet. By elevation it sits in the lower part of our Ontario listings. The town to know is Petawawa, 34 km out. Chalk River is 38 km and Pembroke 41 km. The nearest edge is a long way off, so local rules apply throughout.

• Where to Fish on Acorn Lake

  No depth figure appears in our records, so the bank has to tell you. The shallow end warms first and pulls fish in ahead of the rest. On a natural lake the weed line and the shelf beyond it do the work. Across Renfrew County, recorded fish include smallmouth bass, pumpkinseed, yellow perch and rock bass. Records at this level tell you what is in the area. The shape of Acorn Lake decides where the fish sit.

• Seasonal Patterns

  Averages here run 19°C at the top of summer and -13°C at the bottom of winter. A solid cap is the normal state through winter. The lid usually goes in late April, which opens the strongest weeks of the year. From about late April to around early December, expect open water on the long-run figures. June through September is the settled part of the year, with the shoulders busier for fish. Acorn Lake runs to its own calendar within the local pattern.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. It formed naturally, so levels move with rainfall rather than with a gate. Formal access is not mapped, so the last stretch is likely on foot. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Season dates differ by species, so read the table. Close seasons apply to some species and not others. If the gate is shut, Supply Lake at 1.1 km is the nearest alternative. Nothing on Acorn Lake should be assumed from this page alone.
