Big Lake Fishing in Renfrew County, Ontario

• Overview

  The Renfrew County entry here is Big Lake, in Ontario. The bank is 207 metres above sea level. With some 12 hectares of water, there is room for a boat but no need of one. About 1.6 km of bank, so nothing stays unexplored for long. By elevation it sits in the lower part of our Ontario listings. The closest town, Petawawa, is 12 km distant. Chalk River is 20 km away, with Pembroke at 24 km. It lies deep inside the county rather than near an edge.

• Where to Fish on Big Lake

  No published figure covers depth, so learn it as you fish. A soft bed grows weed late into autumn, which keeps fish shallow. Bays and points beat straight shoreline every time on water like this. Survey and observation records for Renfrew County include smallmouth bass, pumpkinseed, yellow perch and rock bass. It is the county picture; the agency list is water-specific. Big Lake responds to conditions more than to tactics.

• Seasonal Patterns

  July is the warm end of the year here, averaging about 19°C, while January sits near -13°C. Seasons are distinct, and each one fishes differently. The lid usually goes in late April, which opens the strongest weeks of the year. Averages place the thaw at late April and the freeze at early December. Fish feed hardest at the start and the close of the open season. It holds true on Big Lake more years than not.

• Tackle & Baits

  Public sources are silent on who controls the bank. 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. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Parking space is the usual limit rather than the bank itself. Where parking is tight, arriving early solves most problems. Failing this one, try Corr Lake, 2.7 km away. Confirm access to Big Lake locally before you travel.
