Duff Lake Fishing near Deep River, Ontario

• Overview

  The Renfrew County end of Ontario holds Duff Lake. Elevation runs to 208 metres. At roughly 9 hectares, the whole thing is within casting reach of a single walk. It lies lower than most water we list in Ontario. Supplies mean a trip to Deep River, 17 km off. Gatineau is the closest city, 167 km away. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Duff Lake

  Nothing we hold settles how deep this runs. Look for the band where the shallows give up and the bottom falls away. Where the bottom changes texture, fish gather; find that line. Species logged across Renfrew County include smallmouth bass, pumpkinseed, yellow perch, rock bass and brook trout. Those are county-wide records, so not every one of them will be in this water. Take Duff Lake a stretch at a time.

• Seasonal Patterns

  Between January at about -13°C and July at about 19°C, the water has a wide range to work through. The middle months are generous; the ends are demanding. Firm cover through the cold months, then open water from late April. Climate averages put the opening at about late April and the closing near late November. Spring is short and heavy here; autumn is longer and steadier. It holds true on Duff Lake more years than not.

• Tackle & Baits

  No public source sets out the position on this bank. Mapping records no facilities at all near this water. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Read any posted signs at the access point rather than assuming. Where the way in crosses private ground, ask first. If the gate is shut, Louie Lake at 2.9 km is the nearest alternative. Ask locally about Duff Lake if anything is unclear.
