Johnston Lake Fishing Guide, Renfrew County, Ontario

• Overview

  The Renfrew County end of Ontario holds Johnston Lake. The surface lies 224 metres up. Around 42 hectares of surface means several distinct areas to work. The edge runs 3.4 km or so, easy to work in an afternoon. Size puts it in the front rank of our Renfrew County list. Chalk River at 28 km is the nearest place to stop. Deep River follows at 32 km, then Petawawa at 36 km. The nearest boundary is well away, so one set of rules covers the water.

• Where to Fish on Johnston Lake

  There is no published depth for this one, so start shallow and work out. Where the bottom changes texture, fish gather; find that line. The productive water is a rod length or two out, not a hundred. Public occurrence data for Renfrew County names smallmouth bass, pumpkinseed, yellow perch and rock bass. Species recorded across the county may be limited to a few waters. On Johnston Lake the quiet end is the one worth the extra effort.

• Seasonal Patterns

  On the long-term average, July reads 19°C and January reads -13°C. The year runs cold to warm and back, with clear transitions. Firm cover through the cold months, then open water from late April. Average temperatures cross freezing around late April in spring and again near late November in autumn. The middle of summer slows a little, with dawn and dusk carrying it. Anyone fishing Johnston Lake regularly works to that calendar.

• Tackle & Baits

  Public data does not answer the access question here. Records list it as a natural water body rather than an impoundment. There is a campsite 150 m from the water. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Ask in the nearest town if you are unsure. Keep proof of licence with you rather than in the car. If the gate is shut, Berm Lake at 1 km is the nearest alternative. Nothing here settles the position at Johnston Lake for certain.
