Big Ohlmann Lake Fishing Guide, Frontenac County, Ontario

• Overview

  This water sits in Frontenac County, Ontario. It stands 282 metres above sea level. It runs to roughly 32 hectares — big enough to hold fish away from the bank, small enough to learn. The bank runs about 3.4 km all the way round, so one visit can cover most of it. The closest town, Sharbot Lake, is 40 km away. It is 101 km to Kingston, the nearest city. Rules here are straightforward: one set of provincial rules.

• Where to Fish on Big Ohlmann Lake

  No chart reached our records; the first cast is your sounding. Still water like this holds fish on the edges rather than out in the open. A natural lake fishes on cover, and cover here means weed and timber. Records held for Frontenac County cover pumpkinseed, bluegill, rock bass and smallmouth bass. These are county-wide records, so not all of them will be in this water. Take Big Ohlmann Lake a stretch at a time.

• Seasonal Patterns

  Climate normals give 19°C for July and -12°C for January. A full turn of seasons, with the strongest sport on either side of summer. The lid arrives early and lasts until roughly late April. Break-up sits around late April on average, with the water closing again about early December. Look to early summer and the first cool weeks of autumn. Time your trip to Big Ohlmann Lake by conditions rather than dates.

• Tackle & Baits

  Nothing in our records says who may fish here. It formed naturally, so levels move with rainfall rather than with a gate. Public mapping records no formal access here, so plan for a walk and soft ground. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Look for a notice board at the entrance. A polite question at the farm gate opens more banks than anything else. Lucky Lake at 1.1 km is the sensible second choice. Ask locally about Big Ohlmann Lake if anything is unclear.
