O.S.A. Lake in Sudbury: How and When to Fish It

• Overview

  O.S.A. Lake is a Sudbury water, in Ontario. Around the bank it is mixed forest. At 2.94 sq km this is proper open water rather than a pond. The outline measures near 14 km, so local knowledge counts. Size puts it in the front rank of our Sudbury list. Espanola lies 36 km from the water. Further out sit Little Current (41 km) and Lively (46 km). It sits well inside its county, with no border complications.

• Where to Fish on O.S.A. Lake

  Open data we checked carries no depth for this water. A natural lake fishes on cover, and cover here means weed and timber. This is a lake, so the margins and the first drop matter most. Open biodiversity records for Sudbury list smallmouth bass, northern pike, yellow perch, Iowa darter and walleye. These are county-wide records, so not all of them will be in this water. At O.S.A. Lake the water rewards a slow, careful approach.

• Seasonal Patterns

  Average temperature peaks around 19°C in July and bottoms out near -10°C in January. A hard winter is normal, and the thaw brings a strong few weeks. Ice fishing carries the winter, and the water opens about late April. 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. On O.S.A. Lake that shapes the whole year.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. No dam controls it, and the level follows the season. A camping area sits within 400 m of here. A small crankbait along the drop and a worm in the thick stuff cover the bass. Some banks are open only from a marked point. Some water is controlled locally without a sign saying so. Teardrop Lake, 1.5 km away, makes the obvious fallback. Where O.S.A. Lake is concerned, a local answer beats a written one.
