Ostrum Lake in Kenora District: How and When to Fish It

• Overview

  Look for Ostrum Lake in the Kenora District part of Ontario. The water sits 417 metres up. It runs to roughly 64 hectares — big enough to hold fish away from the bank, small enough to learn. The edge runs 4.7 km or so, easy to work in an afternoon. 30 km away sits Ignace, the nearest town. It is 235 km to Thunder Bay, the nearest city. It sits well inside its county, with no border complications.

• Where to Fish on Ostrum Lake

  Nothing in our records gives a depth for this one. A natural lake fishes on cover, and cover here means weed and timber. The productive water is a rod length or two out, not a hundred. Open biodiversity records for Kenora District list northern pike, longnose sucker, white sucker and johnny darter. The county figures include rivers and lakes alike. The shape of Ostrum Lake rewards a slow walk along one bank.

• Seasonal Patterns

  Long-term averages put July at about 18°C and January near -18°C. Cold locks it up for a good stretch each year. Once it clears, about late April, the fishing comes on quickly. Average temperatures cross freezing around late April in spring and again near mid November in autumn. Right after break-up, and again as the nights sharpen, is when to go. Ostrum Lake runs to its own calendar within the local pattern.

• Tackle & Baits

  Access is not recorded for this water. This is a natural basin, not a dammed one. Mapping records no facilities at all near this water. Pike mean a wire trace, no exceptions; big spoons and jerkbaits do the searching. Where the road in crosses private land, ask first. Barbless rules turn up on managed water more often than not. The nearest alternative is Army Lake, 1.3 km out. Where Ostrum Lake is concerned, a local answer beats a written one.
