Onagun Lake, Ontario: Fishing Spots and Seasons

• Overview

  Onagun Lake is set in Nipissing District, Ontario. The land about it is mixed forest. The water covers some 11 hectares, so pick a bank rather than trying to cover it all. There is roughly 1.7 km of shoreline here, which is a short walk end to end. You are 65 km from Mattawa. Barrie is the closest city, 187 km away. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Onagun Lake

  No depth figure appears in our records, so the bank has to tell you. The shallow end warms first and pulls fish in ahead of the rest. A soft bed grows weed late into autumn, which keeps fish shallow. Reported across Nipissing District: smallmouth bass, cisco, yellow perch, pumpkinseed and rock bass. These are county-wide records, so not all of them will be in this water. Fish Onagun Lake to its features, not to its size.

• Seasonal Patterns

  Expect July to average close to 18°C, with January the cold end at about -13°C. The middle months are generous; the ends are demanding. Count the season from break-up, usually late April. Open water usually runs from late April until about late November. September and October fish steadily right up to the freeze. Plan around that when you fish Onagun Lake.

• Tackle & Baits

  Access status is simply unknown for this water. It formed naturally, so levels move with rainfall rather than with a gate. There is no recorded infrastructure here; expect to find your own way in. Take the rules with you rather than trusting memory. Barbless rules turn up on managed water more often than not. If the gate is shut, Three Island Lake at 1.6 km is the nearest alternative. What applies at Onagun Lake may have changed since it was mapped.
