Mayhew Lake Fishing Guide, Renfrew County, Ontario

• Overview

  The Renfrew County end of Ontario holds Mayhew Lake. Beyond the shoreline you have mixed forest. With some 19 hectares of water, there is room for a boat but no need of one. The bank runs about 2.4 km all the way round, so one visit can cover most of it. It is low-lying compared with other Ontario water we list. Head to Chalk River, 9.7 km away, for anything you forgot. Gatineau is the closest city, 156 km away. It sits well inside its county, with no border complications.

• Where to Fish on Mayhew Lake

  Our records carry no depth, so judge it from the bank. 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. Across Renfrew County, recorded fish include smallmouth bass, pumpkinseed and yellow perch. Those are county-wide records, so not every one of them will be in this water. Fish Mayhew Lake to its features, not to its size.

• Seasonal Patterns

  Expect July to average close to 19°C, with January the cold end at about -13°C. The season turns properly here, and fish follow it closely. Count the season from break-up, usually late April. Average temperatures cross freezing around late April in spring and again near early December in autumn. June through September is the settled part of the year, with the shoulders busier for fish. Expect Mayhew Lake to follow that timing.

• Tackle & Baits

  Access status is simply unknown for this water. No dam controls it, and the level follows the season. No made access is recorded, so a short walk in is the likely arrangement. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Check whether a boat is allowed before you tow one. Check whether bait restrictions apply before you buy any. Should this one be busy, Second Egan Lake is 1.3 km off. What applies at Mayhew Lake may have changed since it was mapped.
