Marys Lake Fishing Guide, Renfrew County, Ontario

• Overview

  Marys Lake falls in Renfrew County, part of Ontario. It lies 253 metres above sea level. With some 14 hectares of water, there is room for a boat but no need of one. There is roughly 1.8 km of shoreline here, which is a short walk end to end. For a base, Deep River sits 37 km out. It is 192 km to Gatineau, the nearest city. One jurisdiction covers this water end to end.

• Where to Fish on Marys Lake

  No depth figure has reached our records, which makes a plummet useful. Bays and points beat straight shoreline every time on water like this. Where the bottom changes texture, fish gather; find that line. Open biodiversity records for Renfrew County list smallmouth bass, pumpkinseed, yellow perch, rock bass and brook trout. What holds for the county may not hold for this water. Marys Lake gives up more to patience than to distance.

• Seasonal Patterns

  July runs about 19°C on average, January about -13°C. Cold locks it up for a good stretch each year. The lid arrives early and lasts until roughly late April. Open water usually runs from late April until about late November. The shoulder weeks of the open season are the productive ones. On Marys Lake the same rules apply, with local timing.

• Tackle & Baits

  Nothing on record says whether the bank is open or closed. No dam controls it, and the level follows the season. No built facilities appear in mapping around this water. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Rules differ from one water to the next round here. Some ground is open by custom rather than by right, so tread carefully. Owl Lake at 1.8 km is the sensible second choice. For Marys Lake, the notice at the access point is the final word.
