Garrison Lake Fishing in Frontenac County, Ontario

• Overview

  Garrison Lake sits in Frontenac County, out in Ontario. Mixed forest runs right down to the water. The water covers some 34 hectares, so pick a bank rather than trying to cover it all. There is roughly 3.2 km of shoreline here, which is a short walk end to end. It is low-lying compared with other Ontario water we list. For supplies, Sharbot Lake is 21 km out. Tweed is 41 km and Madoc 49 km. Rules here are straightforward: one set of provincial rules.

• Where to Fish on Garrison Lake

  There is no recorded depth, so work from what you can see. Where the bottom changes texture, fish gather; find that line. Read the surface for the wind lane, then fish the edge of it. Species logged across Frontenac County include pumpkinseed, bluegill, rock bass and smallmouth bass. The county figures include rivers and lakes alike. The shape of Garrison Lake decides where the fish sit.

• Seasonal Patterns

  Average temperature peaks around 20°C in July and bottoms out near -10°C in January. Winter shuts things down for a spell, then spring reopens them fast. Ice is part of the season here, ending near mid April. Averages suggest open water from about mid April through to roughly early December. The middle of summer slows a little, with dawn and dusk carrying it. That shapes the year on Garrison Lake.

• Tackle & Baits

  No access rule appears in what we hold. Records list it as a natural water body rather than an impoundment. Boats go in at Boat Launch, roughly 360 m from the water. A picnic spot sits 1.1 km from the bank. 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. Some water is controlled locally without a sign saying so. The nearest alternative is Cedar Lake, 1.6 km out. Nothing on Garrison Lake should be assumed from this page alone.
