Mountain Lake in Haliburton County: How and When to Fish It

• Overview

  Mountain Lake lies in Haliburton County, Ontario. The bank gives way to pine and birch. With some 17 hectares of water, there is room for a boat but no need of one. Bank access stretches around 2.0 km in total. Haliburton Village lies 21 km from the water. The nearest city of size is Barrie, 132 km away. It sits well inside the county, so one set of rules covers it.

• Where to Fish on Mountain Lake

  We hold no depth figure for this one. A soft bed grows weed late into autumn, which keeps fish shallow. Where the bottom changes texture, fish gather; find that line. Fish documented in Haliburton County include smallmouth bass, pumpkinseed, rock bass, yellow perch and lake trout. It is the county picture; the agency list is water-specific. Fish Mountain Lake where the bottom changes rather than where it looks deep.

• Seasonal Patterns

  Between January at about -11°C and July at about 18°C, the water has a wide range to work through. Cold winters and warm summers give a wide working range. Winter locks it down, and late April brings it back. Averages suggest open water from about late April through to roughly late November. September and October fish steadily right up to the freeze. Mountain Lake fishes to that pattern most years.

• Tackle & Baits

  Who may fish here is not settled in anything we hold. No dam controls it, and the level follows the season. There is no mapped parking or launch nearby, which keeps numbers down. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Some banks are open only from a marked point. Close seasons apply to some species and not others. Cockle Lake at 0.6 km is the sensible second choice. Treat access at Mountain Lake as something to verify.
