Clamshell Lake Fishing Guide, Nipissing District, Ontario

• Overview

  Nipissing District, Ontario, is where Clamshell Lake sits. The surroundings are lake country bush. Roughly 32 hectares: a morning covers one end, an afternoon the other. The bank runs about 2.4 km all the way round, so one visit can cover most of it. You are 46 km from Mattawa. For a city, Gatineau is 209 km off. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Clamshell Lake

  Depth is unknown to us, and the shoreline is the better guide. Look for the band where the shallows give up and the bottom falls away. The shallow end warms first and pulls fish in ahead of the rest. Fish documented in Nipissing District include smallmouth bass, cisco, yellow perch, pumpkinseed and rock bass. What holds for the county may not hold for this water. Treat Clamshell Lake as a water to read rather than to cover.

• Seasonal Patterns

  Temperature averages peak at 18°C in July and bottom out at -13°C in January. The year splits cleanly: hard water, then open water. Firm cover through the cold months, then open water from late April. Ice clears near late April and comes back about late November in a typical year. The shoulder weeks of the open season are the productive ones. The season on Clamshell Lake rarely departs from it.

• Tackle & Baits

  Access status is simply unknown for this water. Records list it as a natural water body rather than an impoundment. There is a campsite 430 m from the water. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Where access is informal, keep it that way by behaving. Where tickets apply, they are sold in the nearest town rather than on the bank. Shoal Lake sits 0.8 km off and takes the overflow. Treat access at Clamshell Lake as something to verify.
