  Look for Grosbeak Lake in the Nipissing District part of Ontario. The surroundings are lake country bush. The water measures roughly 8 hectares, so nothing here is far from anything else.

• Where to Fish on Grosbeak Lake

  Nothing we hold settles how deep this runs. Still water like this holds fish on the edges rather than out in the open. The productive water is a rod length or two out, not a hundred. Across Nipissing District, recorded fish include smallmouth bass, cisco, yellow perch, pumpkinseed and rock bass. County records show the wider picture rather than this one place. Grosbeak Lake repays a walk before the first cast.

• Seasonal Patterns

  On the long-term average, July reads 18°C and January reads -13°C. Fishing here follows the temperature more than the calendar. Break-up comes around late April, and the run that follows is short and strong. The open-water window runs from around late April to about late November in an average year. The first weeks of open water and the last are the ones to plan for. Anyone fishing Grosbeak Lake regularly works to that calendar.

• Tackle & Baits

  Whether you may fish here is not something records settle. No built facilities appear in mapping around this water. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. A landowner's word beats anything printed elsewhere. Fishing rules and camping rules are set separately here. Bishop Lake at 1.2 km is the sensible second choice. Nothing on Grosbeak Lake should be assumed from this page alone.
