Lac Grothe in Laurentides: How and When to Fish It

• Where to Fish on Lac Grothe

  No chart reached our records; the first cast is your sounding. Bays and points beat straight shoreline every time on water like this. Still water like this holds fish on the edges rather than out in the open. Survey and observation records for Laurentides include pumpkinseed, smallmouth bass and yellow perch. These are county-wide records, so not all of them will be in this water. The near bank of Lac Grothe is often the one people ignore.

• Seasonal Patterns

  Typical July readings run about 19°C; by January the average is down near -13°C. Four clear seasons, with a proper winter at one end. The lid arrives early and lasts until roughly late April. On the long-run averages the water opens up around late April and starts locking again about early December. Look to early summer and the first cool weeks of autumn. On Lac Grothe the same rules apply, with local timing.

• Tackle & Baits

  We have no record of the rules that apply on this bank. This is a natural basin, not a dammed one. Public mapping records no formal access here, so plan for a walk and soft ground. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Check whether a boat is allowed before you tow one. Night access is frequently treated as a separate matter. If the gate is shut, Lac a Lafleur at 0.6 km is the nearest alternative. For Lac Grothe in particular, ask before you travel.
