Lac du Plongeon near Mandeville: Fishing Spots, Seasons and Access

• Overview

  Lac du Plongeon sits within Mauricie in Quebec. Elevation runs to 433 metres. This is a pocket water of some 3 hectares, and every part of it is reachable from the bank. It is one of the smaller waters we list in Mauricie. Head to Mandeville, 16 km away, for anything you forgot. For a city, Trois-Rivières is 72 km off. The nearest boundary is well away, so one set of rules covers the water.

• Where to Fish on Lac du Plongeon

  Open data we checked carries no depth for this water. The shallow end warms first and pulls fish in ahead of the rest. Read the surface for the wind lane, then fish the edge of it. Mauricie records list northern pike, brook trout, walleye and yellow perch among the fish reported. County records show the wider picture rather than this one place. On Lac du Plongeon the quiet end is the one worth the extra effort.

• Seasonal Patterns

  Climate normals give 18°C for July and -14°C for January. The year splits cleanly: hard water, then open water. Once it clears, about late April, the fishing comes on quickly. Break-up sits around late April on average, with the water closing again about late November. Spring is short and heavy here; autumn is longer and steadier. Anyone fishing Lac du Plongeon regularly works to that calendar.

• Tackle & Baits

  The paperwork position is blank for this one. Public mapping records no formal access here, so plan for a walk and soft ground. A small crankbait along the drop and a worm in the thick stuff cover the bass. Read any posted signs at the access point rather than assuming. Fishing rules and camping rules are set separately here. Lac Rosemonde at 0.7 km is the sensible second choice. Where Lac du Plongeon is concerned, a local answer beats a written one.
