Lac Cosson Fishing Guide, Outaouais, Quebec

• Overview

  In Quebec, Lac Cosson belongs to Outaouais. It sits at 333 metres above sea level. Surface area runs to about 8 hectares — small enough to read in one session. Head to Deep River, 32 km away, for anything you forgot. For a city, Gatineau is 175 km off. Also worth knowing: Lac Dontenwill 1.7 km, Lac Malte sits 1.8 km out, Lac Clarke 2 km, Lac Michaux sits 2.5 km out and Lac du Mene 2.6 km. One jurisdiction covers this water end to end.

• Where to Fish on Lac Cosson

  Nothing we hold settles how deep this runs. Read the surface for the wind lane, then fish the edge of it. Where the bottom changes texture, fish gather; find that line. Fish documented in Outaouais include pumpkinseed, yellow perch, smallmouth bass and rainbow smelt. Those are county-wide records, so not every one of them will be in this water. Fish Lac Cosson to its features, not to its size.

• Seasonal Patterns

  In an average year July sits at 18°C and January at -14°C. A hard winter is normal, and the thaw brings a strong few weeks. Hard cover is dependable here; it goes around late April. Climate averages put the opening at about late April and the closing near late November. Just after the ice goes and just before it returns, the fishing lifts. That is the shape of the year on Lac Cosson.

• Tackle & Baits

  Whether the bank is open is not something our records settle. Nothing formal is recorded here: no ramp, no car park, no marked path. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Rules differ from one water to the next round here. Rules for boats are stricter than rules for the bank in many places. Lac Dontenwill at 1.7 km is the sensible second choice. Check the position on Lac Cosson before loading the car.
