  Depth is not on record here, which means reading the ground instead. Still water like this holds fish on the edges rather than out in the open.

Read it as a county summary, not a water-by-water list. Lac Cos gives up its fish to patience rather than distance.

• Seasonal Patterns

  Climate records put July near 16°C and January near -16°C. Open water arrives late and leaves early, which concentrates the fishing. After early May the shallows warm and the fish move up. Break-up sits around early May on average, with the water closing again about mid November. Reckon on open water from spring through to late autumn, with May and June the strongest. Lac Cos runs to that rhythm year in and year out.

• Tackle & Baits

  Whether the bank is open is not something our records settle. No made access is recorded, so a short walk in is the likely arrangement. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Gates get locked out of season on water like this. Barbless rules turn up on managed water more often than not. For a change of water, Lac de la Queue is 1 km distant. Nothing on Lac Cos should be assumed from this page alone.
