How to fish it · for Pike
When
Pike are under severe thermal stress. Post-release mortality is high. Defer the session until water cools below 19°C.
Where
Water at 34.2°C. This is the line where catch-and-release kills pike. Do not fish for them today.
The plan
Plan A
Water at 34.2°C. This is the line where catch-and-release kills pike. Do not fish for them today.
Plan B
Fish early and late, try deeper during the heat of the day with a fast-sinking line.
Watch for
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Either bank or boat
Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.
