How to fish it · for Pike
When
Pike are feeding aggressively as water cools, building reserves for winter. Weed is dying back, concentrating both pike and prey fish into predictable holding areas.
Where
Autumn/winter pike on the fly — big fish season. Pike are putting on condition and take large flies confidently. Fish dropping weed edges, deep channels, and structure. Start with a sinking line and move to faster-sinking as the water cools. Biggest pike of the year come in this window.
The plan
Plan A

Autumn/winter pike on the fly — big fish season. Pike are putting on condition and take large flies confidently. Fish dropping weed edges, deep channels, and structure. Start with a sinking line and move to faster-sinking as the water cools. Biggest pike of the year come in this window.

Plan B

If the main plan stalls, drop to a size 14–16 midge — switch to a washing-line or suspender rig and change drift line before you change food group.

Watch for

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Bank

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

Ranked for today
Pike fly box

Probably the best pike fly fishing window of the year. Cooling water activates pike metabolism and baitfish shoal up before winter, concentrating the predators. Fish are aggressive feeders moving to windward banks, dropoffs, and points where baitfish are pushed. Large profile baitfish streamers on intermediate lines retrieved at medium pace, with pauses at structure edges. Count-down retrieves to find the active depth. Fish move — cover ground rather than working one spot.
