How to fish it · for Rainbow
When
The buzzer is on at Walthamstow Reservoirs. The ripple should help fish move and feed more confidently.
Where
Start with Viva (10-12) on a figure-of-eight with occasional strip. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely. In the ripple, a bushy searching dry (Hopper, Shipman's, Elk Hair Caddis) outperforms flush emergers — it stays visible and holds the surface tension.
The plan
Plan A

Start with Viva (10-12) on a figure-of-eight with occasional strip. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely. In the ripple, a bushy searching dry (Hopper, Shipman's, Elk Hair Caddis) outperforms flush emergers — it stays visible and holds the surface tension.

Plan B

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

Watch for

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