How to fish it · for rainbow
When
The buzzer is on at Wimbleball Lake. The ripple should help fish move and feed more confidently.
Where
Start with Booby (8-10) on a fast strip on floating line or static on sinking. 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 Booby (8-10) on a fast strip on floating line or static on sinking. 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 change drift line before you change food group.

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.

Stocked with rainbows and brown trout; wild browns from feeder streams add quality. The Exmoor setting means clean water and genuine solitude. Buzzer and olive hatches from April; mayfly in places. Managed by South West Lakes Trust.
