How to fish it · for Rainbow
When
Current conditions suit Wimbleball Lake well for summer tactics. The ripple should help fish move and feed more confidently. Very warm conditions — trout have a narrower safe zone of cool, oxygen-rich water. Fish only at first light or last light, use barbless hooks, keep fish in the water during release, and stop if fish struggle to recover.
Where
Start with Marabou Damsel (8-12) — on the point. 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.
The plan
Plan A

Start with Marabou Damsel (8-12) — on the point. 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.

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.

About this water

A 150-hectare reservoir on the edge of Exmoor with a wild, moorland character. Boat and bank; the sheltered arms provide good bank fishing. 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.
