How to fish it · for Rainbow
When
Buzzers from April; sedges and damsels through summer evenings; back-end blob and booby work October before close. Blagdon is more intimate than Chew — pace yourself.
Where
Lugg Bay and the open boat marks on the western end. Drift lines through the middle hold fish in spring and summer.
Method
Floater with buzzers under indicator in spring; midge-tip and team of three through summer. Drift broadside; the lake is small enough to read each lane carefully.
Kit
10 ft #7 boat rod; floating, intermediate and fast-intermediate lines; 6 to 8 lb fluoro. Drogue and a long-handled net.
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.
