How to fish it · for Rainbow
When
March–November
Where
Start with Chironome (12-16) — on the bob / top dropper. Evening can produce explosive surface takes — try a foam beetle or booby on a long leader. Rainbows respond to more active retrieves — try short strips between pauses.
The plan
Plan A

Start with Chironome (12-16) — on the bob / top dropper. Evening can produce explosive surface takes — try a foam beetle or booby on a long leader. Rainbows respond to more active retrieves — try short strips between pauses.

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.

Bank

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

About this water

A small family-run put-and-take fishery in the Juine valley, working the pond system around a mill that has stood since the 18th century. Straightforward stocked rainbow trout across four ponds, sold by the half or full day with no catch limit — a relaxed few hours by the water rather than a technical session. Tackle can be hired on site. Treat as provisional until current operating status is confirmed by phone.
