How to fish it · for Rainbow
When
Conditions are not ideal but fishable at Threipmuir Reservoir. The ripple should help fish move and feed more confidently.
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

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.

Bank

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

About this water

A walkable-from-Balerno Pentlands reservoir sitting inside Edinburgh's city boundary — which still seems implausible the first time you stand on the bank. Scottish Water-managed, mixed wild and stocked brown and rainbow trout, fly only. The water is smaller and shallower than Glencorse, the weed growth more generous, and the trout accordingly better educated. Buzzer and dry-fly fishing dominate from May onwards; in September the bank hoppers start coming down and the fishing turns into the sort of thing you could do forever if the light held. The walk out from the Red Moss car park takes twenty minutes and is most of the reason people come — bringing a rod is really just a formality.

  • Peat
Why this score
  • Buzzer is in its seasonal window, boosting the chance of targeted feeding.
