How to fish it · for Rainbow
When
The buzzer is on at Glencorse Reservoir.
Where
Start with Marabou Damsel (8-12) — on the point. Early in the day, try buzzers on a slow figure-of-eight or a booby on a fast-sink line near the bottom. Rainbows respond to more active retrieves — try short strips between pauses.
The plan
Plan A

Start with Marabou Damsel (8-12) — on the point. Early in the day, try buzzers on a slow figure-of-eight or a booby on a fast-sink line near the bottom. Rainbows respond to more active retrieves — try short strips between pauses.

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

Watch for Sedge towards evening — this could be the best window of the day.

Bank, sheltered shores

In wind, bank fish the lee shore — boats can anchor in productive areas if conditions allow.

About this water

A narrow, deep reservoir in a wooded glen seven miles south of Edinburgh, reachable from the city in twenty minutes if the traffic is kind and the Flotterstone car park hasn't filled up. Scottish Water own it; the Glencorse Angling Improvement Association lease the fishing. Fly only, boat and bank, stocked brown and rainbow trout on a wild brown base. The reservoir is long and thin, walled by conifer plantation on one side and heather slopes on the other, and it takes the weather personally — a breeze that was friendly at Flotterstone can become something else entirely once you're halfway down the west shore. It is, for a great many Edinburgh anglers, the first water they ever fished properly, and most of them still come back.
