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.
Good late spring conditions for Glencorse Reservoir
Good wave on — drift country. Drift fishing weather — three flies on a long leader.
Conditions are not ideal but fishable at Glencorse Reservoir. The ripple should help fish move and feed more confidently.

How to fish it · for brown trout
When
Conditions are not ideal but fishable at Glencorse Reservoir. The ripple should help fish move and feed more confidently.
Where
Start with Buzzer (14-16) on a slow figure-of-eight or hang under indicator. If that does not produce, switch depth or speed before changing the pattern entirely. In the ripple, a bushy searching dry (Hopper, Shipman's, Elk Hair Caddis) outperforms flush emergers — it stays visible and holds the surface tension.

The plan
Plan A
Start with Buzzer (14-16) on a slow figure-of-eight or hang under indicator. If that does not produce, switch depth or speed before changing the pattern entirely. In the ripple, a bushy searching dry (Hopper, Shipman's, Elk Hair Caddis) outperforms flush emergers — it stays visible and holds the surface tension.
Plan B
If fish refuse on top, drop to a buzzer under an indicator at different depths.
Watch for
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
Either bank or boat
Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.
