The plan
Plan A

Start with Marabou Damsel (8-12) — on the point. As evening approaches, switch to dries or emergers if you see surface activity.

Plan B

If the daddy is being refused, drop to a hopper or a single foam beetle and cover rising fish individually.

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

The largest of the Midlothian reservoirs, set into the hills south of Edinburgh in a shallow basin that is also, incidentally, a Ramsar wetland and a nationally important roost for pink-footed geese. Scottish Water own the fishing; wild brown trout are the quarry. No rainbows. The trout are not large — half a pound is respectable, three-quarters is a good one — but they are properly wild, they come to a dry fly when the olives are on, and they are as handsome a Scottish hill-loch brown as you'll find within half an hour of the city. Bank fishing only (the geese have the stronger claim on the boats). Fly only. Bring midge repellent in July; you will need it.
