How to fish it · for trout
When
April–September
Where
Start with Spent Gnat (12-14) on a As per local method. If that does not produce, switch depth or speed before changing the pattern entirely.
The plan
Plan A

Start with Spent Gnat (12-14) on a As per local method. If that does not produce, switch depth or speed before changing the pattern entirely.

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.

Either bank or boat

Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.

About this water

Altnahinch sits in exposed peaty moorland at the head of the Bush system. It is a classic shore-fishing reservoir in rougher country rather than an easy-access stocked park lake. The official DAERA material explicitly points anglers towards small attractor wets such as Bibio and Peter Ross, which tells you a lot about the venue's practical character.
