A patient day, if you fancy it
Glassy and bright — hard work without a breeze. A flat lough is a quiet lough — wait for the breeze.

How to fish it · for Trout
When
Late spring to summer; note the left-margin closure below Coballes bridge until 15 June.
Where

The plan
Plan A

Start with CDC F-Fly (Black) (18-22) on a As per local method. Early in the day, nymphs and buzzers fished slowly tend to outperform attractors.

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.

Bank

Flat calm suits bank fishing near features — points, weed beds, and inflows where fish patrol.
