The highest of the Aberystwyth AA waters — five hundred metres up in a glacial cwm on the north flank of Plynlimon, source of the Rheidol itself. Eight hectares of properly remote water with no tarmac access; you walk in. Truly wild brown trout, small and dark from the peat-stained water, and the kind of silence you have to climb for. Bring weather gear.
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.

Today's tactical plan

Plan A · Plan B · what to watch · bank or boat
The plan
Plan A
With limited drift, anchor or fish static from sheltered positions. Work Pheasant Tail Nymph on the bob and Diawl Bach on the point.
Plan B
If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.
Watch for
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Bank, sheltered shores
Strong wind makes boat fishing difficult — sheltered bank spots near lee shores will fish best.
