Rich Sierra reservoir up by Portola, holding chunky wild rainbows that grow fat on a diet of blood midges and damsels. This is premier stillwater nymphing — a static blood midge fished over the weed beds under an indicator is the classic Davis method, and the trick is varying your depth until you find the band the fish are sitting in. Tube and boat water. Ice-off in spring and the autumn are the prime windows, with damsel and Callibaetis fishing through the summer.
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.

The plan
Plan A · Plan B · what to watch · bank or boat
With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. In the calm, a single dry fly or a slowly-fished nymph tends to out-fish an active retrieve.
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.
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Flat calm suits bank fishing near features — points, weed beds, and inflows where fish patrol.
