A northerly has held for 6 hours, running warmer than the water (12°C air against 10°C water). Expect fish at the southern end — the bank it is blowing into — where the drift piles food, colour and warmth together. This reads the upper water, though — a bottom bait at range feels it far less than a floater or a fish in the margins. Treat it as a tiebreaker between good swims rather than an override — features and angling pressure usually count for more.
Start with Daddy Long Legs (10-12) on a As per local method. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.
If the main plan stalls, drop to a size 14–16 midge — switch to a washing-line or suspender rig and change drift line before you change food group.
Watch for Sedge towards evening — this could be the best window of the day.
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

- Wind conditions (windy) are not ideal for this water.
- Buzzer is in its seasonal window, boosting the chance of targeted feeding.
- Reservoirs of this kind fish well at this time of year.
