Head to
Wind driftSE wind
North-western end

A southeasterly has held for 10 hours, running warmer than the water (20°C air against 12°C water). Expect fish at the north-western 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.

How to fish it · for Trout
When
The buzzer is on. Lake Olive may also come into play as the day warms.
Where
Work Cat's Whisker on the bob and Booby on the point.
The plan
Plan A

Work Cat's Whisker on the bob and Booby 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

Buzzer may strengthen through the middle of the day as conditions warm.

Bank

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
