- Free fishing
- Fly only
A southeasterly has held for most of a day, running colder than the water (12°C air against 15°C water). The end it blows into is taking that chilled surface water, so try the sheltered south-eastern end instead — off the back of the wind, where the undertow returns food along the bottom. That chill sits in the top of the water, though, and the bed is slower to feel it — on a bottom bait it is the undertow, not the temperature, that puts you at this end. Treat it as a tiebreaker between good swims rather than an override — features and angling pressure usually count for more.
Start with Perch Fry (8-10_long_shank) — on the point. If that does not produce, switch depth or speed before changing the pattern entirely.
If the daddy is being refused, drop to a hopper or a single foam beetle and cover rising fish individually.
Watch for Murrough towards evening — this could be the best window of the day.
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

A reasonable day here, though wind isn't quite in the sweet spot.

- Wind conditions (strong) are not ideal for this water.
- Temperature (cool) is in the sweet spot for autumn fishing.
- Daddy Longlegs are in their seasonal window, boosting the chance of targeted feeding.
- Reservoirs of this kind fish well at this time of year.
- Trout 1 March → 31 October
