Given steady pressure and overcast conditions typical of April, work the windward margins and drop-offs from first light, as spring trout respond well to cloud cover and reduced light penetration. If you encounter the SSW wind gusting to 21mph, position yourself on the sheltered lee shore during mid-morning when wind strength peaks, then return to the windward side as conditions ease toward noon. Try nymphs on intermediate lines in the 5–9 a.m. window while water temperature sits around 11–12°C; if trout are inactive by 10 a.m., switch to small dries or small fish patterns to trigger more aggressive takes. Given the light precipitation and steady barometric pressure, expect the peak window to extend beyond typical noon slump—continue fishing until conditions deteriorate rather than stopping early. If visibility remains poor beneath the 88% cloud cover, darken your patterns and fish slower, deeper retrieves to help trout locate your fly.
