  • Use a boat or cover water methodically from shore, focusing on soft shelves and structure instead of random midriver drifts.
  • A stonefly lead with a smaller mayfly dropper is the cleanest all-day setup in mixed spring conditions.
  • If the water is clear and stable, mix in short streamer swings along banks and logjams to move the more aggressive fish.
FlowSpring flows can rise quickly with weather, especially across broader valley reaches and below tributary input.
Water TempCold water keeps the better fish close to soft banks, depth breaks, and current shelters.
WeatherClouds help. Wind can shut down surface visibility even when bugs are present.
