Hatch Status

Blue-winged olives can become more important this time of year, especially when cloud cover and cooler conditions move into the area.

Conditions

The Selway is running at a comfortable 620 cfs as of September 27, with flows continuing to fall into late September. Dry-dropper combinations are proving effective, and you should expect afternoon mayfly activity as temperatures cool. Terrestrials remain worth carrying, and blue-winged olives are becoming more important in the hatch rotation.

Techniques

  • Dry-dropper combinations are a good choice for covering a variety of water without constantly changing rigs.
