Morning Tricos and Baetis, large craneflies still skittering about

Conditions

The Big Lost is running low through mid-August, with flows at 416 cfs on the lower sections as of the report date. Trout are educated and selective, demanding fine tippets and precise presentations. Expect Tricos and Baetis in the mornings, with large craneflies skittering about and hoppers producing throughout the day. Cold morning temperatures in the 30s push the better fishing window to mid-morning through afternoon, so plan your timing around the warming trend.

Techniques

  • Better fishing shifted to mid-morning into afternoon due to cold morning temps
  • Hoppers turning fish when searching water; smaller, more imitative caddis and mayfly patterns working on selective feeders
  • Trout are well seasoned and selective; fine tippets and precise presentations are key to success
