Idaho Fish Report

The giant Hex mayfly hatch has started to wane in some areas. The mayflies hatch around 9 p.m. Please remember no bait, no treble hooks and catch-and-release for redband trout. ‌

Numerous mayflies are hatching, therefore small pheasant tail nymphs fished on clear intermediate fly lines with fluorocarbon leaders can be effective. ‌

The river above the Sprague River confluence is crystal clear with few redband trout, currently. This section has more brown trout. Brown trout can be targeted above and below Spring Creek. ‌

Large streamers and leech patterns are more effective lower in the river towards the mouth. Check Williamson River Flows.
