Boise River

The Boise River between Middleton and Eagle Road is fishing consistently through a mix of caddis, PMDs, midges, and grasshoppers. Fish concentrate in deeper holes and tail outs early and mid-afternoon before moving into faster water as the day warms—nymphing is your most reliable approach, though dry action remains in play. As of August 15, flows are running low and stable at 418 cfs, so plan your float carefully and fish early before recreational traffic picks up. Water temperatures climbing into the upper 60s and low 70s make evening fishing prime as the day heats.
