Hatch Status

Throughout morning and afternoon, expect mixture of Midges, BWOs, PMDs, Baetis, and Callibaetis in the air. Evening PMD spinner fall as sun drops below horizon is when dry fly game turns on.

Conditions

The Owyhee is a standout fishery with warmer-than-normal water temperatures fueling strong hatches throughout the day. Midges, BWOs, PMDs, Baetis, and Callibaetis are active, with the evening PMD spinner fall particularly strong. Fish are in excellent condition but handle with care using a rubber net only. As water temps climb, expect more surface activity and consider targeting cooler riffles to protect stressed fish.
