Conditions

The Big Lost is shaping up well for the outlook window. The North Fork is clearing and the main stem holds fish; the East Fork draws heavy pressure, so plan to move water and seek unpressured lies. Flows remain slightly elevated but manageable for confident waders. Morning hatches of Tricos and PMDs fade by afternoon, but crane flies persist through the day. Bring an assortment of attractor patterns in both large and small sizes, plus nymphs and streamers to cover your options.
