Conditions

Early steelhead season is underway with low returns. As of September 25, flows at Anatone were holding at 11,100 cfs and trending stable, though forecasts suggest a potential rise ahead. Water conditions favor working soft banks and edges from a distance. Consider heavier tippet and weighted steelhead patterns as flows settle into their pattern.
