Starting in May and into August the upper Trinity river provides the fly enthusiast a chance to catch trophy brown trout, the occasional summer run steelhead and plenty of scrappy half pounders. Summer time provides conditions and water levels ideal for single handed rods, lighter lines and smaller flies. Nymphs, streamers and egg patterns will be top producers.
As the summer transitions into fall more steelhead begin to enter the Klamath and Trinity systems. These fish are willing biters and hard fighters. These chrome steelhead can be caught using most conventional fall steelhead patterns and beads. Switch rods and sinking tips are generally used as fly size increases. Autumn also sees the the return of adult chinook salmon.
As fall gives way into winter heavy adult steelhead take dominance in the river systems. Large winter steelhead require patience and persistence but offer one of the highest rewards for fly anglers. Winter steelhead are more challenging to catch and require more advanced angling skills such as making long casts with heavy sinking line and weighted flies. Winter also means cold weather so it is wise to come prepared with the correct clothing.
In the spring the temperatures begin to rise and steelhead remain the primary target, although, spring run chinook can also be caught with the right flies and presentation. Spring can also mean high flows and more challenging conditions.
