Winter Steelhead in Northern California: What Anglers Should Expect in the Months Ahead

Winter steelhead season in Northern California carries a special kind of anticipation. Storms roll through, rivers change color overnight, and every swing brings the possibility of a fish that will stay in your memory for years. Whether you’re planning a Spey trip, an indicator day, or a coastal mission, winter is when rivers come alive — and when preparation matters most.

At NorCal Spey, we spend our entire winter chasing these fish across the Trinity River, the Lower Sacramento, and the rugged Northern California coast. Here’s what you can expect this season and how to set yourself up for success.

⸻

Weather, Flows, and The Winter Rhythm

Winter steelheading isn’t predictable — and that’s part of why it’s so addictive. Storm pulses create short-lived but incredible windows of opportunity.

Trinity River

The Trinity typically remains the most stable winter fishery.

• Moderate storms improve the bite

• Water temps hold better than coastal systems

• Spey and indicator tactics both shine

Coastal Rivers

This is where things get wild.

• Rivers blow out fast

• They drop and green quickly in most cases

• The bite window may only last 24–72 hours

When flows line up with timing, these coastal rivers offer some of the most explosive steelhead fishing in California.

Lower Sacramento

While not a traditional winter steelhead river, the Lower Sac offers:

• Consistent trout fishing

• Occasional half-pounders

• A backup option when storms are rolling

⸻

Choosing the Right Technique: Swing, Indicator, or Light Tackle

Your approach depends on the river, the conditions, and your comfort level.

Spey

Winter swing tactics often rely on:

• Skagit heads

• Medium to heavy sink tips

• Intruders, muddlers, and sparse winter patterns

The grab in winter feels different — unmistakably powerful.

Indicator

On higher or colder water days, indicator fishing can shine.

This is where Beyond the Swing comes in:

• Dead-drifting worms, eggs, or nymphs

• Covering seams and softer travel lanes

• Excellent for anglers wanting more consistent action

Light Tackle

For anglers who enjoy gear fishing, light tackle provides another effective, mobile way to hunt winter steelhead when water is moving.

Fly Patterns That Work in Winter

Some of our winter staples include:

• Black/blue intruder style flies

• Purple or pink marabou patterns

• Sparse winter muddlers

• Glow-bug or bead variations under indicators

• Worm patterns (steelhead candy)

Matching fly choice to water clarity and speed is part of the equation — and part of the fun.
