Largemouth bass

Best: spring and fall

The headline act on most American reservoirs. Relates to cover: docks, brush, grass edges and points. Prime chasing season. Work moving baits on points and pockets: spinnerbaits, chatterbaits and squarebills, with a stick worm behind for followers.

Smallmouth bass illustration

Smallmouth bass

Best: May-Oct

Current and rock. Finds gravel flats, boulders and drop-offs, and fights far above its weight. Peak season. Tubes, jerkbaits and swimbaits around gravel points, boulders and current seams.

Rainbow trout illustration

Rainbow trout

Best: Apr-Jun, Sep-Oct

The workhorse of western rivers: riffles, seams and dry-fly eats. Prime dry-fly and hopper season. Match the hatch morning and evening; nymph the seams midday.

Crappie illustration

Crappie

Best: Nov-Mar

Brush piles, bridge pilings and standing timber. The fish fry favorite. Spawning shallow around cover in spring; jigs under a float near buck brush and laydowns.

About this water

2,700 acres behind Warm Springs Dam, Sonoma County, CA. Wine country's quiet two-story lake.

Fishing Lake Sonoma: the full guide

The Warm Springs maze

Lake Sonoma floods Dry Creek's forks into a many-armed maze behind Warm Springs Dam: 2,700 acres of madrone hills, no-wake serenity (the whole lake caps at 10 mph in the arms) and a two-story fishery wine country forgets it owns.

Bass in the arms

The lake's largemouth and smallmouth work the endless points and drowned oaks: spring wakes the coves (senkos, spinnerbaits in the stained arms), summer runs the deep points at dawn (drop shots over 20-40 ft), and the no-wake calm makes every cove a kayak fishery. Quality runs honest: 5-pound fish surprise no one.

The steelhead below

Landlocked steelhead (the dam's mitigation stock) patrol the cold band: trolled spoons and hoochies at 30-60 ft through summer, shallow flatlines in the cold months: wine country's only salmonid troll. The fish run 14-20 inches of confused chrome: a novelty fishery with real pull.

Sonoma practicalities

The public ramp and marina serve the south end: the arms reward paddle craft (rentals at the marina): and the visitor center's hatchery tours explain the steelhead story. Healdsburg's tasting rooms sit twenty minutes east: the fish-then-flight itinerary is the local special.

Common questions

Are there really steelhead in Lake Sonoma?

Landlocked mitigation fish, yes: trolled at depth all summer. The dam's hatchery raises the sea-run cousins below: the lake keeps its own.

Is Lake Sonoma good for kayak fishing?

Among NorCal's best: no-wake arms, endless coves, bass in every one. Yorty Creek's car-top launch opens the quiet north end.
