Best Smallmouth Bass Rivers in California for Fly Fishing

The Sacramento River is California’s largest river and an often-overlooked smallmouth bass fishery — the lower Sacramento from Redding downstream through Red Bluff and Corning holds established smallmouth populations in its rocky runs and ledge formations, often sharing water with the river’s famous steelhead and salmon runs. The Sacramento’s clear, cold upper reaches from Redding to Red Bluff offer the most consistent smallmouth fly fishing, with fish averaging 12–15 inches in the rocky shoal sections and occasionally larger in the deeper pool areas.

Clouser Minnows and Woolly Buggers are the Sacramento’s most consistent smallmouth producers. Work Clousers in chartreuse/white through the current seams and along the rocky ledge formations that punctuate the upper river, and strip Woolly Buggers slowly through the deeper pool sections during midday. The Sacramento is primarily a float-fishing river for smallmouth — guided drift boat trips from Redding and Red Bluff provide the most effective access to the productive water, though bank and wade access exists at multiple points along Interstate 5.

The North Fork Feather River flows through one of California’s most dramatic canyons, dropping from Plumas County’s high country through Feather River Canyon to Lake Oroville. The section below Oroville Dam in Butte County, and the lower canyon sections accessible by road on Highway 70, hold excellent smallmouth bass populations in clear, cold tailwater and free-flowing canyon river. The North Fork’s combination of cold, highly oxygenated water and rocky canyon character produces hard-fighting, well-conditioned smallmouth that average 13–16 inches in the best sections.

Crayfish patterns and Deceivers are the North Fork Feather’s most effective flies. The canyon’s rocky substrate and clear water mean bass are selective and respond best to realistic patterns presented carefully on long leaders. Dead-drift a weighted crayfish pattern along the rocky bottom of the pools and runs, then strip it erratically as it begins to swing. Deceivers in natural minnow colors work well in the deeper, faster sections of the canyon. Access requires hiking to the river in most canyon sections — the primitive roads along the canyon provide trailhead access to the best water.

The Stanislaus River flows from the Sierra Nevada through Calaveras and Tuolumne counties before joining the San Joaquin River near Ripon. The lower Stanislaus from Goodwin Dam downstream through Knights Ferry offers productive smallmouth bass fly fishing in a beautiful Gold Country setting, with rocky runs, pool sections, and the historic covered bridge at Knights Ferry providing a memorable angling backdrop. Smallmouth populations in the lower Stanislaus are well-established, with fish averaging 12–14 inches and responding aggressively to streamers and Clouser Minnows from May through September.

Streamers and Clouser Minnows cover most Stanislaus smallmouth situations. Work streamers in natural minnow colors through the current seams below the rocky shoal formations, and use Clouser Minnows to cover the faster riffle sections. The Knights Ferry section offers excellent wade fishing access from the California State Parks parking area, with a natural rock and gravel bottom that provides good footing. The river’s Gold Country foothill setting creates warm but not extreme summer water temperatures that keep bass active through the season.

The American River — its North, Middle, and South Forks converging in the Sierra foothills before flowing through Sacramento to the Sacramento River — provides both urban and wild-setting smallmouth bass fly fishing depending on which section you choose. The lower American through Sacramento’s Jedediah Smith Memorial Bicycle Trail corridor offers convenient urban access to surprisingly productive smallmouth water. The Middle Fork American through the Auburn State Recreation Area provides a more remote, canyon river experience with excellent bass populations and spectacular scenery.

Poppers and Woolly Buggers are the American River’s most effective fly choices across its urban and wild sections. Evening popper fishing on the lower American through Sacramento produces exciting surface strikes from June through September as bass move into the shallows to feed in fading light. Woolly Buggers strip well through the deeper canyon pool sections of the Middle Fork. Use 1X–2X tippet on the American — the river produces larger-than-average California smallmouth, particularly in the Middle Fork canyon sections.
