The water
Lower Sacramento River
The Lower Sac through Redding is Northern California's flagship: a broad, food-rich tailwater loaded with hard-fighting rainbows, plus seasonal steelhead and salmon moving up from below and striped bass in the lower river. Spring through fall is prime for trout, on blue-winged olives, midges, March Browns, caddis, and assorted mayflies; fall salmon runs bring eggs and baitfish patterns into play. This is predominantly drift-boat water — many banks are private — but walk-in fishing exists at city parks and public riverfront greenbelts around Redding, with boat ramps and bridge crossings providing the main access. Salmon and steelhead seasons carry special regulations, including gear restrictions and seasonal closures in some reaches; check current CDFW rules. Full Lower Sacramento guide
Trinity River
The Trinity, flowing from Lewiston Lake toward the Klamath, is California's most dependable steelhead river. The run fishes from August through April with peak fall and winter windows, while upper tailwater sections hold resident trout through summer and early fall. This is swung-fly and nymph country: aquatic insects, eggs during salmon spawning, and baitfish patterns for the migratory fish. Access is good along the Highway 299 corridor and through BLM and Forest Service lands, and a designated fly-only section below Lewiston Dam offers walk-in wade fishing. Seasonal steelhead regulations govern much of the river, including barbless hooks and selective harvest.
Lower Yuba River
The Lower Yuba, in the northern Sierra foothills east of Marysville, is a wild-trout tailwater with an outsized reputation for mayfly fishing — strong BWO and PMD hatches, caddis, stoneflies, and egg bites around salmon spawning, plus midges and small emergers for the selective fish. Late winter through spring and again in fall are the best windows; summer fishes in mornings and evenings but gets tough at low flows and high temperatures. Access centers on public put-ins and bridges near the Highway 20 crossing, with walk-in options on public lands — much of the corridor is private, so mind posted boundaries. Trout fishing in popular reaches is barbless, catch-and-release water; steelhead and salmon seasons carry their own rules.
McCloud River
The McCloud is the canyon freestone of California legend, running cold through its canyon east of Mount Shasta, holding wild rainbows and browns. Late spring through early fall is the season, once snowmelt subsides and the pocket water clears; summer brings consistent dry-fly and nymph fishing through the pools and pockets. Mayflies, caddis, and stoneflies make up the hatch base, and terrestrials and attractor dries earn their keep in the canyon sections. Forest Service roads and trailheads provide walk-in access through national forest reaches, with some water adjacent to private property. Sections carry wild-trout special regulations on tackle and harvest — confirm current rules.
Fall River
The Fall is a large, glassy spring creek near Fall River Mills, and one of the most technical fisheries in the state. Clear, cold spring water supports steady hatches — PMDs, BWOs, midges, caddis — and boat-based sight fishing for substantial rainbows and browns; mid-summer evenings can be the prime mayfly window. Sculpin patterns work the deeper channels. Access is the catch: private property lines most of the shoreline, so nearly everyone fishes from a boat via public ramps and marinas in the valley, with only limited wade access at public easements. Regulations protect the wild stock — review local rules on boats, harvest, and gear before going.
Hat Creek
Hat Creek's designated wild trout section near Burney is a piece of California fly fishing history: flat, brush-lined spring-creek water where rainbows and browns demand long leaders and small flies. Mayflies, caddis, and midges provide the technical fishing, with terrestrials and small nymphs as staples; late spring through early fall is prime, and shoulder seasons produce on midges and BWOs. Public access is good in the Powerhouse and lower Hat Creek areas, with walk-in parking and trails lining much of the wild trout section on state and federal lands. Key reaches are catch-and-release, barbless-hook water under restrictive regulations.
Pit River
The Pit is the hardest river on this list and possibly the best value: a bouldery, brawling wild-rainbow freestone east of Redding that stays uncrowded because the wading is miserable. Spring through fall is the season; summer is very productive if you can keep your feet. Nymphing small mayfly and caddis patterns through the deep, bouldery structure is standard. Access is by steep trails and pull-outs on national forest land, and most anglers work defined access points near bridges and power facilities. It is managed as a wild rainbow fishery with specific harvest and gear rules, and flows change with hydroelectric operations — check releases before you commit to a stretch.
Upper Owens River
The Upper Owens winds through open meadow between Mammoth Lakes and Crowley Lake, and it fishes year-round — the headline is fall and winter, when migratory rainbows, browns, and cutthroat move up out of Crowley. Spring and early summer are also productive as snowmelt moderates and hatches build. Mayflies, midges, and caddis cover the dry-and-nymph game; sculpin and baitfish patterns move the big migratory fish in deeper pools. Walk-in access is extensive across meadows and BLM lands via dirt roads and informal parking. Certain sections run barbless fly-only with seasonal restrictions protecting spawning fish — read the Eastern Sierra regulations carefully.
Seasons at a glance
| Window | Where to be |
|---|---|
| Winter | Trinity steelhead; Upper Owens migratory fish; midge fishing on tailwaters |
| Spring | Lower Sac and Lower Yuba mayflies; season builds everywhere as flows stabilize |
| Summer | McCloud, Pit, Hat Creek, Fall River; Eastern Sierra wide open; Yuba mornings and evenings |
| Fall | Peak on nearly everything — Lower Sac egg bites, Trinity steelhead arriving, Owens migratory fish, spring creek BWOs |
If one season had to carry a California trip, it would be fall: trout rivers still fishing, steelhead arriving, and crowds thinning.
Beyond trout
California's warmwater and salt options are strong enough to build separate trips around. The Delta holds striped bass, largemouth, smallmouth, and panfish in a maze of sloughs and tules. San Francisco Bay and the adjacent surf — Ocean Beach, Crissy Field — give shore anglers surf perch and other marine species on flies. And the Los Angeles River supports a legitimately good urban carp fishery within sight of downtown.
Licenses and regulations
Fishing is managed by the California Department of Fish and Wildlife (CDFW). Residents and nonresidents need a valid sport fishing license for inland and coastal waters; there is no separate trout stamp, but report cards are required for certain species including steelhead and salmon. Special regulations are the norm on the state's best water — fly-only sections, barbless requirements, catch-and-release reaches, and seasonal closures are flagged per river above. Regulations change annually; verify current CDFW rules before any trip.
What's changing
The big story is the Klamath: removal of the four lower dams was completed in 2024, and CDFW and NOAA expect improved steelhead and fall-run Chinook access beginning in 2025, though biologists caution that sediment and variable flows will make the first season or two unpredictable. CDFW's 2025 regulations booklet made only minor adjustments otherwise — a handful of southern Sierra small-stream closures to protect native trout, and a new gear rule on the Lower Sacramento prohibiting bait within 250 feet of the river below Red Bluff. Wildfire recovery continues on the North Fork Feather and upper Kern, where some previously closed roads reopened in 2024 but parking remains limited.
Where to start
One weekend, one basecamp: Redding. Float the Lower Sac one day with a guide, then spend the second day inland — Hat Creek or the Fall River if you want technical spring-creek fishing, the Pit if you want wild rainbows and solitude and don't mind the wading. Spring or fall gives you the best of it. If your weekend falls in winter, point north to the Trinity and swing for steelhead instead; if you're based in Southern California, the Upper Owens out of Mammoth is the year-round answer.
