Pit River, California
Modoc Plateau — Wild Redband rainbow in California's volcanic high desert
The Pit River drains the high volcanic Modoc Plateau of northeastern California before dropping into a dramatic series of cascades and gorges on its way to Shasta Lake. The accessible sections near Fall River Mills — where the Fall River, a large spring creek, enters the Pit — hold populations of wild Redband Rainbow Trout, a native subspecies adapted to the unique conditions of the Great Basin and Modoc volcanic landscape.
Redband Rainbow are distinct from coastal rainbows in both genetics and appearance — they've evolved for millennia in the intermountain high desert, developing resistance to warm water temperatures, alkaline conditions, and the large daily temperature swings of volcanic plateau streams. The result is a fish of unusual hardiness and, in the Pit River's best sections, impressive size: wild Redbands in the 14–18 inch range inhabit the cold spring-fed sections near the Fall River confluence.
The Fall River itself — a massive spring creek that maintains temperatures near 56°F year-round — is one of California's finest trout streams in its own right, with wild rainbow and brown trout feeding in flat, weedy channels that require the same technical presentation skills demanded by Hat Creek. The combination of the Pit River and Fall River in a single area creates a Northern California fly fishing destination of genuine depth and quality.
The volcanic landscape of the Modoc Plateau — lava flows, Cascade peaks on the horizon, ponderosa pine forests — gives this area a stark, dramatic character quite different from the Sierra Nevada streams to the south. Spring and fall are the finest seasons; summer can bring uncomfortably warm temperatures in the lower sections.
Fall River Mills — Pit River Access
Access from Fall River Mills via county roads to the Pit River. Multiple USFS access sites in the confluence area. Good walk-wade water near the Fall River input.
Big Bend — Gorge Access
Below Fall River Mills, the Pit River enters dramatic gorge sections. Access via Big Bend Road. The gorge requires hiking but holds large Redbands with minimal pressure.
Hat Creek Confluence Area
The area between Hat Creek and Pit River offers multiple water options in close proximity. Coordinate a trip covering both rivers for the full Northern California experience.
Redband Rainbow
California's native interior rainbow subspecies. Wild fish averaging 12–16 inches with larger fish in spring-fed sections. More heat-tolerant than coastal rainbows. Aggressive attractor dry fly feeders.
Brown Trout
Present in lower sections. Less common than Redbands. Best targeted with streamers in fall.
Combine the Pit River with Hat Creek and Fall River for a comprehensive Northern California volcanic plateau fly fishing trip.
Redband trout are more heat-tolerant than other rainbow subspecies — the Pit remains fishable in temperatures that would stress coastal rainbows.
The gorge sections below Big Bend hold the largest Redbands and see the least pressure — invest in the hike for the best fishing.
Spring (April–May) and fall (September–October) are the most consistent seasons — summer temperatures in the lower sections can limit trout activity.
