Fly Fishing Green River - Section C

Fly fishing Green River – Section C represents the final stage of the river's famous high-density trout fishery before the water becomes more challenging to navigate and the river's character changes. Located in the beautiful red-rock canyon country of Northeast Utah, Section C maintains the incredibly cold, clear, and nutrient-rich waters characteristic of the Flaming Gorge tailwater. This stretch is slightly more remote than the upper two sections, offering a wilder feel while still providing world-class angling for those willing to commit to the full float trip down the Green River Basin. It rewards those seeking solitude without sacrificing the chance at trophy trout.

Section C is defined by its maturity as a tailwater, featuring wide, sweeping bends, long, slow-moving glides, and deep-cut pools. The structure is less chaotic than the upper sections, with predictable current seams and vast gravel bars that transition into deep slots. This slower, more deliberate flow creates perfect holding water for large fish and allows for consistent nymphing and streamer fishing. The terrain is dominated by high desert canyon walls and thick stands of riverside willows, which demand accurate casts to tight cover. The crystalline clarity of the Green River requires absolute precision and low-visibility tackle, particularly when casting to risers in the slow pools.

The species found in Green River Section C include thriving populations of wild brown trout, acrobatic rainbow trout, and numerous mountain whitefish. While all three sections hold incredible numbers of fish, Section C is known for producing some of the largest, most experienced brown trout, which utilize the deep pools and heavy cover for safety. Rainbows are equally robust and contribute to the river's exceptional population density. Fish often exceed 18 inches, with true trophy potential existing for those who target the biggest browns with large streamer patterns. The sheer biomass in this section of the river ensures that action remains consistent, even on tougher fishing days.

The primary insect activity mirrors the lower sections of the Green River, providing sustained fishing throughout the year. The prolific blue-winged olives (BWO) hatch during the cooler months of spring and fall, leading to great dry-fly opportunities on overcast days. During the summer, anglers focus on caddis, especially the mother's day hatch, and the tiny, challenging trico hatches in the morning. Midges are the most dependable food source, emerging year-round in the consistent temperatures provided by the dam's release. Furthermore, terrestrial insects like hoppers, ants, and beetles become critically important from mid-July through September, providing thrilling topwater action near the bank edges.

Like all sections of this famous tailwater, wading is highly restrictive due to the river's powerful current and depth, making Section C predominantly a float-only experience. Wading is generally considered safe only in the optimal flow range of 800 to 2,000 CFS, and even then, only in specific, shallow areas. This section is fully floatable, with flow ranges spanning from 800 CFS up to high-water discharges that can peak around 8,000 CFS. Floating allows anglers to effectively work the deep runs and mid-river structure that hold the largest fish, covering the extensive distance necessary to explore this part of the canyon. Always check the USGS gauge ID 09234500 before launching.

Access to Green River Section C is managed through the Uinta-Wasatch-Cache National Forest, and it is usually accessed via drift boat from the Section B take-out point, requiring a full-day commitment to float. While there are designated public access and take-out points, the section feels significantly more remote than the areas immediately below the dam. The nearest major travel hub is Salt Lake City International Airport (SLC), making this a popular destination for traveling anglers seeking the full Green River experience. Anglers should be prepared for a multi-day float trip when combining Sections A, B, and C.

Green River Section C completes the trilogy of world-class tailwater fishing below Flaming Gorge. It delivers high-volume fishing, the chance to land trophy brown and rainbow trout, and a more rugged, scenic canyon float. The consistent flows and insect life make this Utah section a premier fly fishing destination, rounding out an incredible experience for any angler seeking both spectacular scenery and exceptional fish counts.
