Flaming Gorge is a reservoir that earns its name. Red-rock canyon walls dropping into cold, clear Green River water at 6,000 feet in Utah. The lake trout fishery here produces fish in the trophy class, and the kokanee salmon runs in late summer draw trollers from across the West. The Green River tailwater below the dam is a completely separate world-class fly fishing experience. Two elite fisheries, one dam. If you're making a trip to the Colorado Plateau and fish, this is the place to build around.

Flaming Gorge Reservoir Fishing Report
October FishingMonthly fishing report · October patterns and techniques
In October, Flaming Gorge Reservoir experiences cooling water temperatures that typically range from 50 to 58 degrees Fahrenheit, triggering increased feeding activity across the lake's 91-mile length. Fish are becoming more aggressive as they prepare for colder months ahead, and anglers find the shallow-to-mid-depth zones particularly productive this month. The reservoir's dramatic red rock canyons and underwater structure create thermal pockets where fish congregate, making this month one of the most reliable periods for consistent catches.
This month, kokanee salmon and lake trout dominate the action at Flaming Gorge, with cutthroat trout also responding well to angler efforts. Kokanee are most active in the upper portions of the reservoir, particularly around the Sheep Creek arm and near the dam where cooler water persists. Lake trout suspend in the 40 to 80-foot range but move shallower in October, making them accessible from both boat and shore anglers. Cutthroat trout remain active in the shallows and along the rocky points, feeding aggressively in preparation for spawning season. The transition in water temperature this month pushes fish to seek optimal feeding zones rather than retreating to deep structure.
Anglers find success this month using vertical jigging techniques with small spoons and tube jigs in white, orange, and chartreuse colors for lake trout suspended near the main channel. Kokanee respond well to tiny shrimp patterns and spoons trolled at depths of 30 to 50 feet, particularly along the thermocline boundaries. For cutthroat trout, small spinners and live baitfish presentations near the rocky shorelines and submerged points yield consistent results. This month also presents excellent opportunities for shore anglers working the accessible areas around Sheep Creek Marina and the main dam face, where fish are concentrated and feeding actively. Early morning and late afternoon sessions in October tend to produce the best results, as fish are most active during the lower light periods.

Flaming Gorge Reservoir Fishing Strategies by Species
Seasonal patterns and techniques by target species · Verified against official sources
Lake trout, kokanee salmon, brown trout, rainbow trout, and smallmouth bass are the primary sport fish at Flaming Gorge Reservoir, a 42,020-acre Bureau of Reclamation reservoir on the Green River in Daggett County, Utah and Sweetwater County, Wyoming. The dam was completed in 1964. The reservoir sits at approximately 6,000 feet elevation within Flaming Gorge National Recreation Area, administered by the USDA Forest Service. The Green River tailwater immediately below the dam is a designated Utah Blue Ribbon Trout Fishery with large brown trout and rainbow trout for over 28 miles downstream. A Utah or Wyoming fishing license is required depending on which state's waters you are fishing. Verify current regulations including all size limits, bag limits, and any slot limits at wildlife.utah.gov (Utah DWR) and wgfd.wyo.gov (Wyoming Game and Fish) before fishing — Flaming Gorge has historically carried lake-trout slot limits and seasonal kokanee stream closures that must be confirmed before each trip.
Flaming Gorge Reservoir Lake Trout Fishing Report
Lake trout are the trophy species at Flaming Gorge Reservoir and the primary draw for serious anglers who specifically target the fishery. The cold, deep, clear reservoir provides ideal mackinaw habitat, and the fishery produces fish in the 20 to 40-pound range regularly. Verify current lake trout size limits, bag limits, and any slot limits at wildlife.utah.gov (Utah) and wgfd.wyo.gov (Wyoming) before fishing — Flaming Gorge has historically been managed with specific slot restrictions to protect trophy-class lake trout. Lake trout at Flaming Gorge relate to the deep, cold water in the main canyon body of the reservoir, particularly around rocky bottom structure in 60 to 150 feet during summer when the thermocline pushes fish to depth. Jigging large tube jigs and spoons near rocky bottom transitions and submerged points produces lake trout throughout the season. Trolling deep-running crankbaits and swimbaits along the canyon walls and main channel produces consistent fish. Spring and fall bring lake trout shallower as water temperatures moderate, making them accessible in 30 to 60 feet. The Lucerne Valley arm (Manila, UT) and the canyon sections near Dutch John are the most consistent lake trout areas.
Flaming Gorge Reservoir Kokanee Salmon Fishing Report
Kokanee salmon are the schooling species at Flaming Gorge and produce some of the most exciting trolling action in the intermountain West. Fish typically run 12 to 18 inches with occasional larger specimens. Kokanee season at Flaming Gorge peaks June through September before the spawning run. Verify current kokanee regulations at wildlife.utah.gov and wgfd.wyo.gov — seasonal closures apply near tributary streams during the spawning run. Trolling small spinners, wedding ring rigs, and small spoons at 20 to 60 feet in the open water sections of the reservoir produces kokanee throughout the summer. Downriggers or lead core line are standard to reach productive depths. The kokanee school in the thermocline and can be located on a fish finder as tight mid-water column marks. Late summer (August through September) brings the most intense kokanee action before spawning behavior begins. The Sheep Creek arm and the open main lake basin are consistent kokanee areas.
Flaming Gorge Reservoir Brown Trout Fishing Report
Brown trout are present throughout Flaming Gorge Reservoir and grow to trophy size in the productive deep water. Brown trout relate more to the canyon shoreline and tributary arms than lake trout do, preferring the near-shore structure in 15 to 40 feet. Verify current size and bag limits at wildlife.utah.gov and wgfd.wyo.gov before fishing. The canyon wall areas and the cove structure near tributary inflows produce brown trout on crankbaits and larger streamers fished along the rocky margins. Dawn and dusk produce the most surface-oriented brown trout activity. The Green River inflow at the upper end of the reservoir concentrates brown trout during periods of active water flow. The tailwater immediately below the dam is a completely separate world-class brown trout fishery managed under Utah's Blue Ribbon designation.
Flaming Gorge Reservoir Rainbow Trout Fishing Report
Rainbow trout are stocked in Flaming Gorge Reservoir by Utah DWR and provide accessible trout fishing throughout the reservoir, particularly near the boat ramps and shoreline access areas. Rainbow trout are more mobile than lake trout and can be found throughout the water column in spring and fall when temperatures are suitable. Verify current regulations at wildlife.utah.gov before fishing. Trolling small spinners and spoons at 10 to 30 feet produces rainbow trout in the shallower canyon arms and the Lucerne Valley area during spring and fall. Shore fishing near the Dutch John boat ramp and the Lucerne Valley Marina area with PowerBait or small spinners produces rainbow trout for walk-in anglers. Summer rainbow trout seek cooler water in 30 to 50 feet as surface temperatures warm.
Flaming Gorge Reservoir Smallmouth Bass Fishing Report
Smallmouth bass thrive in the clear, rocky canyon structure of Flaming Gorge Reservoir, particularly in the shallower canyon arms and the rocky shoreline areas in the Utah portion of the lake. The clear water and rocky structure are ideal smallmouth habitat. Verify current bass regulations at wildlife.utah.gov and wgfd.wyo.gov before fishing. Tube jigs, drop shots, and small crankbaits worked along the rocky canyon wall base and submerged points in 5 to 20 feet produce consistent smallmouth throughout the warm months. Spring smallmouth are the most accessible as fish move shallow to spawn on gravel areas adjacent to the canyon walls. The Lucerne Valley area and the canyon arms near Manila, Utah hold the best smallmouth habitat. Summer smallmouth hold slightly deeper along the canyon walls and remain active through fall.
If you haven't replaced your braided line in a season or two, now's the time. Braid holds up better than mono, but abrasion from wood and rock adds up. Reaction Tackle is one of my favorite places to order from.

About Flaming Gorge Reservoir
Flaming Gorge Reservoir is a Bureau of Reclamation impoundment on the Green River that delivers an unusual combination: a nationally recognized lake trout and kokanee salmon fishery in canyon country at 6,000 feet, paired with one of the most acclaimed fly fishing tailwaters in the West immediately below the dam. 42,020 acres, spanning Utah and Wyoming, Flaming Gorge National Recreation Area administered by the USDA Forest Service. The red-rock canyon walls, cold clear water, and the scale of the place make this a fishing destination with no close equivalent in the intermountain West.
Two fisheries in one location. Flaming Gorge Reservoir and the Green River tailwater below the dam are two separate world-class fishing experiences sharing a single address. The reservoir produces trophy lake trout and kokanee salmon for trollers and jig fishers. The 28-mile Green River tailwater designated as a Utah Blue Ribbon Trout Fishery produces large wild brown trout and rainbow trout for fly anglers. Planning to fish both in a single trip is the right approach.
Regulations vary by state and season. The reservoir spans Utah and Wyoming, and each state manages its own side. Utah fishing license required for Utah waters; Wyoming license required for Wyoming waters (northern portion of the lake). Flaming Gorge has historically carried lake trout slot limits and trophy fish protections, and kokanee regulations include seasonal stream closures during spawning. Verify current regulations from Utah DWR (wildlife.utah.gov) and Wyoming Game and Fish (wgfd.wyo.gov) before every trip — regulations have been adjusted multiple times as the fishery has evolved.
Lake size and location. Flaming Gorge Reservoir covers approximately 42,020 acres at full pool with a maximum depth of approximately 436 feet. The reservoir sits at approximately 6,000 feet elevation. Bureau of Reclamation completed the dam in 1964. Dutch John, Utah (adjacent to the dam) and Manila, Utah (Lucerne Valley Marina area) are the primary access points on the Utah side. Buckboard Marina serves the Wyoming (northern) end. Rock Springs, Wyoming is the nearest larger city to the north. Vernal, Utah is the nearest larger city to the south.
NRA access fees. Flaming Gorge is within a USDA Forest Service National Recreation Area. Day-use and boat launch fees apply. America the Beautiful/Interagency Annual Pass is accepted. Contact the Ashley National Forest for current fee information at fs.usda.gov/ashley.
