38,880-acre reservoir near Manila. The lake tops out around 436 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Flaming Gorge Reservoir runs 40,669 acres with 390.3 miles of edge — 2 islands included. An index of 13.8 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 43% of the surface on the model — that's where the groceries are. Call it 41.5 mi long by 13.9 mi wide at the broadest reach. The water lies in Sweetwater County. Closest neighbour on DepthScout: Green River (Flaming Gorge), 25 mi southeast of here.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 50 to 120 ft, and winter fish settle into 20 to 80 ft. Rock reef is the standout, a rock pile at roughly 9 ft, rated prime for fall lake trout. Time it for early morning. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Rock reef (9 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Offshore hump (73 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Rock reef (9 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Offshore hump (73 ft) | White tube jig, Airplane jig |
Spring puts kokanee in skinny water — 10 to 30 ft is the zone. Warm water sends them out to 30 to 70 ft; cold water stacks them in 20 to 80 ft. Creek inflow is the standout, an inflow / creek mouth at roughly 8 ft, rated prime for fall kokanee. Plan around early morning in the warm months. A dodger + pink/orange squid on downrigger or a kokanee bug + corn covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | Deep basin (371 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Offshore hump (73 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | Creek inflow (8 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 20 to 80 ft | dawn | Offshore hump (73 ft) | Small glow jig + corn or maggot, Tiny spoon |
The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 20 to 45 ft. Top water on the chart: Rock reef, a rock pile in the 9 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Rock reef (9 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Rock reef (9 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Shoreline point (9 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (196 ft) | Blade bait, Hair jig |
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. Spring rainbow trout concentrate at Creek inflow, a prime-rated inflow / creek mouth around 8 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Creek inflow (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Creek inflow (8 ft) | Dodger + spoon (deep troll), Flutter spoon |

When the water first warms, brown trout slide up into 3 to 25 ft. Summer is a 25 to 60 ft game here, winter a 5 to 35 ft one. Start at Creek inflow. It's an inflow / creek mouth holding about 8 ft of water and rates prime come spring. The feeding windows run after dark and early morning. Keep a spoon at the thermocline or a deep stickbait (night) rigged through the warm months.
