Service Creek to Clarno. The West's best smallmouth float, plus a wild steelhead run. The river tops out around 8 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Here's the year, species by species, as the scoring engine sees it.
On the chart, John Day River draws 1,738 acres inside 89.8 miles of shoreline. That shoreline is heavily fingered (development index 15.4) — bays, points and pockets everywhere, which multiplies the fishable edge. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 24.6 mi end to end and 9.5 mi across at its widest. The water lies in Wheeler County. Closest neighbour on DepthScout: Deschutes River (Lower), 45 mi west of here.
In spring, smallmouth bass run shallow here, mostly 2 to 8 ft. Summer keeps them at 2 to 8 ft, and they winter in 2 to 8 ft. Riffle & run (mile 24.3) is the standout, a rock pile at roughly 3 ft, rated prime for spring smallmouth bass. Time it for early morning and the evening. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dawn & dusk | Riffle & run (mile 24.3) (3 ft) | Ned rig, Tube jig |
| Summer | 2 to 8 ft | dawn & dusk | Riffle & run (mile 24.3) (3 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 2 to 8 ft | midday & dawn | Riffle & run (mile 24.3) (3 ft) | Jerkbait, Blade bait |
| Winter | 2 to 8 ft | midday | Current seam (mile 41.7) (4 ft) | Blade bait, Hair jig |
Early season steelhead use the shallows, holding in 1 to 8 ft. Even in summer they hold at 1 to 8 ft; winter keeps them in 2 to 8 ft. The chart's best answer is Current seam (mile 41.7) — current seam, 4 ft, prime for summer. Best bite is early morning and the evening. Tie on an orange dodger + fly high in the column or a thin spoon off boards and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | dawn & dusk | Current seam (mile 41.7) (4 ft) | Small spoon or spinner at the mouths, Jig + waxworm under float |
| Summer | 1 to 8 ft | dawn & dusk | Current seam (mile 41.7) (4 ft) | Orange dodger + fly high in the column, Thin spoon off boards |
| Fall | 1 to 8 ft | dawn & dusk | Current seam (mile 41.7) (4 ft) | Spinner (silver/blue), Casting spoon |
| Winter | 2 to 8 ft | midday | Current seam (mile 41.7) (4 ft) | Float jig (black/purple), Bead rig |
Spring puts channel catfish in skinny water — 2 to 8 ft is the zone. Summer fish stay in 2 to 8 ft, and winter fish hold in 2 to 8 ft. Summer channel catfish concentrate at Outside-bend hole (mile 0.6), a prime-rated creek channel around 6 ft. Warm-month bites cluster around after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk | Outside-bend hole (mile 0.6) (6 ft) | |
| Summer | 2 to 8 ft | night & dusk | Outside-bend hole (mile 0.6) (6 ft) | |
| Fall | 2 to 8 ft | dusk | Outside-bend hole (mile 0.6) (6 ft) | |
| Winter | 2 to 8 ft | midday | Outside-bend hole (mile 0.6) (6 ft) |
