1,263-acre lake near Yakima County. The lake tops out around 89 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Bumping Lake runs 1,263 acres with 6.8 miles of edge. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. About 26% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 3 mi long by 1 mi wide at the broadest reach. The water lies in Yakima County. The nearest mapped water is Packwood Lake, 22 mi to the southwest.
Spring cutthroat trout on Bumping Lake hold shallow, usually 3 to 15 ft. They move out to 10 to 35 ft in summer and finish the year down in 10 to 40 ft. Put Boulder Creek inflow first on the milk run — an inflow / creek mouth near 2 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a trolled spoon (small) or an inline spinner.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Boulder Creek inflow (2 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Deep Creek inflow (16 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Deep Creek inflow (16 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Deep Creek inflow (16 ft) | Small jigging spoon, Marabou jig |
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Top water on the chart: Deep Creek inflow, an inflow / creek mouth in the 16 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Deep Creek inflow (16 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Deep Creek inflow (16 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Deep Creek inflow (16 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Deep Creek inflow (16 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. The spot to know is Boulder Creek inflow, an inflow / creek mouth in about 2 ft of water that rates prime for brook trout in spring. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Boulder Creek inflow (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep Creek inflow (16 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Boulder Creek inflow (2 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Deep Creek inflow (16 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: kokanee in 10 to 30 ft. Midsummer fish sit out in 30 to 70 ft before dropping to 20 to 80 ft for winter. The spot to know is Deep Creek inflow, an inflow / creek mouth in about 16 ft of water that rates prime for kokanee in fall. Plan around early morning in the warm months. Summer baits: a dodger + pink/orange squid on downrigger or a kokanee bug + corn gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | Deep Creek inflow (16 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Break off the point (56 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | Deep Creek inflow (16 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 20 to 80 ft | dawn | Deep basin (88 ft) | Small glow jig + corn or maggot, Tiny spoon |
