8,829-acre lake near Canyon. The lake tops out around 48 ft. The depth chart comes from U.S. Bureau of Reclamation, Technical Service Center bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 6,912 acres of water rimmed by 21.7 miles of bank. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 21% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 7.9 mi with a 2.6-mi widest point. You'll find it in Canyon County. Closest neighbour on DepthScout: Succor Creek Reservoir, 29 mi southwest of here.
Early season cutthroat trout use the shallows, holding in 3 to 15 ft. Expect a summer slide to 10 to 35 ft, then a winter hold in 10 to 40 ft. Put Break off the point first on the milk run — a drop-off near 18 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a trolled spoon (small) or an inline spinner and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Sharp break 2 (14 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (18 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Break off the point (18 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (18 ft) | Small jigging spoon, Marabou jig |
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 18 ft range, good in winter. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.

Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 20 to 45 ft. Sharp break 1 is the standout, a drop-off at roughly 25 ft, rated prime for winter smallmouth bass. Plan around early morning and the evening in the warm months. A drop shot (goby/minnow) or a ned rig covers the summer program.

|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (18 ft) | Drop shot (goby/minnow), Ned rig |

In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 15 to 35 ft for winter. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 10 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.

|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (10 ft) | Spinnerbait, Chatterbait |
