1,006-acre reservoir near Cassia. The lake tops out around 19 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 889 acres wrapped in 12.3 miles of bank. A development index of 2.9 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 95% of the water is 15 ft or less as modeled, the band where the food chain lives. Tip to tip the water measures near 4.4 mi with a 1.5-mi widest point. It sits in Cassia County. Cedar Creek Reservoir sits 49 mi west — the closest neighbouring chart.
Early season rainbow trout use the shallows, holding in 5 to 19 ft. Even in summer they hold at 5 to 19 ft; winter keeps them in 4 to 19 ft. Put Main-lake point first on the milk run — a point near 8 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 19 ft | dawn | Deep basin (16 ft) | Jigging spoon, Tube jig (white) |
In spring, steelhead run shallow here, mostly 3 to 19 ft. Summer keeps them at 2 to 19 ft, and they winter in 4 to 15 ft. Summer steelhead concentrate at Deep basin, a prime-rated deep basin around 16 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than an orange dodger + fly high in the column or a thin spoon off boards most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Small spoon or spinner at the mouths, Jig + waxworm under float |
| Summer | 2 to 19 ft | dawn & dusk | Deep basin (16 ft) | Orange dodger + fly high in the column, Thin spoon off boards |
| Fall | 3 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Spinner (silver/blue), Casting spoon |
| Winter | 4 to 15 ft | midday | Deep basin (16 ft) | Float jig (black/purple), Bead rig |
When the water first warms, chinook salmon slide up into 2 to 19 ft. There's no big seasonal slide here — summer means 6 to 19 ft, winter 6 to 19 ft. If you only fish one area, make it Deep basin: a deep basin around 16 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a flasher + fly (green/white) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 19 ft | dawn & dusk | Deep basin (16 ft) | Trolled spoon (orange/gold), Stickbait off planer boards |
| Summer | 6 to 19 ft | dawn & dusk | Deep basin (16 ft) | Flasher + fly (green/white), Magnum spoon on downrigger |
| Fall | 4 to 19 ft | dawn & dusk | Main-lake point (8 ft) | J-plug (glow), Flasher + fly |
| Winter | 6 to 19 ft | midday | Deep basin (16 ft) | Small spoon on a slow troll, Stickbait deep |
When the water first warms, coho salmon slide up into 2 to 19 ft. There's no big seasonal slide here — summer means 6 to 19 ft, winter 6 to 19 ft. Start at Deep basin. It's a deep basin holding about 16 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a dodger + fly or a medium spoon above the thermocline rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 6 to 19 ft | dawn & dusk | Deep basin (16 ft) | Dodger + fly, Medium spoon above the thermocline |
| Fall | 4 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Spinner (chartreuse) |
| Winter | 6 to 19 ft | midday | Deep basin (16 ft) | Small spoon, slow troll |
Spring puts walleye in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 6 to 19 ft; cold water stacks them in 6 to 19 ft. Deep basin is the standout, a deep basin at roughly 16 ft, rated prime for winter walleye. Plan around the evening and early morning in the warm months. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 6 to 19 ft | dusk & dawn | Main-lake point (8 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 19 ft | dusk & night | Main-lake point (8 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 19 ft | dusk & dawn | Deep basin (16 ft) | Jigging spoon + minnow head, Rattle bait |
When the water first warms, channel catfish slide up into 3 to 12 ft. Summer is a 6 to 19 ft game here, winter a 6 to 19 ft one. Start at Deep basin. It's a deep basin holding about 16 ft of water and rates prime come winter. The feeding windows run after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (3 ft) | |
| Summer | 6 to 19 ft | night & dusk | Deep basin (16 ft) | |
