2,064-acre lake near Lake County. The lake tops out around 95 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 2,377 acres wrapped in 17.5 miles of bank, with 4 islands in the mix. A development index of 2.6 means a maze of bays and points: far more casting targets than a round bowl of the same size. 39% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 4.3 mi of water from one end to the other, 1.7 mi at the beam. It sits in Lake County. If the bite dies, Clear Creek Reservoir is 6 mi to the southeast.
Start shallow in spring: brown trout sit in 3 to 25 ft that time of year. Warm water sends them out to 25 to 60 ft; cold water stacks them in 5 to 35 ft. Top water on the chart: Break off the point, a drop-off in the 43 ft range, prime in summer. Fish it in after dark and early morning and you'll meet the bite. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (24 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 25 to 60 ft | night & dawn | Break off the point (43 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (24 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (43 ft) | Jigging spoon, Small stickbait (slow) |
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 29 to 95 ft, then a winter hold in 20 to 80 ft. Put Deep basin first on the milk run — a deep basin near 81 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (24 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 29 to 95 ft | dawn | Deep basin (81 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (24 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (81 ft) | White tube jig, Airplane jig |
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Start at Main-lake point. It's a point holding about 24 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (24 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (24 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (43 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: cutthroat trout sit in 3 to 15 ft that time of year. Warm water sends them out to 10 to 35 ft; cold water stacks them in 10 to 40 ft. Top water on the chart: Main-lake point, a point in the 24 ft range, prime in fall. Fish it in early morning and the evening and you'll meet the bite. Throw a trolled spoon (small) or an inline spinner until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | open water | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Main-lake point (24 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (24 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (43 ft) | Small jigging spoon, Marabou jig |
