505-acre reservoir near La Plata County. The lake tops out around 188 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 462 acres wrapped in 6.2 miles of bank. A middling shoreline index (2.1) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 21% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 2.7 mi with a 0.4-mi widest point. La Plata County claims this one. Andrews Lake sits 23 mi north — the closest neighbouring chart.
When the water first warms, kokanee slide up into 10 to 30 ft. Summer is a 30 to 70 ft game here, winter a 20 to 80 ft one. Start at Break off the point. It's a drop-off holding about 85 ft of water and rates good come winter. The feeding windows run early morning. Keep a dodger + pink/orange squid on downrigger or a kokanee bug + corn rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | Deep basin (160 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Deep basin (160 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | open water | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 20 to 80 ft | dawn | Break off the point (85 ft) | Small glow jig + corn or maggot, Tiny spoon |
Start shallow in spring: brown trout sit in 3 to 25 ft that time of year. Summer pushes them deeper, 25 to 60 ft, and winter fish settle into 5 to 35 ft. The spot to know is Main-lake point, a point in about 47 ft of water that rates prime for brown trout in summer. Warm-month bites cluster around after dark and early morning. 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 | open water | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 25 to 60 ft | night & dawn | Main-lake point (47 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | open water | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (85 ft) | Jigging spoon, Small stickbait (slow) |
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores good in spring. Best bite is 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 | Shallow bay flat (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (85 ft) | Jigging spoon, Tube jig (white) |
Spring splake on Lemon Reservoir hold shallow, usually 5 to 25 ft. They move out to 25 to 60 ft in summer and finish the year down in 10 to 45 ft. Put Main-lake point first on the milk run — a point near 47 ft that grades good for summer. The feeding windows run early morning and the evening. The summer box starts with a trolled spoon at the thermocline or a white tube jig (deep).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | open water | Small casting spoon (gold/orange), Inline spinner |
