1,315-acre reservoir near Grand County. The lake tops out around 24 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Species by species, here's what the data says the year looks like.
Drawn out, this is 1,280 acres of water rimmed by 11.6 miles of bank — 8 islands included. That shoreline is heavily fingered (development index 2.3) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 81% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 3.1 mi of water from one end to the other, 1 mi at the beam. You'll find it in Grand County.

Spring brown trout on Shadow Mountain Reservoir hold shallow, usually 3 to 24 ft. Depth-wise the year is flat: 7 to 24 ft in summer, 3 to 24 ft once it turns cold. The chart's best answer is Break off the point — drop-off, 11 ft, prime for summer. Prime time lands in after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 24 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 7 to 24 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (11 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 4 to 24 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 3 to 24 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (11 ft) | Jigging spoon, Small stickbait (slow) |
Spring cutthroat trout on Shadow Mountain Reservoir hold shallow, usually 3 to 15 ft. By summer they slide out to 7 to 24 ft, and by winter most fish are in 6 to 24 ft. The chart's best answer is Break off the point — drop-off, 11 ft, prime for summer. Prime time lands in 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 | Main-lake point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 7 to 24 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Break off the point (11 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 24 ft chart-limited; documented 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 6 to 24 ft chart-limited; documented 10 to 40 ft | dawn | Break off the point (11 ft) | Small jigging spoon, Marabou jig |
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Summer pushes them deeper, 6 to 24 ft, and winter fish settle into 5 to 24 ft. The spot to know is Break off the point, a drop-off in about 11 ft of water that rates prime for rainbow trout in winter. Warm-month bites cluster around early morning and the evening. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.

| Winter | 5 to 24 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (11 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: kokanee in 7 to 24 ft. The depth story barely changes: 7 to 24 ft through summer, 6 to 24 ft in winter. Top water on the chart: Deep basin, a deep basin in the 20 ft range, prime in spring. Time it for early morning. Summer baits: a dodger + pink/orange squid on downrigger or a kokanee bug + corn gets it done.

The spring pattern is a shallow one: lake trout in 6 to 24 ft. The depth story barely changes: 7 to 24 ft through summer, 6 to 24 ft in winter. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for lake trout in summer. Plan around early morning in the warm months. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
