800-acre reservoir near Laramie Region. The lake tops out around 130 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Rob Roy Reservoir runs 799 acres with 11.8 miles of edge. The 3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 41% of the surface on the model — that's where the groceries are. The basin spans about 2.1 mi end to end and 1.8 mi across at its widest. You'll find it in Albany County. Closest neighbour on DepthScout: Silver Run Lake, 8 mi north of here.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. The spot to know is Shallow bay flat, a weed flat in about 6 ft of water that rates good for brook trout in spring. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season brown trout use the shallows, holding in 3 to 25 ft. Expect a summer slide to 25 to 60 ft, then a winter hold in 5 to 35 ft. Put Break off the point first on the milk run — a drop-off near 59 ft that grades prime for summer. In summer the feeding windows fall in after dark and early morning. Tie on a spoon at the thermocline or a deep stickbait (night) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (33 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 25 to 60 ft | night & dawn | Break off the point (59 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (33 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (59 ft) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: kokanee sit in 10 to 30 ft that time of year. Summer pushes them deeper, 30 to 70 ft, and winter fish settle into 20 to 80 ft. The spot to know is Break off the point, a drop-off in about 59 ft of water that rates prime for kokanee in summer. Warm-month bites cluster around early morning. Throw a dodger + pink/orange squid on downrigger or a kokanee bug + corn until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | Deep basin (111 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Break off the point (59 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 (59 ft) | Small glow jig + corn or maggot, Tiny spoon |
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: Main-lake point, a point in the 33 ft range, prime in fall. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| 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 (33 ft) | Dodger + spoon (deep troll), Flutter spoon |

The spot to know is Break off the point, a drop-off in about 59 ft of water that rates prime for splake in summer. Plan around early morning and the evening in the warm months. Summer baits: a trolled spoon at the thermocline or a white tube jig (deep) gets it done.
