37-acre lake near Rocky Mountain House. The lake tops out around 20 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
Mitchell Lake maps at 37 acres behind 0.9 miles of shoreline. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. The shallow band under 15 ft claims about 83% of the surface — that's where the groceries are. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. It sits in Division No. 9. Strubel Lake sits 1 mi south — the closest neighbouring chart.
Spring brook trout on Mitchell Lake hold shallow, usually 2 to 15 ft. By summer they slide out to 6 to 20 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Deep basin — deep basin, 20 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (10 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 6 to 20 ft | dawn & dusk | Deep basin (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (10 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Deep basin (20 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring puts brown trout in skinny water — 2 to 20 ft is the zone. Summer fish stay in 6 to 20 ft, and winter fish hold in 3 to 20 ft. Break off the point is the standout, a drop-off at roughly 19 ft, rated prime for summer brown trout. Plan around after dark and early morning in the warm months. A spoon at the thermocline or a deep stickbait (night) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 20 ft | dawn & dusk | Main-lake point (10 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 6 to 20 ft | night & dawn | Break off the point (19 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 3 to 20 ft | dusk & dawn | Main-lake point (10 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 3 to 20 ft | dawn | Break off the point (19 ft) | Jigging spoon, Small stickbait (slow) |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Even in summer they hold at 5 to 20 ft; winter keeps them in 4 to 20 ft. Put Break off the point first on the milk run — a drop-off near 19 ft that grades prime for winter. 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 20 ft | dawn & dusk | Main-lake point (10 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 20 ft | dawn & dusk | Break off the point (19 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 6 to 20 ft | dawn & dusk | Main-lake point (10 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 20 ft | dawn | Break off the point (19 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 6 to 20 ft; cold water stacks them in 6 to 20 ft. Top water on the chart: Shallow bay flat, a weed flat in the 5 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
