2,087-acre lake near Rocky Mountain House. The lake tops out around 7 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
On the chart, Cow Lake draws 2,083 acres inside 8.8 miles of shoreline. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Figure 2.9 mi of water from one end to the other, 1.6 mi at the beam. You'll find it in Division No. 9. Closest neighbour on DepthScout: Mitchell Lake, 4 mi south of here.
In spring, brook trout run shallow here, mostly 1 to 7 ft. Summer keeps them at 2 to 7 ft, and they winter in 1 to 7 ft. Deep basin is the standout, a deep basin at roughly 7 ft, rated prime for summer brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 7 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 2 to 7 ft | dawn & dusk | Deep basin (7 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 7 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 7 ft | dawn | Deep basin (7 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for brown trout tight to the bank in 1 to 7 ft. Through summer count on 2 to 7 ft; the winter hold is 1 to 7 ft. Start at Break off the point. It's a drop-off holding about 4 ft of water and rates prime come summer. Prime time lands in after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 7 ft | dawn & dusk | Main-lake point (2 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 2 to 7 ft | night & dawn | Break off the point (4 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 1 to 7 ft | dusk & dawn | Main-lake point (2 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 1 to 7 ft | dawn | Break off the point (4 ft) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: northern pike sit in 2 to 7 ft that time of year. They don't go far with the seasons — 2 to 7 ft covers summer, 2 to 7 ft covers winter. Top water on the chart: Shallow bay flat, a weed flat in the 2 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 7 ft | dawn & dusk | Shallow bay flat (2 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 7 ft | midday & dawn | Shallow bay flat (2 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 7 ft | midday | Shallow bay flat (2 ft) | Tip-ups, Large jigging spoon |
Spring puts rainbow trout in skinny water — 2 to 7 ft is the zone. Summer fish stay in 2 to 7 ft, and winter fish hold in 1 to 7 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 4 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft | dawn & dusk | Main-lake point (2 ft) | Inline spinner (silver), Small spoon |
| Summer | 2 to 7 ft | dawn & dusk | Break off the point (4 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 2 to 7 ft | dawn & dusk | Main-lake point (2 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 1 to 7 ft | dawn | Break off the point (4 ft) | Jigging spoon, Tube jig (white) |
Come spring, look for yellow perch tight to the bank in 2 to 7 ft. Through summer count on 2 to 7 ft; the winter hold is 2 to 7 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 2 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 7 ft | dawn | Deep basin (7 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 7 ft | midday | Deep basin (7 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 7 ft | midday & dawn | Deep basin (7 ft) | Tungsten jig + spikes, Rattle spoon (small) |
