934-acre lake in Alberta. The lake tops out around 6 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
Cache Lake maps at 932 acres behind 6.2 miles of shoreline. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Figure 2 mi of water from one end to the other, 1.1 mi at the beam. Division No. 13 claims this one. Its nearest charted neighbour, Skeleton Lake, is 18 mi to the northeast.
Start shallow in spring: yellow perch sit in 2 to 6 ft that time of year. They don't go far with the seasons — 2 to 6 ft covers summer, 2 to 6 ft covers winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
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 | 2 to 6 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 6 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 6 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 6 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 6 ft. Through summer count on 2 to 6 ft; the winter hold is 2 to 6 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft chart-limited; documented 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 6 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 6 ft chart-limited; documented 6 to 18 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 6 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Spring puts walleye in skinny water — 2 to 6 ft is the zone. Summer fish stay in 2 to 6 ft, and winter fish hold in 2 to 6 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 2 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.

| Winter | 2 to 6 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (5 ft) | Jigging spoon + minnow head, Rattle bait |
Cache Lake carries 6 mapped structure features, topping out (or rather bottoming out) at Secondary point, about 6 ft down.
Season dates, license requirements, and size and bag limits for Alberta waters are set by the Alberta fishing regulations — and special regulations can apply to Cache Lake specifically, so confirm the current rules before you fish.

Cache Lake is about 6 ft (2 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target yellow perch, northern pike, walleye on Cache Lake. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch in spring. The interactive chart above rates every spot for each species and season.
For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Cache Lake is regulated by the Alberta fishing regulations. Check the official Alberta regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
