Rating depth structure for burbot.
Recent public catches load as you reach this section.
16,151-acre lake near Muriel Lake. The lake tops out around 35 ft. The depth chart comes from Alberta Geological Survey bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 16,115 acres, worked by 40.5 miles of shoreline — 2 islands included. The 2.3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 30% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 7.8 mi, about 6.8 mi across. Division No. 12 claims this one. Jessie Lake sits 7 mi north — the closest neighbouring chart.
Spring burbot on Muriel Lake hold shallow, usually 11 to 35 ft. Depth-wise the year is flat: 11 to 35 ft in summer, 9 to 35 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 34 ft that grades prime for spring. The feeding windows run after dark and midday. The summer box starts with a heavy jig + cut bait.
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 | 11 to 35 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (34 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 11 to 35 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (34 ft) | Heavy jig + cut bait |
| Fall | 11 to 35 ft chart-limited; documented 30 to 80 ft | night & dusk | Deep basin (34 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 9 to 35 ft chart-limited; documented 15 to 60 ft | night & dusk | Deep basin (34 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
In spring, lake whitefish run shallow here, mostly 11 to 35 ft. Summer keeps them at 11 to 35 ft, and they winter in 11 to 35 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 34 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 11 to 35 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (25 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 11 to 35 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (34 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (25 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 11 to 35 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (34 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Sharp break 1 (9 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Sharp break 1 (9 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Weed flat (4 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 15 to 35 ft, wintering in 11 to 35 ft. Top water on the chart: Break off the point, a drop-off in the 25 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Shoreline point 2 (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (25 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 11 to 35 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (25 ft) | Jigging rap, Jig + big minnow |
| Winter | 11 to 35 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (34 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. Back-bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (25 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (34 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (34 ft) | Tungsten jig + spikes, Rattle spoon (small) |
