6,425-acre lake in Manitoba. The lake tops out around 13 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, St Andrew Lake runs 6,578 acres with 25 miles of edge. That shoreline is heavily fingered (development index 2.2) — bays, points and pockets everywhere, which multiplies the fishable edge. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 8.3 mi end to end and 2.6 mi across at its widest. The water lies in Division No. 19. For a second option, Lake Winnipeg lies 35 mi northwest.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 4 to 13 ft, then a winter hold in 4 to 13 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 13 ft | dawn | Deep basin (13 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 13 ft | midday | Deep basin (13 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 13 ft | midday & dawn | Deep basin (13 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring walleye on St Andrew Lake hold shallow, usually 3 to 13 ft. Depth-wise the year is flat: 4 to 13 ft in summer, 4 to 13 ft once it turns cold. Put Break off the point first on the milk run — a drop-off near 11 ft that grades prime for fall. The feeding windows run the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 13 ft | dusk & dawn | Gravel shoal (2 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 4 to 13 ft | dusk & dawn | Break off the point (11 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 4 to 13 ft | dusk & night | Break off the point (11 ft) | Jigging rap, Jig + big minnow |
| Winter | 4 to 13 ft | dusk & dawn | Deep basin (13 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 4 to 13 ft, and winter fish settle into 4 to 13 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 4 to 13 ft | dawn & dusk | Break off the point (11 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 13 ft | midday & dawn | Break off the point (11 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 13 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
