2,189-acre lake near Whiteshell Provincial Park. 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. Species by species, here's what the data says the year looks like.
On the chart, Brereton Lake draws 2,214 acres inside 16.5 miles of shoreline, broken up by 3 islands. With a shoreline index of 2.5, this water is all arms and coves — edge habitat well beyond its acreage. 79% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 3.5 mi of water from one end to the other, 1.8 mi at the beam. You'll find it in Division No. 1. The nearest mapped water is Jessica Lake, 8 mi to the north.
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 7 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (7 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (7 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (7 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (7 ft) | Tip-ups, Large jigging spoon |
Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 6 to 20 ft, then a winter hold in 6 to 20 ft. Put Break off the point first on the milk run — a drop-off near 16 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
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 | 4 to 15 ft | dusk & dawn | Creek inflow (2 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 6 to 20 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (16 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 20 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (16 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 20 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (20 ft) | Jigging spoon + minnow head, Rattle bait |
Spring yellow perch on Brereton Lake hold shallow, usually 3 to 12 ft. They move out to 6 to 20 ft in summer and finish the year down in 6 to 20 ft. Put Shallow bay flat first on the milk run — a weed flat near 7 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (7 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 20 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts crappie in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 6 to 20 ft; cold water stacks them in 6 to 20 ft. Old creek channel is the standout, a creek channel at roughly 8 ft, rated prime for fall crappie. Plan around early morning and the evening in the warm months. A jig trolled/spider-rigged or a small crankbait (trolled) covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (7 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 6 to 20 ft chart-limited; documented 10 to 25 ft | dawn & dusk | Old creek channel (8 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Old creek channel (8 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 6 to 20 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (20 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Start shallow in spring: kokanee sit in 6 to 20 ft that time of year. They don't go far with the seasons — 6 to 20 ft covers summer, 5 to 20 ft covers winter. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for kokanee in spring. Warm-month bites cluster around early morning. Throw a dodger + pink/orange squid on downrigger or a kokanee bug + corn until the fish tell you otherwise.
