1,645-acre lake in Rainy River District, Ontario. The lake tops out around 150 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Sandbeach Lake runs 1,652 acres with 11.5 miles of edge. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 16% of the water is 15 ft or less, the band where the food chain lives. Call it 3.5 mi long by 1.7 mi wide at the broadest reach. The water lies in Rainy River District. For a second option, Pettit Lake lies 3 mi west.
The spring pattern is a shallow one: lake trout in 10 to 40 ft. As the season builds they drop to 50 to 120 ft, wintering in 20 to 80 ft. Top water on the chart: Break off the point, a drop-off in the 96 ft range, prime in summer. Time it for early morning. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (1 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Break off the point (96 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (1 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (96 ft) | White tube jig, Airplane jig |
Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. Expect a summer slide to 40 to 90 ft, then a winter hold in 25 to 70 ft. Start at Feeding flat. It's a feeding flat holding about 35 ft of water and rates prime come spring. Prime time lands in early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Feeding flat (35 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Break off the point (96 ft) | Blade bait vertical, Small jigging spoon |

Come spring, look for cisco (lake herring) tight to the bank in 10 to 40 ft. Expect a summer slide to 40 to 80 ft, then a winter hold in 20 to 60 ft. Start at Deep basin. It's a deep basin holding about 150 ft of water and rates good come spring. Prime time lands in early morning. A vertical flutter spoon (small) or a drop-shot micro plastic is the honest summer answer here.

|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (150 ft) | Small silver spoon, Tiny swim jig (white) |

Spring walleye on Sandbeach Lake hold shallow, usually 4 to 15 ft. They move out to 15 to 35 ft in summer and finish the year down in 20 to 40 ft. Put Feeding flat first on the milk run — a feeding flat near 35 ft that grades good for summer. 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 | 4 to 15 ft | dusk & dawn | Main-lake point (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Feeding flat (35 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |

Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Put Shallow bay flat first on the milk run — a feeding flat near 1 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 (1 ft) | Small jig + curly tail, Perch-pattern micro crank |

In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. Shallow bay flat is the standout, a feeding flat at roughly 1 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 (1 ft) | #5 inline spinner, Spoon (red/white) |
