62-acre lake in Rainy River District, Ontario. The lake tops out around 13 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 62 acres of water rimmed by 1.5 miles of bank. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. End to end it runs roughly 0.5 mi, about 0.4 mi across. The water lies in Rainy River District. The nearest mapped water is Caribus Lake, 2 mi to the southwest.
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.
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 | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 13 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (11 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 13 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (11 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 13 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (11 ft) | Tungsten jig + spikes, Rattle spoon (small) |
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 chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 13 ft chart-limited; documented 6 to 18 ft | midday & dawn | Break off the point (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 13 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Structure-wise the chart holds 5 features, led in depth by Deep basin at roughly 11 ft.

Olympia Lake is about 13 ft (4 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target yellow perch, northern pike on Olympia Lake.
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. Open the map above to see every rated 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.
