Rating depth structure for brook trout.
Recent public catches load as you reach this section.
21-acre lake in Algoma District, Ontario. The lake tops out around 7 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. What the data behind the map says about each species, season by season:
The drawn water covers 21 acres wrapped in 1.2 miles of bank. A middling shoreline index (1.8) gives it some bays to work without being a maze. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Figure 0.5 mi of water from one end to the other. Algoma District claims this one. If the bite dies, Rockey Lake is 1 mi to the southeast.
When the water first warms, brook trout slide up into 1 to 7 ft. There's no big seasonal slide here — summer means 2 to 7 ft, winter 1 to 7 ft. Start at Deep basin. It's a deep basin holding about 6 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
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 | 1 to 7 ft chart-limited; documented 2 to 15 ft | dawn & dusk | Main-lake point (7 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 2 to 7 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (6 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 7 ft chart-limited; documented 2 to 15 ft | midday & dawn | Main-lake point (7 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 7 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring puts rock bass in skinny water — 1 to 7 ft is the zone. Summer fish stay in 2 to 7 ft, and winter fish hold in 2 to 7 ft. Main-lake point is the standout, a point at roughly 7 ft, rated prime for summer rock bass. Plan around the evening in the warm months. A ned rig (small) or a marabou jig covers the summer program.
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 | 1 to 7 ft chart-limited; documented 2 to 10 ft | midday & dawn | Main-lake point (7 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 2 to 7 ft chart-limited; documented 5 to 20 ft | dusk | Main-lake point (7 ft) | Ned rig (small), Marabou jig |
| Fall | 2 to 7 ft chart-limited; documented 8 to 22 ft | midday | Break off the point (3 ft) | Small tube jig, Inline spinner |
| Winter | 2 to 7 ft chart-limited; documented 12 to 30 ft | midday | Deep basin (6 ft) | Tungsten jig + plastic, Small spoon + spike |
4 pieces of structure are mapped here — Main-lake point, around 7 ft, is the deepest of them.
Season dates, license requirements, and size and bag limits for Ontario waters are set by the Ontario fishing regulations (FMZ summary) — and special regulations can apply to Cashen Lake specifically, so confirm the current rules before you fish.

Cashen Lake is about 7 ft (2 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 brook trout, rock bass on Cashen Lake.
Main-lake point is the top-rated area: a point in about 7 ft of water that rates prime for rock bass in summer. The map above holds the full rated-spot list for every species and season.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
