65-acre lake in Algoma District, Ontario. The lake tops out around 26 ft. The depth data here comes from the Ontario MNRF survey of 1987 (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
Closs Lake maps at 66 acres behind 2 miles of shoreline. A middling shoreline index (1.8) gives it some bays to work without being a maze. 33% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 0.8 mi with a 0.2-mi widest point. It sits in Algoma District. Its nearest charted neighbour, McCarthy Lake, is 1 mi to the west.
When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 8 to 26 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 26 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (12 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 26 ft | dawn & dusk | Deep basin (26 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (12 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (18 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 8 to 26 ft; cold water stacks them in 8 to 26 ft. Top water on the chart: Break off the point, a drop-off in the 18 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (12 ft) | 1/8 oz jig + minnow, Hair jig |

| Winter | 8 to 26 ft | dusk & dawn | Deep basin (26 ft) | Jigging spoon + minnow head, Rattle bait |

Shallow bay flat is the standout, a weed flat at roughly 5 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

The summer box starts with a drop shot (goby/minnow) or a ned rig.

Anglers target brook trout, walleye, yellow perch, smallmouth bass, rock bass, pumpkinseed, brown bullhead on Closs Lake. This isn't a survey of the lake — none is on record for it — but an informed estimate from the species Ontario's MNRF recorded in the nearest surveyed lakes, filtered to this lake's depth and habitat.
Break off the point is the top-rated area: a drop-off in about 18 ft of water that rates prime for walleye in fall. 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.
