7,084-acre lake in Thunder Bay District, Ontario. The lake tops out around 20 ft. The depth data here comes from the Ontario MNRF survey of 1974, a decades-old survey (an MNRF lake survey). Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 7,115 acres, worked by 28.2 miles of shoreline, broken up by 10 islands. The 2.4 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 7 mi end to end and 2.7 mi across at its widest. It sits in Thunder Bay District. Sunset Lake sits 3 mi east — the closest neighbouring chart.
The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 6 to 20 ft before dropping to 6 to 20 ft for winter. The spot to know is Break off the point, a drop-off in about 7 ft of water that rates prime for walleye in fall. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Gravel shoal (2 ft) | 1/8 oz jig + minnow, Hair jig |

In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 6 to 20 ft before dropping to 6 to 20 ft for winter. Fall yellow perch concentrate at Deep basin, a prime-rated deep basin around 20 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
