133-acre lake in Cochrane District, Ontario. The lake tops out around 40 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. The rest of this page walks each species through its year, using the map's own scoring.
Lac Brochet maps at 134 acres behind 2.7 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. Roughly 39% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 1 mi with a 0.3-mi widest point. Cochrane District claims this one. Muskrat Lake sits 1 mi east — the closest neighbouring chart.
In spring, lake whitefish run shallow here, mostly 12 to 40 ft. Summer keeps them at 12 to 40 ft, and they winter in 12 to 40 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 39 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.

Spring cisco (lake herring) concentrate at Deep basin, a prime-rated deep basin around 39 ft. Fish it in early morning and you'll meet the bite.

The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 30 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.

|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (6 ft) | 1/8 oz jig + minnow, Hair jig |

In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 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 and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
