18-acre lake in Sudbury District, Ontario. The lake tops out around 18 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. 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.
The drawn water covers 17 acres wrapped in 1 miles of bank. A middling shoreline index (1.7) gives it some bays to work without being a maze. Tip to tip the water measures near 0.4 mi. Sudbury District claims this one. Its nearest charted neighbour, Clearsilver Lake, is 1 mi to the west.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 5 to 18 ft, wintering in 5 to 18 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

Spring northern pike on Log Boom Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 5 to 18 ft, and by winter most fish are in 5 to 15 ft.

The summer box starts with a bucktail or a weedless spoon over cabbage.

Spring puts pumpkinseed in skinny water — 1 to 8 ft is the zone. Warm water sends them out to 2 to 10 ft; cold water stacks them in 6 to 18 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring pumpkinseed. Plan around the evening and early morning in the warm months. A micro tube or a sponge spider (fly) covers the summer program.
