79-acre lake in Sudbury District, Ontario. The lake tops out around 50 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 rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 80 acres, worked by 2.1 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 67% of this chart. Tip to tip the water measures near 0.7 mi with a 0.4-mi widest point. It sits in Sudbury District. If the bite dies, Muldrew L. 49 and 50 is 1 mi to the south.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Break off the point is the standout, a drop-off at roughly 30 ft, rated prime for summer 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.
