177-acre lake in Sudbury District, Ontario. The lake tops out around 14 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 177 acres wrapped in 2.4 miles of bank. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Call it 0.7 mi long by 0.6 mi wide at the broadest reach. Sudbury District claims this one. Nimitz L. 15 sits 2 mi northeast — the closest neighbouring chart.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 4 to 14 ft, wintering in 4 to 14 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.
