92-acre lake in Parry Sound District, Ontario. The lake tops out around 11 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. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 91 acres, worked by 1.7 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. The basin spans about 0.5 mi end to end and 0.4 mi across at its widest. It sits in Parry Sound District. If the bite dies, Newell Lake is 0 mi to the northeast.
Spring puts yellow perch in skinny water — 3 to 11 ft is the zone. Summer fish stay in 3 to 11 ft, and winter fish hold in 3 to 11 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring 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.
