1,991-acre lake in Peterborough County, Ontario. The lake tops out around 22 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 season-by-season read for each species follows, from the map's own numbers.
The outline encloses 2,000 acres, worked by 22.4 miles of shoreline, broken up by 19 islands. An index of 3.6 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 97% of this chart. Tip to tip the water measures near 4.8 mi with a 1.3-mi widest point. It sits in Peterborough County. Its nearest charted neighbour, Buckhorn Lake, is 3 mi to the northwest.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 7 to 22 ft; cold water stacks them in 7 to 22 ft. Deep basin is the standout, a deep basin at roughly 21 ft, rated prime for fall 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
