28-acre lake in Haliburton County, Ontario. The lake tops out around 20 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 29 acres, worked by 1.1 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 73% of the surface — that's where the groceries are. Tip to tip the water measures near 0.4 mi with a 0.2-mi widest point. Haliburton County claims this one. Its nearest charted neighbour, Hosiery Lake, is 0 mi to the southeast.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 6 to 20 ft, wintering in 6 to 20 ft. Fall yellow perch concentrate at Deep basin, a prime-rated deep basin around 20 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
