87-acre lake in Leeds and Grenville United Counties, Ontario. The lake tops out around 30 ft. The depth data here comes from the Ontario MNRF survey of 1968, a decades-old survey (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
On the chart, Lyndhurst Lake draws 87 acres inside 1.7 miles of shoreline. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. About 49% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 0.5 mi with a 0.5-mi widest point. The water lies in Leeds and Grenville United Counties. Closest neighbour on DepthScout: Little Long Lake, 2 mi northeast of here.
Spring yellow perch on Lyndhurst Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 9 to 30 ft.

The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
