40-acre lake in Frontenac County, Ontario. The lake tops out around 59 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 40 acres of water rimmed by 1.6 miles of bank, with a single island in the mix. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. The shallow band under 15 ft claims about 17% of the surface — that's where the groceries are. Figure 0.6 mi of water from one end to the other, 0.2 mi at the beam. You'll find it in Frontenac County. The nearest mapped water is Little Clear Lake, 1 mi to the west.
Spring cisco (lake herring) on Black Lake hold shallow, usually 10 to 40 ft. They move out to 18 to 59 ft in summer and finish the year down in 18 to 59 ft. Put Deep basin first on the milk run — a deep basin near 56 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a vertical flutter spoon (small) or a drop-shot micro plastic.

The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 20 to 45 ft for winter. The spot to know is Main-lake point, a point in about 20 ft of water that rates prime for smallmouth bass in fall. Plan around early morning and the evening in the warm months. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
