How deep is Black Lake?

Black Lake reaches a maximum depth of 50 feet, according to the Michigan DNR Inland Lake Contours survey. Most of the lake is shallower, with 10 mapped depth bands between the shoreline and the deepest hole.

Where is the deepest part of Black Lake?

The deepest surveyed water on Black Lake sits toward the southern end of the lake, inside the 50 ft contour. The interactive depth map above shows the full basin outline and the breaks leading into it.

How to fish Black Lake: mid-depth structure water

With 50 feet at its deepest, the fish-holding structure is the mid-depth contour: drop-offs, points and inside turns between the shallows and the basin. Use the 10 mapped depth bands to find where contour lines pinch together, which marks the sharpest breaks, and work those edges first, especially early season and again in the fall as fish follow bait between depths.

Ice fishing on Black Lake

Black Lake is a classic ice-fishing depth: enough water to hold fish all winter without the long freeze-up of a deep basin. Start on the deepest mapped hole at first light, then work the breaks where contour lines tighten. Mid-depth flats near the basin edge produce through midday. Always verify ice thickness locally before walking out.
