Robinson Lake reaches a maximum depth of 50 feet, according to the Indiana DNR Lake Bathymetry survey. Most of the lake is shallower, with 5 mapped depth bands between the shoreline and the deepest hole.

Where is the deepest part of Robinson Lake?

The deepest surveyed water on Robinson Lake sits toward the southwestern corner 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 accurate is this Robinson Lake depth map?

The contours come from the Indiana DNR Lake Bathymetry survey. Depths change over time with water levels and sediment, so treat this map as a planning guide for fishing, and never use it for navigation. Per Indiana DNR, the data are graphical representations for reference only, not a survey instrument.

How to fish Robinson 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 5 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 Robinson Lake

Robinson 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.
