What's the best way to find and mark good ice fishing spots?

April 6, 2026

Quick Answer

Identify potential ice fishing spots using topographic maps, sonar units, and local knowledge. Mark good spots with GPS coordinates, flags, or stakes. Verify ice thickness before traversing.

Analyzing Ice Fishing Spots

When searching for ice fishing spots, it’s essential to consider factors like structure, depth, and accessibility. Topographic maps can help identify areas with submerged logs, rocks, or weed beds that attract fish. Sonar units can reveal underwater structures and detect fish concentrations. Local knowledge from experienced anglers or fishing guides can also provide valuable insights into the best fishing spots.

Marking Good Spots

Once you’ve identified a promising spot, mark it for future reference. Using a GPS unit, record the coordinates of the location, including the latitude, longitude, and depth. Attach a flag or stake to the ice to serve as a visual marker. This allows you to quickly locate the spot on subsequent trips. If you don’t have a GPS, use natural landmarks like trees or rocks to help you remember the location.

Verifying Ice Thickness

Before traversing the ice to reach your marked spot, ensure it’s safe to do so. Use a tape measure or a device specifically designed for measuring ice thickness to check for adequate support. A minimum of 4 inches of clear ice is recommended for most ice fishing activities. Avoid areas with cracks, honeycombing, or other signs of structural weakness.
