Fishing in Iron County, Michigan

What this local map set contains

The Iron County directory currently covers 57 lakes or reservoirs. 56 charts use measured bathymetry from a published source; 1 chart is clearly labeled as modeled. Recorded maximum depths range from 8 to 110 ft, with a median of 30 ft. Those figures describe each chart's deepest recorded or modeled point, not a safe navigation depth.

Species records are attached to 57 of 57 waters. The most frequently cataloged targets are Smallmouth Bass (57), Yellow Perch (57), Bluegill (55), Largemouth Bass (53) and Rock Bass (41). These are coverage counts, not abundance estimates or catch forecasts; open the individual map to see the evidence and seasonal context attached to that water.

Three useful maps to compare first

1. Long Lake: 105 ft maximum; survey-backed contours; 15 cataloged target species.
2. Third Fortune Lake: 55 ft maximum; survey-backed contours; 13 cataloged target species.
3. Glidden Lake: 30 ft maximum; survey-backed contours; 13 cataloged target species.

Start with a survey-backed chart when exact contour shape matters most. Use a modeled chart as broad planning context, then verify depths on the water. Comparing the three examples above also shows whether this area offers one dominant basin type or genuinely different shallow, deep, lake and river options. Access is separate from map coverage: confirm launches, shore rights, closures and posted rules before making the trip.
