Fishing in Marquette County, Michigan

What this local map set contains

The Marquette County directory currently covers 48 lakes or reservoirs, 1 river. 48 charts use measured bathymetry from a published source; 1 chart is clearly labeled as modeled. Recorded maximum depths range from 5 to 162 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 49 of 49 waters. The most frequently cataloged targets are Largemouth Bass (48), Smallmouth Bass (48), Yellow Perch (48), Pumpkinseed (31) and Bluegill (30). 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. Lake Angeline: 162 ft maximum; survey-backed contours; 15 cataloged target species.
2. Sporley Lake: 42 ft maximum; survey-backed contours; 15 cataloged target species.
3. Engman Lake: 36 ft maximum; survey-backed contours; 15 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.
