Fishing in Oconto County, Wisconsin

What this local map set contains

The Oconto County directory currently covers 135 lakes or reservoirs. 4 charts use measured bathymetry from a published source; 131 charts are clearly labeled as modeled. Recorded maximum depths range from 3 to 65 ft, with a median of 21 ft. Those figures describe each chart's deepest recorded or modeled point, not a safe navigation depth.

Species records are attached to 135 of 135 waters. The most frequently cataloged targets are Bluegill (129), Crappie (129), Yellow Perch (129), Largemouth Bass (117) and Northern Pike (78). 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. Kelly Lake: 41 ft maximum; survey-backed contours; 6 cataloged target species.
2. Boundary Lake: 19 ft maximum; survey-backed contours; 6 cataloged target species.
3. Nelligan Lake: 23 ft maximum; survey-backed contours; 5 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.
