Fishing in Columbia County, Wisconsin

What this local map set contains

The Columbia County directory currently covers 18 lakes or reservoirs, 1 river. No chart in this set currently has measured bathymetry; 19 charts are clearly labeled as modeled. Recorded maximum depths range from 3 to 82 ft, with a median of 8 ft. Those figures describe each chart's deepest recorded or modeled point, not a safe navigation depth.

Species records are attached to 19 of 19 waters. The most frequently cataloged targets are Bluegill (19), Crappie (19), Yellow Perch (19), Largemouth Bass (15) and Northern Pike (13). 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. Wisconsin River (Dells): 12 ft maximum; modeled contours; 16 cataloged target species.
2. Swan Lake: 82 ft maximum; modeled contours; 7 cataloged target species.
3. Silver Lake: 42 ft maximum; modeled contours; 7 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.
