Fishing in Rock County, Wisconsin

What this local map set contains

The Rock County directory currently covers 11 lakes or reservoirs, 1 river. No chart in this set currently has measured bathymetry; 12 charts are clearly labeled as modeled. Recorded maximum depths range from 6 to 37 ft, with a median of 15 ft. Those figures describe each chart's deepest recorded or modeled point, not a safe navigation depth.

Species records are attached to 12 of 12 waters. The most frequently cataloged targets are Bluegill (12), Crappie (12), Largemouth Bass (11), Yellow Perch (11) and Northern Pike (8). 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. Rock River (WI): 14 ft maximum; modeled contours; 10 cataloged target species.
2. Willies Pond: 14 ft maximum; modeled contours; 8 cataloged target species.
3. Leota Lake: 15 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.
