Fishing in Grant County, Wisconsin

What this local map set contains

The Grant County directory currently covers 11 lakes or reservoirs. No chart in this set currently has measured bathymetry; 11 charts are clearly labeled as modeled. Recorded maximum depths range from 4 to 14 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 11 of 11 waters. The most frequently cataloged targets are Largemouth Bass (11), Bluegill (10), Crappie (10), Northern Pike (10) and Yellow Perch (10). 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. Woodman Lake: 12 ft maximum; modeled contours; 8 cataloged target species.
2. Long Slough: 10 ft maximum; modeled contours; 8 cataloged target species.
3. McCartney Lake: 10 ft maximum; modeled 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.
