Fishing in Ashland County, Wisconsin

What this local map set contains

The Ashland County directory currently covers 68 lakes or reservoirs. 3 charts use measured bathymetry from a published source; 65 charts are clearly labeled as modeled. Recorded maximum depths range from 5 to 48 ft, with a median of 14 ft. Those figures describe each chart's deepest recorded or modeled point, not a safe navigation depth.

Species records are attached to 68 of 68 waters. The most frequently cataloged targets are Bluegill (64), Crappie (64), Pumpkinseed (64), Yellow Perch (64) and Largemouth Bass (45). 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. Bad River Slough: 13 ft maximum; survey-backed contours; 8 cataloged target species.
2. Mineral Lake: 29 ft maximum; survey-backed contours; 7 cataloged target species.
3. Eureka Lake: 25 ft maximum; survey-backed contours; 6 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.
