Fishing in Mineral County, Montana

What this local map set contains

The Mineral County directory currently covers 19 lakes or reservoirs. 19 charts use measured bathymetry from a published source; none rely on modeled contours. Recorded maximum depths range from 12 to 180 ft, with a median of 50 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 Cutthroat Trout (12), Rainbow Trout (12), Brook Trout (10), Channel Catfish (10) and Crappie (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. Crystal Lake (Mineral): 120 ft maximum; survey-backed contours; 10 cataloged target species.
2. Diamond Lake (Mineral): 25 ft maximum; survey-backed contours; 10 cataloged target species.
3. Lost Lake (Mineral): 180 ft maximum; survey-backed contours; 9 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.
