Fishing in Sublette County, Wyoming

What this local map set contains

The Sublette 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 32 to 608 ft, with a median of 150 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 Brook Trout (9), Cutthroat Trout (8), Lake Trout (7), Rainbow Trout (7) and Brown Trout (5). 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. Fremont Lake: 608 ft maximum; modeled contours; 6 cataloged target species.
2. Halfmoon Lake: 282 ft maximum; modeled contours; 6 cataloged target species.
3. Boulder Lake: 249 ft maximum; modeled 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.
