Fishing in Teton County, Montana

What this local map set contains

The Teton County directory currently covers 5 lakes or reservoirs. 5 charts use measured bathymetry from a published source; none rely on modeled contours. Recorded maximum depths range from 4 to 165 ft, with a median of 24 ft. Those figures describe each chart's deepest recorded or modeled point, not a safe navigation depth.

Species records are attached to 5 of 5 waters. The most frequently cataloged targets are Arctic Grayling (3), Rainbow Trout (3), Brook Trout (2), Cutthroat Trout (2) and Northern Pike (2). 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. Pishkun Reservoir: 78 ft maximum; survey-backed contours; 6 cataloged target species.
2. Gibson Reservoir: 165 ft maximum; survey-backed contours; 4 cataloged target species.
3. Tunnel Lake: 24 ft maximum; survey-backed contours; 2 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.
