Fishing in St. Lawrence County, New York

What this local map set contains

The St. Lawrence 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 30 to 140 ft, with a median of 60 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 Lake Trout (3), Smallmouth Bass (3), Brown Bullhead (2), Largemouth Bass (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. Pleasant Lake: 30 ft maximum; survey-backed contours; 6 cataloged target species.
2. Star Lake: 60 ft maximum; survey-backed contours; 5 cataloged target species.
3. Five Falls Reservoir: 40 ft maximum; survey-backed 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.
