What this local map set contains

The Algoma District directory currently covers 1026 lakes or reservoirs. 720 charts use measured bathymetry from a published source; 306 charts are clearly labeled as modeled. Recorded maximum depths range from 3 to 380 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 1026 of 1026 waters. The most frequently cataloged targets are Brook Trout (631), Lake Trout (344), Yellow Perch (322), Northern Pike (267) and Walleye (203). 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. Bright Lake: 30 ft maximum; survey-backed contours; 19 cataloged target species.
  2. Echo Lake: 89 ft maximum; survey-backed contours; 16 cataloged target species.
  3. Rock Lake: 70 ft maximum; survey-backed contours; 16 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.
