Fishing in York Regional Municipality, Ontario

What this local map set contains

The York Regional Municipality directory currently covers 16 lakes or reservoirs. 10 charts use measured bathymetry from a published source; 6 charts are clearly labeled as modeled. Recorded maximum depths range from 15 to 135 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 16 of 16 waters. The most frequently cataloged targets are Brown Bullhead (16), Pumpkinseed (13), Largemouth Bass (12), Yellow Perch (11) and Northern Pike (9). 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. Lake Simcoe: 135 ft maximum; survey-backed contours; 17 cataloged target species.
2. Wilcox Lake: 53 ft maximum; survey-backed contours; 9 cataloged target species.
3. Hackett Lake: 55 ft maximum; survey-backed contours; 7 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.
