Fiske i Oslo kommune, Norge

What this local map set contains

The Oslo Municipality directory currently covers 15 lakes or reservoirs. 15 charts use measured bathymetry from a published source; none rely on modeled contours. Recorded maximum depths range from 13 to 184 ft, with a median of 49 ft. Those figures describe each chart's deepest recorded or modeled point, not a safe navigation depth.

Species records are attached to 15 of 15 waters. The most frequently cataloged targets are Brown Trout (15), European Perch (15), Northern Pike (15), Lake Whitefish (15) and Arctic Char (12). 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. Bogstadvannet: 34 ft maximum; survey-backed contours; 7 cataloged target species.
2. Hakkloa: 184 ft maximum; survey-backed contours; 5 cataloged target species.
3. Kalvsjøen: 171 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.
