3. Koukjärvi: 33 ft · Survey depth data; 5 cataloged target species.

Start with a survey-backed chart when exact contour shape matters most. Water guides preserve access and species information without displaying approximated depth contours. Access is separate from map coverage: confirm launches, shore rights, closures and posted rules before making the trip.
