Digital DjupkartaThe bottom of the lake, as it was measured.

Depth maps for 3,384 Swedish lakes: contours, edges and holes, in full screen. The map is free on every lake in Sweden. With a pass for your lake, tap the water to read the depth, follow the depth under your boat, or tap two points and see the bottom between them.

Every shape here is drawn from the lake's own survey: the same picture you open on the site.

A map you can ask questions

Tovåssjön's depth map with one tap on its deepest point: depth here, 22.7 metres — One tap on Tovåssjön's deepest measured point: 22.7 m. The map, distance and area are free on every lake; the depth tools come with a pass for the lake.

Depth where you pointHow deep is it just there?
Depth under the boatHow deep is it under me, right now?
Follow one depthAm I still on the 8 to 10 m band? The phone buzzes when you leave it.
Cross-sectionWhat does the bottom look like between these two points?
Edges and holesWhere are the deepest holes, the steepest edges and the shallow rises? Tap one and the map goes there.
Plan your holesOn the ice: where is the depth I want to drill on, how far, and which way?
Distance and areaHow far is it over there, and how big is this spot? Free on every lake.

For clubsfree

A depth map on your club's website

Fishing associations, clubs, campsites and cabin villages can put a lake card on their own website: the lake's picture, its deepest point, its depth bands and its area, with a link that opens the map. Wide or narrow, light or dark, one line to copy. It works for any of the 3,384 lakes, and it gets better by itself when the lake's map does.

Near youfree

Word when a lake nearby gets its map

New lakes get their depth maps every week. Watch the lakes near you, and an e-mail comes when one within 25 km gets its map. A place on the water can be shared too: a link that opens the free map at the spot, with your note.

“Sounded by hand. Fitted for you.”

Behind every map is a real survey: sounding lines run from boat and ice, many of them long ago. Each one is fitted to the lake's own shoreline, so the depth lands where it was measured.

Find your lake.The map is free on every lake. The depth is a pass for one lake: 20 kr for a week, 100 kr for a year, paid once. Nothing renews by itself.
