  Örebro län and Västra Götalands län / Laxå, Karlsborg, Töreboda and Gullspång municipality.

Lake Unden in Tiveden is classified as a national interest. It is a groundwater lake, the inflow through the bottom is about 40% of the total inflow. Unden is one of our country's foremost large char lakes, both the lake's topography and its ecosystem are suitable for char. The bottom has clear cold water, the average depth of the lake is 32 m and the maximum depth is stated at 108 m.

The area is 9540 ha and the lake has 13 streams as inflows. Draining takes place through three power plants located in Edsån that connects Unden with Lake Viken. The average water flow in Edsån is 3.5 m3 per second. Göta Kanalbolag AB, which has the original water right, provides Göta Kanal with the required water level for sailing.

In the lake there is char, trout, whitefish (3 varieties), pike, perch, lake, smelt, roe / bone roe, roach, osprey, yarrow, grayling. The largest caught fish in Unden are; char 10.5 kg, trout 14.4 kg, whitefish 3.2 kg, perch 2.8 kg and pike 17.0 kg.
The trout play in running water in the larger streams. The newly hatched trout live one to two years in the hatching basin, and then go out into the lake and eat large ones. A number of these return after a few years to the birth creek for new play.

The tributaries and Edsån which connects Unden with Viken does not belong to the fisheries conservation area.

Undens FVO

Undens Fiskerrettförening was formed in the mid-1950s. This association was formed to act as an active counterpart to Sweden's first commercial nuclear power plant, which was never placed at Unden.

To get help with liming measures when the pH value in the lake approached 5.0, the Undens Fiskevårds AREA Association was formed. Since 1977, Undens FVOF has received government grants for liming measures.

Limestone crusher has been run out on the char's playgrounds. The flow of the ovens is calculated annually by boat and helicopter. Water samples are taken 4 times a year at 5 predetermined locations to monitor water quality over time. The pH value of the water is now good and is kept at the right level with the aid of liming. Fishing rules have been introduced to maintain sustainable fishing.
