Undens FVO

Undens Fiskerättsforening was formed in the mid-1950s. This association was formed to act an active counterparty against Sweden's first commercial nuclear power plant, which was never subordinated to Unden . To get help with limking measures when ph approached 5.0, Undens FVO association was formed. Since 1977, Undens FVO has received state subsidies for liming measures.

Limestone crusher has been drowned in the playgrounds of the redding. Undes influences are calcified annually by boat and helicopter.

Water samples are taken 4 times / year at 5 predetermined places in order to be able to follow water quality over time. We have very good values ​​and this is very important that it is maintained. Fishing rules are introduced to ensure sustained fishing.
