Kolsnaren and Viren are lakes in Södermanland, Katrineholms and Vingåkers municipalities that are part of the Nyköpingsån water system. Kolsnaren is 12 km² and as deepest 12 m as it flows through Viren to Nyköpingsån.
In the lakes there are perch, pike, gazelle, eel, lake and implanted rainbow. Gossip and rainbow have been implanted continuously by the association in recent years.
Interest in sport fishing in the lakes has increased and we are selling more and more fishing licenses. This has caused us to cope with quite a number of fishery measures. Gossiping has taken place almost every year, we have also sat in the rainbow salmon.
In the lakes there is also a marina.
Kolsnaren-Viren FVOF comprises the lakes Kolsnaren (area: 1147 ha) and Viren (1190 ha), which are located in western Södermanland and are part of the Nyköpingsån water system.
The association was formed in 1987 after several appeals and all legal tours confirmed the formation of the Government Court in 1990. The water owners' fishing rights with all tools remain unchanged, however all fixed fishing gear has to be awakened and labeled with the fishing rights number. However, this fishing is very limited.
We have charts where we specified the depth of the bottom, based on the depth of depth.
